Dative case

In grammar, the dative case (abbreviated, or sometimes when it is a core argument) is a grammatical case used in some languages to indicate the recipient or beneficiary of an action, as in "Maria Jacobo potum dedit", Latin for "Maria gave Jacob a drink". In this example, the dative marks what would be considered the indirect object of a verb in English.

Sometimes the dative has functions unrelated to giving. In Scottish Gaelic and Irish, the term dative case is used in traditional grammars to refer to the prepositional case-marking of nouns following simple prepositions and the definite article. In Georgian and Hindustani (Hindi-Urdu), the dative case can also mark the subject of a sentence. This is called the dative construction. In Hindi, the dative construction is not limited to only certain verbs or tenses and it can be used with any verb in any tense or mood.

The dative was common among early Indo-European languages and has survived to the present in the Balto-Slavic branch, the Germanic branch, Albanian and others. It also exists in similar forms in several non-Indo-European languages, such as the Uralic family of languages. In some languages, the dative case has assimilated the functions of other, now extinct cases. In Ancient Greek, the dative has the functions of the Proto-Indo-European locative and instrumental as well as those of the original dative.

Under the influence of English, which uses the preposition "to" for (among other uses) both indirect objects (give to) and directions of movement (go to), the term "dative" has sometimes been used to describe cases that in other languages would more appropriately be called lative.

Etymology
"Dative" comes from Latin cāsus datīvus ("case for giving"), a translation of Greek δοτικὴ πτῶσις, dotikē ptôsis ("inflection for giving"). Dionysius Thrax in his Art of Grammar also refers to it as epistaltikḗ "for sending (a letter)", from the verb epistéllō "send to", a word from the same root as epistle.

English
The Old English language had a dative case; however, the English case system gradually fell into disuse during the Middle English period, when the accusative and dative of pronouns merged into a single oblique case that was also used with all prepositions. This conflation of case in Middle and Modern English has led most modern grammarians to discard the "accusative" and "dative" labels as obsolete in reference to English, often using the term "objective" for oblique.

Set expressions
The dative case is rare in modern English usage, but it can be argued that it survives in a few set expressions. One example is the word "methinks", with the meaning "it seems to me". It survives in this fixed form from Old English (having undergone, however, phonetic changes with the rest of the language), in which it was constructed as "[it]" + "me" (the dative case of the personal pronoun) + "thinks" (i.e., "seems", < Old English þyncan, "to seem", a verb closely related to the verb þencan, "to think", but distinct from it in Old English; later it merged with "think" and lost this meaning).

Relic pronouns
The modern objective case pronoun whom is derived from the dative case in Old English, specifically the Old English dative pronoun "hwām" (as opposed to the modern subjective "who", which descends from Old English "hwā") – though "whom" also absorbed the functions of the Old English accusative pronoun "hwone". It is also cognate to the word "wem" (the dative form of "wer") in German. The OED defines all classical uses of the word "whom" in situations where the indirect object is not known – in effect, indicating the anonymity of the indirect object.

Likewise, some of the object forms of personal pronouns are remnants of Old English datives. For example, "him" goes back to the Old English dative him (accusative was hine), and "her" goes back to the dative hire (accusative was hīe). These pronouns are not pure datives in modern English; they are also used for functions previously indicated by the accusative.

Modern English
The indirect object of the verb may be placed between the verb and the direct object of the verb: "he gave me a book" or "he wrote me a poem."

The indirect object may also be expressed using a prepositional phrase using "to": "he gave a book to me".

German
In general, the dative (German: Dativ) is used to mark the indirect object of a German sentence. For example:
 * Ich schickte dem Mann(e) das Buch. (literally: I sent "to the man" the book.) – Masculine
 * Ich gab der Frau den Stift zurück. (literally: I gave "to the woman" the pencil back.) – Feminine
 * Ich überreiche dem Kind(e) ein Geschenk. (literally: I hand "to the child" a present.) – Neuter

In English, the first sentence can be rendered as "I sent the book to the man" and as "I sent the man the book", where the indirect object is identified in English by standing in front of the direct object. The normal word order in German is to put the dative in front of the accusative (as in the example above). However, since the German dative is marked in form, it can also be put after the accusative: Ich schickte das Buch dem Mann(e). The (e) after Mann and Kind signifies a now largely archaic -e ending for certain nouns in the dative. It survives today almost exclusively in set phrases such as zu Hause (at home, lit. to house), im Zuge (in the course of), and am Tage (during the day, lit. at the day), as well as in occasional usage in formal prose, poetry, and song lyrics.

Some masculine nouns (and one neuter noun, Herz [heart]), referred to as weak nouns or n-nouns, take an -n or -en in the dative singular and plural. Many are masculine nouns ending in -e in the nominative (such as Name [name], Beamte [officer], and Junge [boy]), although not all such nouns follow this rule. Many also, whether or not they fall into the former category, refer to people, animals, professions, or titles; exceptions to this include the aforementioned Herz and Name, as well as Buchstabe (letter), Friede (peace), Obelisk (obelisk), Planet (planet), and others.

Certain German prepositions require the dative: aus (from), außer (out of), bei (at, near), entgegen (against), gegenüber (opposite), mit (with), nach (after, to), seit (since), von (from), and zu (at, in, to). Some other prepositions (an [at], auf [on], entlang [along], hinter [behind], in [in, into], neben (beside, next to), über [over, across], unter [under, below], vor [in front of], and zwischen [among, between]) may be used with dative (indicating current location), or accusative (indicating direction toward something). Das Buch liegt auf dem Tisch(e) (dative: The book is lying on the table), but Ich lege das Buch auf den Tisch (accusative: I put the book onto the table).

In addition the four prepositions [an]statt (in place of), trotz (in spite of), während (during), and wegen (because of) which require the genitive in modern formal language, are most commonly used with the dative in colloquial German. For example, "because of the weather" is expressed as wegen dem Wetter instead of the formally correct wegen des Wetters. Other prepositions requiring the genitive in formal language, are combined with von ("of") in colloquial style, e.g. außerhalb vom Garten instead of außerhalb des Gartens ("outside the garden").

The concept of an indirect object may be rendered by a prepositional phrase. In this case, the noun's or pronoun's case is determined by the preposition, not by its function in the sentence. Consider this sentence: Here, the subject, Ich, is in the nominative case, the direct object, das Buch, is in the accusative case, and zum Verleger is in the dative case, since zu always requires the dative (zum is a contraction of zu + dem). However: In this sentence, Freund is the indirect object, but, because it follows an (direction), the accusative is required, not the dative.
 * Ich sandte das Buch zum Verleger. 'I sent the book to the editor.'
 * Ich habe das Buch an meinen Freund (accusative) weitergegeben. 'I forwarded the book to my friend.' (weitergeben = lit.: to give further).

All of the articles change in the dative case.

Some German verbs require the dative for their direct objects. Common examples are antworten (to answer), danken (to thank), gefallen (to please), folgen (to follow), glauben (to believe), helfen (to help), and raten (to advise). In each case, the direct object of the verb is rendered in the dative. For example:
 * Meine Freunde helfen mir. (My friends help me.)

These verbs cannot be used in normal passive constructions, because German allows these only for verbs with accusative objects. It is therefore ungrammatical to say: *Ich werde geholfen. "I am helped." Instead a special construction called "impersonal passive" must be used: Mir wird geholfen, literally: "To me is helped." A colloquial (non-standard) way to form the passive voice for dative verbs is the following: Ich kriege geholfen, or: Ich bekomme geholfen, literally: "I get helped". The use of the verb "to get" here reminds us that the dative case has something to do with giving and receiving. In German, help is not something you perform on somebody, but rather something you offer them.

The dative case is also used with reflexive (sich) verbs when specifying what part of the self the verb is being done to: Cf. the respective accord in French: "Les enfants se sont lavés" (the children have washed themselves) vs. "Les enfants se sont lavé" [uninflected] "les mains" (... their hands).
 * Ich wasche mich. – accusative (I wash myself.)
 * Ich wasche mir die Hände. – dative (I wash my hands, literally "I wash for myself the hands")

German can use two datives to make sentences like: Sei mir meinem Sohn(e) gnädig! "For my sake, have mercy on my son!" Literally: "Be for me to my son merciful." The first dative mir ("for me") expresses the speaker's commiseration (much like the dativus ethicus in Latin, see below). The second dative meinem Sohn(e) ("to my son") names the actual object of the plea. Mercy is to be given to the son for or on behalf of his mother/father.

Adjective endings also change in the dative case. There are three inflection possibilities depending on what precedes the adjective. They most commonly use weak inflection when preceded by a definite article (the), mixed inflection after an indefinite article (a/an), and strong inflection when a quantity is indicated (many green apples).

Latin
There are several uses for the dative case (Dativus):
 * Dativus finalis (dative of purpose), e.g. non scholae sed vitae – "[we learn] not for school, but for life", auxilio vocare – "to call for help", venio auxilio – "I'm coming for help", accipio dono – "I receive [this] as a gift" or puellae ornamento est – "[this] is for the girl's decoration", or "... for decoration for the girl" (as puellae could be either dative or genitive)
 * Dativus commŏdi (incommodi), which means action for (or against) somebody, e.g., Graecis agros colere – "to till fields for Greeks"; Combination of Dativus commodi and finalis (double dative): tibi laetitiae "to you for joy"
 * Dativus possessivus (possessive dative) which means possession, e.g. angelis alae sunt – literally "to (or for) the angels are wings", this is typically found with a copula and translated as "angels have wings".
 * Dativus ethicus (ethic dative) indicates that the person in the dative is or should be especially concerned about the action, e.g. Quid mihi Celsus agit? "What is Celsus doing for me?" (expressing the speaker being especially interested in what Celsus is doing for him or her); or Cui prodest? "Whose interest does this serve?" (literally "To whom does this do good?")
 * Dativus auctoris, meaning; 'in the eyes of', e.g., vir bonus mihi videtur 'he seems to me to be a good man'.
 * The dative expresses agency with the gerundive when the gerundive is used to convey obligation or necessity, e.g., haec nobis agenda sunt, 'these things must be done by us.'

Ancient
In addition to its main function as the dativus, the dative case has other functions in Classical Greek: (The chart below uses the Latin names for the types of dative; the Greek name for the dative is δοτική πτῶσις, like its Latin equivalent, derived from the verb "to give"; in Ancient Greek, δίδωμι.)
 * Dativus finalis: The dativus finalis, or the 'dative of purpose', is when the dative is used to denote the purpose of a certain action. For example:
 * "τῷ βασιλεῖ μάχομαι"
 * "I fight for the king".
 * "θνῄσκω τῇ τιμῇ"
 * "I die for honour".
 * Dativus commŏdi (incommodi): The dativus commodi sive incommodi, or the 'dative of benefit (or harm)' is the dative that expresses the advantage or disadvantage of something for someone. For example:
 * For the benefit of: "πᾶς ἀνὴρ αὑτῷ πονεῖ" (Sophocles, Ajax 1366).
 * "Every man toils for himself".
 * For the harm or disadvantage of: "ἥδε ἡ ἡμέρα τοῖς Ἕλλησι μεγάλων κακῶν ἄρξει." (Thucydides 2.12.4).
 * "This day will be the beginning of great sorrows for the Greeks (i.e., for their disadvantage)".
 * Dativus possessivus: The dativus possessivus, or the 'dative of possession' is the dative used to denote the possessor of a certain object or objects. For example:
 * "ἄλλοις μὲν γὰρ χρήματά ἐστι πολλὰ καὶ ἵπποι, ἡμῖν δὲ ξύμμαχοι ἀγαθοί." (Thucycdides 1.86.3).
 * "For others have a lot of money and ships and horses, but we have good allies (i.e., To others there is a lot of money...)".
 * Dativus ethicus: The dativus ethicus, or the 'ethic or polite dative,' is when the dative is used to signify that the person or thing spoken of is regarded with interest by someone. This dative is mostly, if not exclusively, used in pronouns. As such, it is also called the "dative of pronouns." For example:
 * "τούτῳ πάνυ μοι προσέχετε τὸν νοῦν." (Demosthenes 18.178).
 * "Pay close attention to this, I beg you (i.e., please pay..)".
 * "ὦ μῆτερ, ὡς καλός μοι ὁ πάππος." (Xenophon, Cyropaedia 18.178).
 * "Oh, mother, how handsome grandpa is (I've just realized!)".
 * Dativus auctoris: The dativus auctoris, or the 'dative of agent,' is the dative used to denote the doer of an action. Note, however, that in Classical Greek, the agent is usually in the genitive after ὑπό (by, at the hands of). The agent is in the dative most often with the perfect and pluperfect passive, and with the verbal adjective in -τέος.  For example:
 * "πολλαὶ θεραπεῖαι τοῖς ἰατροῖς εὕρηνται." (Isocrates 8.39)
 * "Many cures have been discovered by doctors."
 * Dativus instrumenti: The dativus instrumenti, or the 'dative of instrument,' is when the dative is used to denote an instrument or means of a certain action (or, more accurately, as the instrumental case). For example:
 * "με κτείνει δόλῳ." (Homer, Odyssey 9.407)
 * "He kills me with a bait (i.e., by means of a bait)."
 * Dativus modi: The dativus modi, or the 'dative of manner,' is the dative used to describe the manner or way by which something happened. For example:
 * "νόσῳ ὕστερον ἀποθανόντα." (Thucydides 8.84)
 * "having died of (from) a disease."
 * Dativus mensurae: The dativus mensurae, or the 'dative of measurement,' is the dative used to denote the measurement of difference. For example:
 * "τῇ κεφαλῇ μείζονα." (Plato, Phaedo 101a)
 * "taller by a head."
 * "μακρῷ ἄριστος." (Plato, Laws 729d)
 * "by far the best."

Modern
The dative case, strictly speaking, no longer exists in Modern Greek, except in fossilized expressions like δόξα τω Θεώ (from the ecclesiastical τῷ Θεῷ δόξα, "Glory to God") or εν τάξει (ἐν τάξει, lit. "in order", i.e. "all right" or "OK"). Otherwise, most of the functions of the dative are expressed by the genitive or by prepositional phrases.

Slavic languages
In Russian, the dative case is used for indicating the indirect object of an action (that to which something is given, thrown, read, etc.). In the instance where a person is the goal of motion, dative is used instead of accusative to indicate motion toward. This is usually achieved with the preposition κ + destination in dative case; К врачу, meaning "to the doctor."

Dative is also the necessary case taken by certain prepositions when expressing certain ideas. For instance, when the preposition по is used to mean "along", its object is always in dative case, as in По бокам, meaning "along the sides."

Other Slavic languages apply the dative case (and the other cases) more or less the same way as does Russian; some languages may use the dative in other ways. The following examples are from Polish:

 * after certain verbs (dziękować komuś "to thank someone", pomóc komuś "to help someone", wierzyć komuś "to believe someone")
 * in certain expressions (Czy podoba ci się piosenka? "Do you like the song?", Jest mi zimno "I'm cold", Jest nam smutno "We're feeling sad", Będzie wam trudniej... "It will be more difficult for you guys"), Śniło jej się, że... "She dreamt that"
 * dativus commodi to indicate action for somebody (Zbuduję temu człowiekowi dom "I will build a house for this person")
 * when something is taken away or something occurs to someone (Zdechł im pies "Their dog died"; Zabrali mu komputer "They took away his computer"; Zepsuł nam się samochód "Our car broke down"; Coś mi się przypomniało "I just remembered something")

Some other kinds of dative use as found in the Serbo-Croatian language are: Dativus finalis (Titaniku u pomoć "to Titanic's rescue"), Dativus commodi/incommodi (Operi svojoj majci suđe "Wash the dishes for your mother"), Dativus possessivus (Ovcama je dlaka gusta "Sheep's hair is thick"), Dativus ethicus (Šta/što mi radi Boni? "What is Boni doing? (I am especially interested in what it is)") and Dativus auctoris (Izgleda mi okej "It seems okay to me").

Unusual in other Indo-European branches but common among Slavic languages, endings of nouns and adjectives are different based on grammatical function. Other factors are gender and number. In some cases, the ending may not be obvious, even when those three factors (function, gender, number) are considered. For example, in Polish, 'syn' ("son") and 'ojciec' ("father") are both masculine singular nouns, yet appear as syn → synowi and ojciec → ojcu in the dative.

Baltic languages
Both Lithuanian and Latvian have a distinct dative case in the system of nominal declensions.

Lithuanian nouns preserve Indo-European inflections in the dative case fairly well: (o-stems) vaikas -> sg. vaikui, pl. vaikams; (ā-stems) ranka -> sg. rankai, pl. rankoms; (i-stems) viltis -> sg. vilčiai, pl. viltims; (u-stems) sūnus -> sg. sūnui, pl. sūnums; (consonant stems) vanduo -> sg. vandeniui, pl. vandenims.

Adjectives in the dative case receive pronominal endings (this might be the result of a more recent development): tas geras vaikas -> sg. tam geram vaikui, pl. tiems geriems vaikams.

The dative case in Latvian underwent further simplifications – the original masculine endings of both nouns and adjectives have been replaced with pronominal inflections: tas vīrs -> sg. tam vīram, pl. tiem vīriem. Also, the final "s" in all Dative forms has been dropped. The only exception is personal pronouns in the plural: mums (to us), jums (to you). In colloquial Lithuanian the final "s" in the dative is often omitted, as well: time geriem vaikam.

In both Latvian and Lithuanian, the main function of the dative case is to render the indirect object in a sentence: (lt) aš duodu vyrui knygą; (lv) es dodu [duodu] vīram grāmatu – I am giving a book to the man.

The dative case can also be used with gerundives to indicate an action preceding or simultaneous with the main action in a sentence: (lt) jam įėjus, visi atsistojo – when he walked in, everybody stood up, lit. to him having walked in, all stood up; (lt) jai miegant, visi dirbo – while she slept, everybody was working, lit. to her sleeping, all were working.

In modern standard Lithuanian, Dative case is not required by prepositions, although in many dialects it is done frequently: (dial.) iki (+D) šiai dienai, (stand.) iki (+G) šios dienos – up until this day.

In Latvian, the dative case is taken by several prepositions in the singular and all prepositions in the plural (due to peculiar historical changes): sg. bez (+G) tevis (without thee) ~ pl. bez (+D) jums (without you); sg. pa (+A) ceļu (along the road) ~ pl. pa (+D) ceļiem (along the roads).

Armenian
In modern Eastern Armenian, the dative is attained by adding any article to the genitive:

 * dog = շուն
 * GEN > շան (of the dog; dog's) with no articles
 * DAT > շանը or շանն (to the dog) with definite articles (-ն if preceding a vowel)
 * DAT > մի շան (to a dog) with indefinite article
 * DAT > շանս (to my dog) with 1st person possessive article
 * DAT > շանդ (to your dog) with 2nd person possessive article

There is a general tendency to view -ին as the standard dative suffix, but only because that is its most productive (and therefore common) form. The suffix -ին as a dative marker is nothing but the standard, most common, genitive suffix -ի accompanied by the definite article -ն. But the dative case encompasses indefinite objects as well, which will not be marked by -ին:

 * Definite DAT > Ես գիրքը տվեցի տղային: (I gave the book to the boy)
 * Indefinite DAT> Ես գիրքը տվեցի մի տղայի: (I gave the book to a boy)

The main function of the dative marking in Armenian is to indicate the receiving end of an action, more commonly the indirect object which in English is preceded by the preposition to. In the use of "giving" verbs like give, donate, offer, deliver, sell, bring... the dative marks the recipient. With communicative verbs like tell, say, advise, explain, ask, answer... the dative marks the listener. Other verbs whose indirect objects are marked by the dative case in Armenian are show, reach, look, approach...

Eastern Armenian also uses the dative case to mark the time of an event, in the same way English uses the preposition at, as in Meet me at nine o' clock.

Hindustani (Hindi-Urdu)
Hindustani (Hindi-Urdu) has true dative case for pronouns, but for nouns the dative case has to be constructed using the dative case-marker (postposition) को کو (ko) to the nouns in their oblique case. Pronouns in Hindustani also have an oblique case, so dative pronouns can also be alternatively constructed using the dative case-marker को کو (ko) with the pronouns in their oblique case, hence forming two sets of synonymous dative pronouns. The following table shows the pronouns in their nominative and their dative forms. Hindustani lacks pronouns in the third person and the demonstrative pronouns double as the third person pronouns.  The table below shows the oblique cases of Hindustani for the nouns boy and girl which take in the dative case-marker after them to assign the combination of the oblique case and the case-marker the dative case. The oblique case of Hindustani by itself has no meaning and adding the case-marker को کو (ko) assigns the oblique case the function of the dative case.  Dative case in Hindustani can also mark the subject of a sentence. This is called the dative construction or quirky subjects. In the examples below the dative pronoun passes the subjecthood test of subject-oriented anaphora binding. The dative subject मुझे مجھے (mujhe) binds the anaphora अपने اپنے  (apne).

Sanskrit
The dative case is known as the "fourth case" (chaturthi-vibhakti) in the usual procedure in the declension of nouns. Its use is mainly for the indirect object.

Hungarian
As with many other languages, the dative case is used in Hungarian to show the indirect object of a verb. For example, Dánielnek adtam ezt a könyvet (I gave this book to Dániel). It has two suffixes, -nak and -nek; the correct one is selected by vowel harmony. The personal dative pronouns follow the -nek version: nekem, neked, etc. This case is also used to express "for" in certain circumstances, such as "I bought a gift for Mother". In possessive constructions the nak/nek endings are also used but this is not the dative form (rather, the attributive or possessive case)

Finnish
Finnish does not have a separate dative case. However, the allative case can fulfill essentially the same role as dative, beyond its primary meaning of directional movement (that is, going somewhere or approaching someone). For example: ''He lahjoittivat kaikki rahansa köyhille (They donated all their money to the poor.) It is similar in Estonian.

Tsez
In the Northeast Caucasian languages, such as Tsez, the dative also takes the functions of the lative case in marking the direction of an action. By some linguists, they are still regarded as two separate cases in those languages, although the suffixes are exactly the same for both cases. Other linguists list them separately only for the purpose of separating syntactic cases from locative cases. An example with the ditransitive verb "show" (literally: "make see") is given below:

The dative/lative is also used to indicate possession, as in the example below, because there is no such verb as "to have".

As in the examples above, the dative/lative case usually occurs in combination with another suffix as poss-lative case; this should not be regarded as a separate case, however, as many of the locative cases in Tsez are constructed analytically; hence, they are, in fact, a combination of two case suffixes. See Tsez language for further details.

Verbs of perception or emotion (like "see", "know", "love", "want") also require the logical subject to stand in the dative/lative case. In this example the "pure" dative/lative without its POSS-suffix is used.

Turkish
The dative case (yönelme durumu) in the Turkish language is formed by adding the  -e" or "-a  suffixes to the end of the noun, in accordance with the effected noun's vowel harmony. The word that should be in the dative case can be found as an answer to the questions 'neye?' (to what?), 'kime?' (to whom?) and 'nereye?' (to where?) will lead to find a dative case in a sentence. There are many different uses for the dative case.

The dative also is for objects, usually indirect objects, but sometimes objects that in English would be considered direct:

Güneşin batışına bak.

sun's at-its-sinking look

"Look at the sunset."

The dative case tells whither, that is, the place to which. Thus it has roughly the meaning of the English prepositions "to" and "into", and also "in" when it can be replaced with "into":

Birayı buzdolabına koy.

the-beer into-icebox put

"Put the beer in(to) the fridge."

Dodecahedron

In geometry, a dodecahedron or duodecahedron is any polyhedron  with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid. There are also three regular star dodecahedra, which are constructed as stellations of the convex form. All of these have icosahedral symmetry, order 120.

Some dodecahedra have the same combinatorial structure as the regular dodecahedron (in terms of the graph formed by its vertices and edges), but their pentagonal faces are not regular: The pyritohedron, a common crystal form in pyrite, has pyritohedral symmetry, while the tetartoid has tetrahedral symmetry.

The rhombic dodecahedron can be seen as a limiting case of the pyritohedron, and it has octahedral symmetry. The elongated dodecahedron and trapezo-rhombic dodecahedron variations, along with the rhombic dodecahedra, are space-filling. There are numerous other dodecahedra.

While the regular dodecahedron shares many features with other Platonic solids, one unique property of it is that one can start at a corner of the surface and draw an infinite number of straight lines across the figure that return to the original point without crossing over any other corner.

Regular dodecahedron
The convex regular dodecahedron is one of the five regular Platonic solids and can be represented by its Schläfli symbol {5, 3}.

The dual polyhedron is the regular icosahedron {3, 5}, having five equilateral triangles around each vertex.

The convex regular dodecahedron also has three stellations, all of which are regular star dodecahedra. They form three of the four Kepler–Poinsot polyhedra. They are the small stellated dodecahedron {5/2, 5}, the great dodecahedron {5, 5/2}, and the great stellated dodecahedron {5/2, 3}. The small stellated dodecahedron and great dodecahedron are dual to each other; the great stellated dodecahedron is dual to the great icosahedron {3, 5/2}. All of these regular star dodecahedra have regular pentagonal or pentagrammic faces. The convex regular dodecahedron and great stellated dodecahedron are different realisations of the same abstract regular polyhedron; the small stellated dodecahedron and great dodecahedron are different realisations of another abstract regular polyhedron.

Other pentagonal dodecahedra
In crystallography, two important dodecahedra can occur as crystal forms in some symmetry classes of the cubic crystal system that are topologically equivalent to the regular dodecahedron but less symmetrical: the pyritohedron with pyritohedral symmetry, and the tetartoid with tetrahedral symmetry:

Pyritohedron
A pyritohedron is a dodecahedron with pyritohedral (Th) symmetry. Like the regular dodecahedron, it has twelve identical pentagonal faces, with three meeting in each of the 20 vertices (see figure). However, the pentagons are not constrained to be regular, and the underlying atomic arrangement has no true fivefold symmetry axis. Its 30 edges are divided into two sets – containing 24 and 6 edges of the same length. The only axes of rotational symmetry are three mutually perpendicular twofold axes and four threefold axes.

Although regular dodecahedra do not exist in crystals, the pyritohedron form occurs in the crystals of the mineral pyrite, and it may be an inspiration for the discovery of the regular Platonic solid form. The true regular dodecahedron can occur as a shape for quasicrystals (such as holmium–magnesium–zinc quasicrystal) with icosahedral symmetry, which includes true fivefold rotation axes.

Crystal pyrite
The name crystal pyrite comes from one of the two common crystal habits shown by pyrite (the other one being the cube). In pyritohedral pyrite, the faces have a Miller index of (210), which means that the dihedral angle is 2·arctan(2) ≈ 126.87° and each pentagonal face has one angle of approximately 121.6° in between two angles of approximately 106.6° and opposite two angles of approximately 102.6°. The following formulas show the measurements for the face of a perfect crystal (which is rarely found in nature).

$$\text{Height} = \frac{\sqrt{5}}{2} \cdot \text{Long side}$$

$$\text{Width} = \frac{4}{3} \cdot \text{Long side}$$

$$\text{Short sides} = \sqrt{\frac{7}{12}} \cdot \text{Long side}$$

Cartesian coordinates
The eight vertices of a cube have the coordinates (±1, ±1, ±1).

The coordinates of the 12 additional vertices are ( 0, ±(1 + h), ±(1 − h2) ) , ( ±(1 + h), ±(1 − h2), 0 ) and ( ±(1 − h2), 0, ±(1 + h) ).

h is the height of the wedge -shaped "roof" above the faces of that cube with edge length 2.

An important case is h = $h$ (a quarter of the cube edge length) for perfect natural pyrite (also the pyritohedron in the Weaire–Phelan structure).

Another one is h = $h$ = 0.618... for the regular dodecahedron. See section Geometric freedom for other cases.

Two pyritohedra with swapped nonzero coordinates are in dual positions to each other like the dodecahedra in the compound of two dodecahedra.

Geometric freedom
The pyritohedron has a geometric degree of freedom with limiting cases of a cubic convex hull at one limit of collinear edges, and a rhombic dodecahedron as the other limit as 6 edges are degenerated to length zero. The regular dodecahedron represents a special intermediate case where all edges and angles are equal.

It is possible to go past these limiting cases, creating concave or nonconvex pyritohedra. The endo-dodecahedron is concave and equilateral; it can tessellate space with the convex regular dodecahedron. Continuing from there in that direction, we pass through a degenerate case where twelve vertices coincide in the centre, and on to the regular great stellated dodecahedron where all edges and angles are equal again, and the faces have been distorted into regular pentagrams. On the other side, past the rhombic dodecahedron, we get a nonconvex equilateral dodecahedron with fish-shaped self-intersecting equilateral pentagonal faces.

Tetartoid
A tetartoid (also tetragonal pentagonal dodecahedron, pentagon-tritetrahedron, and tetrahedric pentagon dodecahedron) is a dodecahedron with chiral tetrahedral symmetry (T). Like the regular dodecahedron, it has twelve identical pentagonal faces, with three meeting in each of the 20 vertices. However, the pentagons are not regular and the figure has no fivefold symmetry axes.

Although regular dodecahedra do not exist in crystals, the tetartoid form does. The name tetartoid comes from the Greek root for one-fourth because it has one fourth of full octahedral symmetry, and half of pyritohedral symmetry. The mineral cobaltite can have this symmetry form.

Abstractions sharing the solid's topology and symmetry can be created from the cube and the tetrahedron. In the cube each face is bisected by a slanted edge. In the tetrahedron each edge is trisected, and each of the new vertices connected to a face center. (In Conway polyhedron notation this is a gyro tetrahedron.)

Cartesian coordinates
The following points are vertices of a tetartoid pentagon under tetrahedral symmetry:
 * (a, b, c); (−a, −b, c); (−$h$, −$84$, $4h$); (−c, −a, b); (−$3h$, $1⁄2$, $1⁄φ$),

under the following conditions:
 * 0 ≤ a ≤ b ≤ c,
 * n = a2c − bc2,
 * d1 = a2 − ab + b2 + ac − 2bc,
 * d2 = a2 + ab + b2 − ac − 2bc,
 * nd1d2 ≠ 0.

Geometric freedom
The regular dodecahedron is a tetartoid with more than the required symmetry. The triakis tetrahedron is a degenerate case with 12 zero-length edges. (In terms of the colors used above this means, that the white vertices and green edges are absorbed by the green vertices.)

Dual of triangular gyrobianticupola
A lower symmetry form of the regular dodecahedron can be constructed as the dual of a polyhedron constructed from two triangular anticupola connected base-to-base, called a triangular gyrobianticupola. It has D3d symmetry, order 12. It has 2 sets of 3 identical pentagons on the top and bottom, connected 6 pentagons around the sides which alternate upwards and downwards. This form has a hexagonal cross-section and identical copies can be connected as a partial hexagonal honeycomb, but all vertices will not match.
 * Dual_triangular_gyrobianticupola.png

Rhombic dodecahedron
The rhombic dodecahedron is a zonohedron with twelve rhombic faces and octahedral symmetry. It is dual to the quasiregular cuboctahedron (an Archimedean solid) and occurs in nature as a crystal form. The rhombic dodecahedron packs together to fill space.

The rhombic dodecahedron can be seen as a degenerate pyritohedron where the 6 special edges have been reduced to zero length, reducing the pentagons into rhombic faces.

The rhombic dodecahedron has several stellations, the first of which is also a parallelohedral spacefiller.

Another important rhombic dodecahedron, the Bilinski dodecahedron, has twelve faces congruent to those of the rhombic triacontahedron, i.e. the diagonals are in the ratio of the golden ratio. It is also a zonohedron and was described by Bilinski in 1960. This figure is another spacefiller, and can also occur in non-periodic spacefillings along with the rhombic triacontahedron, the rhombic icosahedron and rhombic hexahedra.

Other dodecahedra
There are 6,384,634 topologically distinct convex dodecahedra, excluding mirror images—the number of vertices ranges from 8 to 20. (Two polyhedra are "topologically distinct" if they have intrinsically different arrangements of faces and vertices, such that it is impossible to distort one into the other simply by changing the lengths of edges or the angles between edges or faces.)

Topologically distinct dodecahedra (excluding pentagonal and rhombic forms)
 * Uniform polyhedra:
 * Decagonal prism – 10 squares, 2 decagons, D10h symmetry, order 40.
 * Pentagonal antiprism – 10 equilateral triangles, 2 pentagons, D5d symmetry, order 20
 * Johnson solids (regular faced):
 * Pentagonal cupola – 5 triangles, 5 squares, 1 pentagon, 1 decagon, C5v symmetry, order 10
 * Snub disphenoid – 12 triangles, D2d, order 8
 * Elongated square dipyramid – 8 triangles and 4 squares, D4h symmetry, order 16
 * Metabidiminished icosahedron – 10 triangles and 2 pentagons, C2v symmetry, order 4
 * Congruent irregular faced: (face-transitive)
 * Hexagonal bipyramid – 12 isosceles triangles, dual of hexagonal prism, D6h symmetry, order 24
 * Hexagonal trapezohedron – 12 kites, dual of hexagonal antiprism, D6d symmetry, order 24
 * Triakis tetrahedron – 12 isosceles triangles, dual of truncated tetrahedron, Td symmetry, order 24
 * Other less regular faced:
 * Hendecagonal pyramid – 11 isosceles triangles and 1 regular hendecagon, C11v, order 11
 * Trapezo-rhombic dodecahedron – 6 rhombi, 6 trapezoids – dual of triangular orthobicupola, D3h symmetry, order 12
 * Rhombo-hexagonal dodecahedron or elongated Dodecahedron – 8 rhombi and 4 equilateral hexagons, D4h symmetry, order 16
 * Truncated pentagonal trapezohedron, D5d, order 20, topologically equivalent to regular dodecahedron

Practical usage
Armand Spitz used a dodecahedron as the "globe" equivalent for his Digital Dome planetarium projector, based upon a suggestion from Albert Einstein.

Darwin, Northern Territory

Darwin (Larrakia: Garramilla) is the capital city of the Northern Territory, Australia. The city has nearly 53% of the Northern Territory's population, with 139,902 at the 2021 census. It is the smallest, wettest, and most northerly of the Australian capital cities and serves as the Top End's regional centre.

Darwin's proximity to Southeast Asia makes it a key link between Australia and countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin and extends southerly across central Australia through Tennant Creek and Alice Springs, concluding in Port Augusta, South Australia. The city is built upon a low bluff overlooking Darwin Harbour. Darwin's suburbs begin at Lee Point in the north and stretch to Berrimah in the east. The Stuart Highway extends to Darwin's eastern satellite city of Palmerston and its suburbs.

The Darwin region, like much of the Top End, has a tropical climate, with a wet and dry season. A period known locally as "the build up" leading up to Darwin's wet season sees temperature and humidity increase. Darwin's wet season typically arrives in late November to early December and brings with it heavy monsoonal downpours, spectacular lightning displays, and increased cyclone activity. During the dry season, the city has clear skies and mild sea breezes from the harbour.

The Larrakia people are the traditional owners of the Darwin area and Aboriginal people are a significant proportion of the population. On 9 September 1839, HMS Beagle sailed into Darwin Harbour during its survey of the area. John Clements Wickham named the region "Port Darwin" in honour of their former shipmate Charles Darwin, who had sailed with them on the ship's previous voyage. The settlement there became the town of Palmerston in 1869, but was renamed Darwin in 1911. The city has been almost entirely rebuilt four times, following devastation caused by a cyclone in 1897, another one in 1937, Japanese air raids during World War II, and Cyclone Tracy in 1974.

Indigenous history
The Aboriginal people of the Larrakia language group are the traditional custodians and earliest known inhabitants of the greater Darwin area. Their name for the area is Garramilla, pronounced and meaning "white stone", referring to the colour of rock and sea cliffs found in the area. They had trading routes with Southeast Asia (see Macassan contact with Australia) and imported goods from as far afield as South and Western Australia. Established songlines penetrated throughout the country, allowing stories and histories to be told and retold along the routes. The extent of shared songlines and history of multiple clan groups within this area is contestable.

Pre-20th century
The Dutch visited Australia's northern coastline in the 1600s and landed on the Tiwi Islands only to be repelled by the Tiwi peoples. The Dutch created the first European maps of the area. This accounts for the Dutch names in the area, such as Arnhem Land and Groote Eylandt. During this period, Dutch explorers named the region around Darwin—sometimes including nearby Kimberley—variations of "Van Diemen's Land", after the VOC governor-general Anthony van Diemen. This should not be confused with the more general and prolonged use of the same name for Tasmania.

The first British person to see Darwin harbour appears to have been Lieutenant John Lort Stokes of HMS Beagle on 9 September 1839. The ship's captain, Commander John Clements Wickham, named the port after Charles Darwin, the British naturalist who had sailed with him when he served as first lieutenant on the earlier second expedition of the Beagle. In 1863, the Northern Territory was transferred from New South Wales to South Australia. In 1864 South Australia sent B. T. Finniss north as Government Resident to survey and found a capital for its new territory. Finniss chose a site at Escape Cliffs, near the entrance to Adelaide River, about 60 km northeast of the modern city. This attempt was short-lived, and the settlement abandoned by 1865. On 5 February 1869, George Goyder, the Surveyor-General of South Australia, established a small settlement of 135 people at Port Darwin between Fort Hill and the escarpment. Goyder named the settlement Palmerston after British Prime Minister Lord Palmerston. In 1870, the first poles for the Overland Telegraph were erected in Darwin, connecting Australia to the rest of the world. The discovery of gold by employees of the Australian Overland Telegraph Line digging holes for telegraph poles at Pine Creek in the 1880s spawned a gold rush, which further boosted the colony's development. In February 1872 the brigantine Alexandra was the first private vessel to sail from an English port directly to Darwin, carrying people many of whom were coming to recent gold finds. In early 1875 Darwin's white population had grown to approximately 300 because of the gold rush. On 17 February 1875 the SS Gothenburg left Darwin en route for Adelaide. The approximately 88 passengers and 34 crew (surviving records vary) included government officials, circuit-court judges, Darwin residents taking their first furlough, and miners. While travelling south along the north Queensland coast, the Gothenburg encountered a cyclone-strength storm and was wrecked on a section of the Great Barrier Reef. Only 22 men survived, while between 98 and 112 people perished. Many passengers who perished were Darwin residents, and news of the tragedy severely affected the small community, which reportedly took several years to recover.

In the 1870s, relatively large numbers of Chinese settled at least temporarily in the Northern Territory; many were contracted to work the goldfields and later to build the Palmerston to Pine Creek railway. By 1888 there were 6,122 Chinese in the Northern Territory, mostly in or around Darwin. The early Chinese settlers were mainly from Guangdong Province. The Chinese community established Darwin Chinatown. At the end of the 19th century, anti-Chinese feelings grew in response to the 1890s economic depression, and the White Australia policy meant many Chinese left the territory. But some stayed, became British subjects, and established a commercial base in Darwin.

Early 20th century
The Northern Territory was initially settled and administered by South Australia, until its transfer to the Commonwealth in 1911. In the same year, the city's official name changed from Palmerston to Darwin.

The period between 1911 and 1919 was filled with political turmoil, particularly with trade union unrest, which culminated on 17 December 1918. Led by Harold Nelson, some 1,000 demonstrators marched to Government House at Liberty Square in Darwin, where they burnt an effigy of the Administrator of the Northern Territory, John Gilruth, and demanded his resignation. The incident became known as the Darwin Rebellion. Their grievances were against the two main Northern Territory employers: Vestey's Meatworks and the federal government. Both Gilruth and the Vestey company left Darwin soon afterward.

On 18 October 1918, during the Spanish flu pandemic, the SS Mataram sailing from Singapore with infectious diseases arrived in Darwin.

In 1931, the 17 remaining patients from the leprosarium at Cossack, Western Australia were moved to Darwin, after it closed down. It was at a time when many Aboriginal people who were thought to have leprosy or other infectious diseases were sent to lock hospitals and leprosariums under the Aborigines Act 1905, which gave the Chief Protector of Aborigines powers to arrest and send any Indigenous person suspected of having a range of diseases to one of these institutions.

Around 10,000 Australian and other Allied troops arrived in Darwin at the outset of World War II to defend Australia's northern coast. On 19 February 1942 at 0957, 188 Japanese warplanes attacked Darwin in two waves. It was the same fleet that had bombed Pearl Harbor, though considerably more bombs were dropped on Darwin than on Pearl Harbor. The attack killed at least 243 people and caused immense damage to the town, airfields, and aircraft. These were by far the most serious attacks on Australia in time of war, in terms of fatalities and damage. They were the first of many raids on Darwin.

Darwin Chinatown which lay within the heart of Darwin was razed to the ground by the Japanese bombing and was never rebuilt. Northern Territory administrator Aubrey Abbott wanted to eliminate the Chinese community and forcibly seized their land as it was considered prime real estate.

Darwin was further developed after the war, with sealed roads constructed connecting the region to Alice Springs to the south and Mount Isa to the southeast, and Manton Dam built in the south to provide the city with water. On Australia Day (26 January) 1959, Darwin was granted city status.

1970–present
On 25 December 1974, Darwin was struck by Cyclone Tracy, which killed 71 people and destroyed over 70% of the city's buildings, including many old stone buildings such as the Palmerston Town Hall, which could not withstand the lateral forces the winds generated. After the disaster, 30,000 of the population of 46,000 were evacuated in the biggest airlift in Australia's history. The town was rebuilt with newer materials and techniques during the late 1970s by the Darwin Reconstruction Commission, led by former Brisbane Lord mayor Clem Jones. A satellite city of Palmerston was built 20 km east of Darwin in the early 1980s.

On 17 September 2003, the Adelaide–Darwin railway was completed, with the opening of the Alice Springs–Darwin standard gauge line.

Aviation history
Darwin hosted many of aviation's early pioneers. On 10 December 1919, Captain Ross Smith and his crew landed in Darwin and won a £10,000 prize from the Australian government for completing the first flight from London to Australia in under 30 days. Smith and his crew flew a Vickers Vimy, G-EAOU, and landed on an airstrip that has become Ross Smith Avenue.

Other aviation pioneers include Amy Johnson, Amelia Earhart, Sir Charles Kingsford Smith and Bert Hinkler. The original QANTAS Empire Airways Ltd Hangar, a registered heritage site, was part of the original Darwin Civil Aerodrome in Parap and is now a museum that still bears scars from the bombing of Darwin during World War II.

Darwin was home to Australian and U.S. pilots during the war, with airstrips built in and around Darwin. Today Darwin provides a staging ground for military exercises.

Darwin was a compulsory stopover and checkpoint in the London-to-Melbourne Centenary Air Race in 1934. The official name of the race was the MacRobertson Air Race. Winners of the race were Tom Campbell Black and C. W. A. Scott.

The following is an excerpt from Time magazine, 29 October 1934:

"Third Day. Biggest sensation of the race came just before dawn on the third day, when burly Lieutenant Scott and dapper Captain Black flew their scarlet Comet into Darwin. They had covered the last 300 mi over water on one motor, risked death landing on a field made soggy by the first rain in seven months. Said sandy-haired Lieutenant Scott: 'We've had a devil of a trip.' But they had flown 9000 mi in two days, had broken the England to Australia record of 162 hr. in the unbelievable time of 52hr. 33 min., were only 2000 mi from their goal at Melbourne."

The Darwin Aviation Museum is about 8 km from the city centre on the Stuart Highway and is one of only three places outside the United States where a B-52 bomber (on permanent loan from the United States Air Force) is on public display.

Geography
Darwin is a coastal city, situated along the western shoreline of the Northern Territory. The water meets the land from the Beagle Gulf, which extends out into the Timor Sea. The central business district occupies a low bluff overlooking Darwin Harbour to the south, beyond which lie East Arm, Middle Arm, Northern Territory, and, across the gulf, West Arm. Middle Arm has an industrial precinct on the peninsula, which is being promoted as a sustainable development area that will include plants for industries such as low-emission petrochemicals, renewable hydrogen, and carbon capture storage. The city is flanked by Frances Bay to the east and Cullen Bay to the west.

The rest of the city is relatively flat and low-lying, and areas bordering the coast are home to recreational reserves, extensive beaches, and excellent fishing.

City and suburbs
Darwin and its suburbs spread in an approximately triangular shape, with the older southwestern suburbs—and the city itself—forming one corner, the newer northern suburbs another, and the eastern suburbs, progressing towards Palmerston, forming the third.

The older part of Darwin is separated from the newer northern suburbs by Darwin International Airport and RAAF Base Darwin. Palmerston is a satellite city 20 km east of Darwin that was established in the 1980s and is one of Australia's fastest-growing municipalities. Darwin's rural areas, including Howard Springs, Humpty Doo and Berry Springs, are experiencing strong growth. Darwin's central business district (CBD) is bounded by Daly Street in the northwest, McMinn Street in the northeast, Mitchell Street on the southwest, and Bennett Street on the southeast. The CBD has been the focus of a number of major projects, such as the billion-dollar redevelopment of the Stokes Hill wharf waterfront area, including a convention centre with seating for 1,500 people and approximately 4000 m2 of exhibition space. The developers announced that this includes hotels, residential apartments, and public space. The city's main industrial areas are along the Stuart Highway toward Palmerston, centred on Winnellie. The area'a largest shopping precinct is Casuarina Square.

The most expensive residential areas stand along the coast in suburbs such as the marina of Cullen Bay, Larrakeyah, Bayview and Brinkin. These low-lying regions are at risk during cyclones and higher tides, but adequate drainage and stringent building regulations have reduced the potential damage to buildings or injury to residents. The inner northern suburbs are home to lower-income households, although low-income Territory Housing units are scattered throughout the metropolitan area. The suburb of Lyons was part of a multi-stage land release and development in the Northern Suburbs; planning, development and construction took place from 2004 to 2009. More recent developments near Lyons subdivision includes the suburb of Muirhead.

Climate
Darwin has a tropical savanna climate (Köppen Aw) with distinct wet and dry seasons, and the average maximum temperature is similar year round. The Australian Building Codes Board classifies it as Climate Zone 1 based on its very humid summers and warm winters. The dry season runs from about May to September, during which nearly every day is sunny, and afternoon relative humidity averages around 30%.

The driest period of the year, seeing about 5 mm of monthly rainfall on average, is between May and September. In the coolest months, June and July, the daily minimum temperature may dip as low as 14 °C, but very rarely lower, and a temperature lower than 10 °C has never been recorded in the city centre. Outer suburbs away from the coast occasionally record temperatures as low as 5 °C in the dry season. For a 147‑day period during the 2012 dry season, from 5 May to 29 September, Darwin recorded no precipitation. Prolonged periods of no precipitation are common in the dry season in Northern Australia (particularly in the Northern Territory and northern regions of Western Australia), although a no-rainfall event of this extent is rare. The 3pm dewpoint average in the wet season is around 24.0 °C.

Extreme temperatures at the Darwin Post Office Station have ranged from 40.4 °C on 17 October 1892 to 13.4 °C on 25 June 1891; extreme temperatures at the Darwin Airport station (which is farther from the coast and routinely records cooler temperatures than the post office station, which is in Darwin's CBD) have ranged from 38.9 °C on 18 October 1982 to 10.4 °C on 29 July 1942. The highest minimum temperature on record is 30.7 °C on 18 January 1928 for the post office station and 29.7 °C on both 25 November 1987 and 17 December 2014 for the airport station. The lowest maximum temperature on record is 18.4 °C on 3 June 1904 for the post office station and 21.1 °C on 14 July 1968 for the airport station.

The wet season is associated with tropical cyclones and monsoon rains. Most rainfall occurs between December and March (the summer), when thunderstorms are common and afternoon relative humidity averages over 70 percent during the wettest months. It does not rain every day during the wet season, but most days have plentiful cloud cover; January averages under six hours of bright sunshine daily. Darwin's highest daily rainfall verified by the Bureau of Meteorology is 367.6 mm, which fell when Cyclone Carlos bore down on the Darwin area on 16 February 2011. February 2011 was also Darwin's wettest month ever recorded, with 1110.2 mm at the airport.

The hottest months are October and November, just before the onset of the main rain season. The temperature is usually below 35 °C, but the heat index sometimes rises above 45 °C, because of humidity levels that most find uncomfortable. Because of its long dry season, Darwin has the second-highest average daily hours of sunshine (8.4) of any Australian capital, with the most sunshine from April to November; only Perth, Western Australia, averages more (8.8). The sun passes directly overhead in mid-October and mid-February.

The average temperature of the sea ranges from 25.8 C in July to 31.5 C in December.

Darwin occupies one of the most lightning-prone areas in Australia. On 31 January 2002 an early-morning squall line produced over 5,000 cloud-to-ground lightning strikes within a 60 km radius of Darwin alone—about three times the amount of lightning that Perth experiences on average in an entire year.

Ancestry and immigration
Darwin's population changed after the Second World War. Like many other Australian cities, Darwin experienced influxes from Europe, with significant numbers of Italians and Greeks during the 1960s and 1970s. It also began to experience an influx from other European countries, which included the Dutch, Germans, and many others. A significant proportion of Darwin's residents are recent immigrants from Asia, including the peoples of East Timor.

At the 2016 census, the most commonly nominated ancestries were: • Australian (37.4%)

• English (32.7%)

• Irish (11.1%)

• Scottish (8.8%)

• Indigenous (8.7%)

• German (5%)

• Filipino (4.8%)

• Chinese (4.5%)

• Greek (3.2%)

• Indian (2.8%)

• Italian (2.6%)

• Dutch (1.5%)

• Indonesian (1.1%)

• New Zealander (1.1%)

38.3% of the population at the 2016 census was born overseas. The five largest groups of overseas-born were from the Philippines (3.6%), England (3.1%), New Zealand (2.1%), India (2%) and Greece (0.9%).

8.7% of the population, or 11,960 people, identified as Indigenous Australians (Aboriginal Australians and/or Torres Strait Islanders) in 2016. This is the largest proportion of any Australian capital city.

Language
At the 2016 census, 58% of the population spoke only English at home. Other languages spoken at home include Tagalog (3.7%), Greek (3.5%), Mandarin (2.0%), Nepali (1.2%), Indonesian (1.0%), Australian Aboriginal languages (1.0%), Malayalam (0.9%), Vietnamese (0.8%), Cantonese (0.7%), Italian (0.6%), Portuguese (0.5%, mostly spoken by Timorese), and Tamil (0.5%).

Age
In 2011, the Darwin population averaged 33 years old (compared to the national average of around 37), to a large extent because of the military presence and because many people opt to retire elsewhere.

Religion
, Christianity had the most adherents in Darwin, with 56,613 followers accounting for 49.5 percent of the population. The largest denominations of Christianity are Roman Catholicism (24,538 or 21.5 percent), Anglicanism (14,028 or 12.3 percent) and Greek Orthodoxy (2,964 or 2.6 percent). Buddhists, Muslims, Hindus and Jews account for 3.2 percent of Darwin's population. There were 26,695 or 23.3 percent of people professing no religion.

Law and government
The Darwin City Council (incorporated under the Northern Territory Local Government Act 1993) governs the City of Darwin, which takes in the CBD and the suburbs. The city has been governed by a city council form of government since 1957. The council consists of 13 elected members, the lord mayor, and 12 aldermen.

The City of Darwin electorate is organised into four electoral units or wards. The wards are Chan, Lyons, Richardson, and Waters. The constituents of each ward are directly responsible for electing three aldermen. Constituents of all wards are directly responsible for electing the Lord Mayor of Darwin. Since the August 2017 council elections, the mayor has been Kon Vatskalis.

The rest of the Darwin area is divided into two local government areas—the Palmerston City Council and the Shire of Coomalie. These areas have elected councils that are responsible for functions delegated to them by the Northern Territory Government, such as planning and garbage collection.

The Legislative Assembly of the Northern Territory convenes in Darwin in the Northern Territory Parliament House. Government House, the official residence of the Administrator of the Northern Territory, is on the Esplanade.

Darwin is split between nine electoral divisions in the Legislative Assembly—Port Darwin, Fannie Bay, Fong Lim, Nightcliff, Sanderson, Johnston, Casuarina, Wanguri, and Karama. Historically, Darwin voters elected Country Liberal Party members, but since the turn of the 21st century, voters have often selected Labor members, particularly in the more diverse northern section; as of the 2020 Northern Territory general election, all of Darwin's nine Legislative Assembly electoral divisions are held by Labor, with Labor also holding both the Northern Territory's federal electorates, Solomon and Lingiari.

Also on the Esplanade is the Supreme Court of the Northern Territory. Darwin has a Magistrate's Court on the corner of Cavenagh and Bennett streets, close to the Darwin City Council Chambers.

Crime
Darwin's police force are members of the Northern Territory Police, under the NT Police Darwin Metropolitan Command. The Darwin urban centre includes Darwin City and the associated suburbs from Buffalo Creek, Berrimah, and East Arm westwards, representing around 35% of the Northern Territory's population. Palmerston urban centre closely approximates the Palmerston Local Government Area, and represents approximately 13% of the Northern Territory's population.

Darwin has had a history of alcohol abuse and violent crime, with 6,000 assaults in 2009, of which 350 resulted in broken jaws and noses—more than anywhere else in the world, according to the Royal Darwin Hospital.

Mitchell Street, with its numerous pubs, clubs and other entertainment venues, was one of the areas policed by the CitySafe Unit, officially launched by the NT Chief Minister Paul Henderson on 25 February 2009. It was credited with success in tackling alcohol abuse linked to crime, and the NT police were looking at establishing a specialist licensing enforcement unit in 2010.

The First Response Patrol, run by Larrakia Nation, which helps move homeless Indigenous women out of dangerous situations, was credited with the decline in sexual assaults in 2009. The service operates every day from 5am to 2am.

Recent trends
In the 10 months between 1 October 2018, the date that the alcohol floor price and various other measures were imposed by the NT government following the Riley Review, and 31 July 2019, alcohol-related assaults dropped by 16% and domestic violence by 9% in the Darwin area.

The rate of offending in most categories of crime dropped in the Darwin urban area between 2018 and 2019, with the notable exceptions of motor vehicle theft and break-ins (both up about 12%). Apart from sexual assault, which rose from 21 to 46, all other categories of crime declined in Palmerston.

Economy
The two largest economic sectors are mining and tourism. Given its location, Darwin serves as a gateway for Australian travellers to Asia. Mining and energy industry production exceeds $2.5 billion per annum. The most important mineral resources are gold, zinc, and bauxite, along with manganese and many others. The energy production is mostly off-shore with oil and natural gas from the Timor Sea, although there are significant uranium deposits near Darwin. Tourism employs 8% of Darwin residents and is expected to grow as domestic and international tourists now spend time in Darwin during the wet and dry seasons. Federal spending is also a major contributor to the local economy. Darwin's importance as a port is expected to grow, due to the increased exploitation of petroleum in the nearby Timor Sea and to the completion of the railway link and continued expansion in trade with Asia. During 2005, a number of major construction projects started in Darwin. One is the redevelopment of the Wharf Precinct, which includes a large convention and exhibition centre, apartment housing including Outrigger Pandanas and Evolution on Gardiner, retail and entertainment outlets including a large wave pool and safe swimming lagoon. The Chinatown project has also started with plans to construct Chinese-themed retail and dining outlets.

Tourism
Tourism is one of Darwin's largest industries and a major employment sector for the Northern Territory. In 2005–2006, 1.38 million people visited the Northern Territory. They stayed for 9.2 million nights and spent over $1.5 billion. The tourism industry directly employed 8,391 Territorians in June 2006, and, when indirect employment is included, tourism typically accounts for more than 14,000 jobs across the Territory.

Darwin is a hub for tours to Kakadu National Park, Litchfield National Park and Katherine Gorge. The year is traditionally divided into the wet and dry seasons, but there are up to six traditional seasons in Darwin. It is warm and sunny from May to September. Humidity rises during the green season, from October to April, bringing thunderstorms and monsoonal rains that rejuvenate the landscape. Tourism is largely seasonal, with most tourists visiting during the cooler dry season, from April to September.

Military
The military presence in both Darwin and the wider Northern Territory is a substantial source of employment. On 16 November 2011, Prime Minister Julia Gillard and President Barack Obama announced that the United States would station troops in Australia for the first time since World War II. The agreement between the U.S. and Australia would involve a contingent of 250 Marines arriving in Darwin in 2012, with the total number rising to a maximum of 2,500 troops by 2017 on six-month rotations as well as a supporting air element including F-22 Raptors, F-35 Joint Strike Fighters and KC-135 refuellers. China and Indonesia have expressed concern about the decision. Some analysts have argued that an expanded U.S. presence could pose a threat to security. Gillard announced that the first 200 U.S. Marines had arrived in Darwin from Hawaii on 3 April 2012. In 2013, further news of other expansion vectors aired in U.S. media, with no comment or confirmation from Australian authorities. The agreement between the two governments remains hidden from public scrutiny. Marine numbers based in Darwin increased to more than 1,150 by 2014. In a 2019 telephone survey of local residents, 51% of respondents had positive feelings about the U.S. troop presence, with 6% responding negatively. In late 2021, the U.S. Department of Defense signed a contract to create a 300 e6l fuel storage facility at East Arm.

Darwin hosts biennial multi-nation exercises named "Pitch Black"; in 2014 this involved military personnel from Australia, New Zealand, Singapore, Thailand, United Arab Emirates, and the United States.

Education
Education is overseen territory-wide by the Department of Education and Training (DET), whose role is to continually improve education outcomes for all students, with a focus on Indigenous students.

Preschool, primary and secondary
Darwin is served by a number of public and private schools that cater to local and overseas students. Over 16,500 primary and secondary students are enrolled in schools in Darwin, with 10,524 students attending primary education, and 5,932 students attending secondary education. Over 12,089 students are enrolled in government schools, and 2,124 in independent schools. There were 9,764 students attending schools in the City of Darwin area. 6,045 students attended primary schools and 3,719 attended secondary schools. Over 7,161 students are enrolled in government schools and 1,108 in independent schools. There are over 35 primary and pre-schools and 12 secondary schools, including both government and non-government. Most schools in the city are secular, but there are a small number of Catholic and Lutheran institutions. Students intending to complete their secondary education work toward either the Northern Territory Certificate of Education, the Victorian Certificate of Education, or the Victorian Certificate of Applied Learning (the latter two are offered only at Haileybury Rendall School ). Until the sale and restructuring of Kormilda College in 2018, it was the only school to offer the International Baccalaureate in the Northern Territory.

Schools have been restructured into Primary, Middle, and High schools since the beginning of 2007.

Tertiary and vocational
Darwin's largest university is Charles Darwin University, the Northern Territory's central provider of tertiary education. It has both vocational and academic courses, acting as both a university and an Institute of TAFE. More than 5,500 students are enrolled in tertiary and further education courses.

Darwin is also home to several private vocational colleges, including Alana Kaye College and Latitude College.

Architecture
As Darwin was destroyed by cyclones several times and suffered severe bomb damage during World War II, few historic buildings remain in town. The Administrator's Office dating from 1883 was used as a law court and as a police station and was only slightly damaged by bombs, but in 1974, the cyclone completely destroyed it. In 1979, it was decided to rebuild, and the reconstruction was finished in 1981. The building houses government offices today. Opposite the building, Survivors Lookout offers a view of the marina. In a park in the south of the CBD, the ruin of the Town Hall built in 1883 and destroyed by the cyclone in 1974 can be seen. Browns Mart is a stone building dating from 1880 opposite the park. Browns Mart was originally used in many different activities including commerce, storage, shipping and insurance agency, mining exchange and meetings of local organisations but it was transformed into a theatre.

One of Darwin's most prominent buildings is the Chinese Temple, which was founded in 1887 and damaged by cyclones in 1897 and in 1937. It was severely damaged by bombs in 1942 and rebuilt after the war. On 24 December 1974 the cyclone completely destroyed it. Reconstruction was completed in 1978.

There are various modern churches in Darwin. St Mary's Star of the Sea Roman Catholic Cathedral was inaugurated in 1962. Christ Church Anglican Cathedral was rebuilt in 1977 after being severely damaged by bombs in 1942 and destroyed by Cyclone Tracy in 1974. The Uniting Memorial Church was built in 1960.

Arts and culture
The Darwin Symphony Orchestra was assembled in 1989 and has performed throughout the Territory. The Darwin Theatre Company is a locally produced professional theatre production company, performing locally and nationally. The Darwin Entertainment Centre is the city's main concert venue and hosts theatre and orchestral performances. Other theatres include the Darwin Convention Centre, which opened in July 2008. The Darwin Convention Centre is part of the $1.1 billion Darwin Waterfront project.

The Northern Territory Museum and Art Gallery (MAGNT) in Darwin gives an overview of the history of the area, including exhibits on Cyclone Tracy and the boats of the Pacific Islands. The MAGNT also organises the annual Telstra National Aboriginal and Torres Strait Islander Art Award, the longest-running Indigenous art award in Australia. The MAGNT also manages the Defence of Darwin Experience, a multi-media installation that tells the story of the Japanese air raids on Darwin during World War II.

The NT Dance Company is led by choreographer Gary Lang, who has been artistic director since 2012. Lang previously taught at many leading dance companies, including Bangarra Dance Theatre, after studying dance at NAISDA in Sydney and working as a dancer for years. The company has a strong focus on culture, and also works with disadvantaged young Indigenous people.

Local and visiting bands can be heard at venues including the Darwin Entertainment Centre, The Vic Hotel, Happy Yess, and Brown's Mart. Artists such as Jessica Mauboy and The Groovesmiths call Darwin home.

The multiculturalism of Darwin has helped make Southeast Asian noodle broth laksa the city's favourite meal.

Other entertainment
Weekly markets include the popular Mindil Beach Sunset Market (Thursdays and Sundays during the dry season); Parap Market; Nightcliff Market; and Rapid Creek market.

Darwin's only casino opened in 1979 as the Don Casino, operating out of the Don Hotel on Cavenagh Street. The present site of the hotel and casino on Darwin's Mindil Beach opened in 1983, at which point gambling operations ceased at the Don Hotel and resumed at the newly built facilities. The new hotel and casino was named Mindil Beach Casino until 1985, when the name changed to the Diamond Beach Hotel Casino. Upon its acquisition by MGM Grand the hotel was rebranded as the MGM Grand Darwin, before it changed to Skycity Darwin after Skycity Entertainment Group purchased the hotel in 2004.

Mitchell Street in the central business district is lined with nightclubs, takeaways, and restaurants. This is the city's entertainment hub. There are several smaller theatres, three cinema complexes (CBD, Casuarina, and Palmerston), and the Deckchair Cinema. An open-air cinema operates through the dry season, from April to October, screening independent and arthouse films.

Beaches
During the months of October–May the sea contains deadly box jellyfish, known locally as stingers or sea wasps. Saltwater crocodiles are common in all waterways surrounding Darwin and are occasionally found in Darwin Harbour and on local beaches. An active trapping program is carried out by the NT Government to limit numbers of crocodiles within the Darwin urban waterway area.

The city has many kilometres of beaches, including the Casuarina Beach and renowned Mindil Beach, home of the Mindil Beach markets. Darwin City Council has designated an area of Casuarina Beach as a free beach, which has been designated as a nudist beach area since 1976.

Bundilla Beach was formerly named Vesteys Beach, as it was one of the beaches overlooked by Vestey's Meatworks, which existed from 1914 to 1920 and was involved in the Darwin rebellion. In March 2021, the beach was formally renamed Bundilla Beach, the name by which it had long been known to the traditional owners, the Larrakia people.

The Darwin Surf Life Saving Club operates longboats and surf skis and provides events and lifesaving accreditations.

Lake Alexander is a man-made swimming lake at East Point Reserve.

Fishing
Fishing is a popular recreation among Darwin locals. Visitors fish for the barramundi, an iconic fish in the region. This fish thrives in the Daly River, Moyle River, Roper River, Anson Bay,  Mary River,  and South and East Alligator River. Blue-water fishing is also available off the coast of Darwin; Spanish mackerel, black jewfish, queenfish, and snapper are found in the area.

Parks and gardens
Darwin has extensive parks and gardens. These include the George Brown Darwin Botanic Gardens, East Point Reserve, Casuarina Coastal Reserve, Charles Darwin National Park, Knuckey Lagoons Conservation Reserve, Leanyer Recreation Park, the Nightcliff Foreshore, Bicentennial Park and the Jingili Water Gardens.

Wildlife
Darwin is a popular bird-watching site, with locations such as the George Brown Darwin Botanic Gardens, East Point Reserve, Buffalo Creek, Leanyer Ponds, and Knuckey Lagoon. Slightly further from the city is one of the best birding sites in the country, Fogg Dam Conservation Reserve.

Some species of native mammals are more abundant in Darwin than in the surrounding native forest and woodland ecosystems of the region, including the common brushtail possum and black-footed tree-rat. This is likely due to the presence of well-watered gardens and parks, the absence of frequent fires, and the availability of denning sites (e.g. the roofs of houses).

Darwin is also home to many species of frogs and reptiles. There are more species of snake in Darwin than any other Australian capital city, with 34 non-marine snake species found in the region, of which 23 have been recorded by professional snake catchers in Darwin itself. Fortunately for the citizens of Darwin, a far smaller proportion of these snakes are highly venomous than is typically found in other cities, due to the low numbers of front-fanged elapid species and dominance of relatively harmless pythons and colubrid species. Of the 23 more regularly encountered snake species in Darwin, it seems that species with broader habitat and dietary preferences, as well as a penchant for arboreality, are associated with more frequent human–snake interactions. Shifts in snake behaviour or movement also occur throughout the year, with species specific differences in abundance and occurrence in certain months.

Sports
The Marrara Sports Complex near the airport has stadiums for Australian rules (TIO Stadium), cricket, rugby league, football, basketball (and indoor court sports), athletics and field hockey. Every two years since 1991 (excluding 2003 due to the SARS outbreak), Darwin has hosted the Arafura Games, a major regional sporting event. In July 2003, the city hosted its first international test cricket match between Australia and Bangladesh, followed by Australia and Sri Lanka in 2004.

Australian rules is played all year round and the Territory's premier league competition, the Northern Territory Football League is based in Darwin. Australian Football League clubs generally sell a handful of games to the Northern Territory each year, some of which are played at Marrara Oval. Darwin is part of a bid for a Northern Territory AFL license for proposed entry into the competition by 2028 at the earliest. The Darwin based Indigenous All-Stars have participated in the AFL pre-season competition. In 2003, a record crowd of 17,500 attended a pre-season game between the All-Stars and Carlton Football Club at Marrara.

Rugby League and Rugby Union club competitions are played in Darwin each year, organised by the NTRL and NTRU respectively. The Darwin Hottest Sevens in the World tournament is hosted in Darwin each January, with Rugby Sevens club teams from countries including Australia, New Zealand, Papua New Guinea, Malaysia, and Singapore competing. Darwin's Hottest 7s is the richest Rugby 7s tournament in the Southern Hemisphere.

Darwin hosts a round of the Supercars Championship every year, bringing thousands of motorsports fans to the Hidden Valley Raceway. Also in Hidden Valley, adjacent to the road-racing circuit, is Darwin's dirt track racing venue, Northline Speedway. The speedway has hosted a number of Australian Championships over the years for different categories including Sprintcars, Speedcars, and Super Sedans.

The Darwin Cup culminating on the first Monday of August is a popular horse race event for Darwin and draws large crowds every year to Fannie Bay Racecourse. While it is not as popular as the Melbourne Cup, it does draw a crowd and, in 2003, Sky Racing began televising most of the races. The Darwin Cup day is a public holiday for the Northern Territory (Picnic Day public holiday).

There is one greyhound racing track in Darwin at Winnellie Park on Hook Road. It is the only track in the Northern Territory.

In 2022, the Darwin Salties basketball club will debut in the Queensland-based NBL1 North competition, making the NBL1 the first Australian sport league to have clubs based in and playing out of every state and territory in Australia.

As well as Christian stations Faith 88.4 FM, Rhema 97.7 FM and Vision Radio 1323 AM.

Transport
The Territory's public transport services are managed by the Department of Lands and Planning, Public Transport Division. Darwin has a bus network serviced by a range of contracted bus operators, which provides transport to the main suburbs of Darwin.

Darwin has no commuter rail system, but long-distance passenger rail services do operate out of the city. The Alice Springs-Darwin railway line was completed in 2003, linking Darwin to Adelaide. The first service ran in 2004. The Ghan passenger train service from Adelaide via Alice Springs and Katherine runs once per week in each direction, with some exceptions.

Historically, the North Australia Railway carried passengers and freight from Darwin into the interior, reaching Pine Creek in 1889, Katherine in 1917, and Birdum in 1929. It was closed due to declining traffic in 1976.

Darwin International Airport, in the suburb of Eaton, is Darwin's only airport, which shares its runways with the Royal Australian Air Force's RAAF Base Darwin.

Darwin can be reached via the Stuart Highway, which runs the length of the Northern Territory from Darwin through Katherine, Tennant Creek, Alice Springs, and on to Adelaide. Other major roads in Darwin include Tiger Brennan Drive, Amy Johnson Avenue, Dick Ward Drive, Bagot Road, Trower Road, and McMillans Road. Bus service in the greater Darwin area is provided by Darwinbus.

Port
Ferries leave from Port Darwin to island locations, mainly for tourists. A ferry service to the Tiwi Islands, the Arafura Pearl, operates from Cullen Bay.

Darwin has a deepwater port, East Arm Wharf, which opened in 2000. It has 754 m of wharfline and is capable of handling Panamax-sized ships of a maximum length of 274 m and a DWT of up to 80000 tonne.

Health
The Government of the Northern Territory Department of Health and Families oversees one public hospital in the Darwin metropolitan region. The Royal Darwin Hospital, in Tiwi, is the city's major teaching and referral hospital, and the largest in the Northern Territory.

There is one major private hospital, Darwin Private Hospital, in Tiwi, adjacent to the Royal Darwin Hospital. Darwin Private Hospital is operated and owned by Healthscope Ltd, a private hospital corporation.

A new hospital called Palmerston Regional Hospital was opened in August 2018 to help ease the pressure of patient numbers at the Royal Darwin Hospital.

Utilities
Water storage, supply and power for Darwin is managed by Power and Water Corporation, which is owned by the Government of the Northern Territory. The corporation is also responsible for management of sewage and the major water catchments in the region. Water is mainly stored in the largest dam, The Darwin River Dam, which holds up to 90% of Darwin's water supply. For many years, Darwin's principal water supply came from Manton Dam.

Darwin and its suburbs, Palmerston and Katherine, are powered by the Channel Island Power Station, the Northern Territory's largest power plant, and the Weddell Power Station.

Telecommunications
Darwin once had Australia's only international connection to the outside world in the form of an overseas telegraph cable, connecting Darwin to Java. The southern section of the cable connected Darwin with Adelaide and was known as the overland telegraph line. In 2022, the Northern Territory Government announced that an international undersea cable system would land into Darwin, directly connecting it to Indonesia, Singapore, the United States and Timor Leste. The new cable system, representing an investment of $700 million, is expected to create a new digital economy as it is coupled with recent announcements on Data Centre Investment into Darwin. The plans for Darwin for Data Centres and International cables are outlined in the Northern Territory's Digital Strategy the Terabit Territory.

Dictator

A dictator is a political leader who possesses absolute power. A dictatorship is a state ruled by one dictator or by a polity. The word originated as the title of a Roman dictator elected by the Roman Senate to rule the republic in times of emergency. Like the term tyrant, and to a lesser degree autocrat, dictator came to be used almost exclusively as a non-titular term for oppressive rule. In modern usage the term dictator is generally used to describe a leader who holds or abuses an extraordinary amount of personal power.

Dictatorships are often characterised by some of the following: suspension of elections and civil liberties; proclamation of a state of emergency; rule by decree; repression of political opponents; not abiding by the procedures of the rule of law; and the existence of a cult of personality centered on the leader. Dictatorships are often one-party or dominant-party states. A wide variety of leaders coming to power in different kinds of regimes, such as one-party or dominant-party states and civilian governments under a personal rule, have been described as dictators.

Etymology
The word dictator comes from the Latin word dictātor, agent noun from dictare (say repeatedly, assert, order). A dictator was a Roman magistrate given sole power for a limited duration. Originally an emergency legal appointment in the Roman Republic and the Etruscan culture, the term dictator did not have the negative meaning it has now. It started to get its modern negative meaning with Cornelius Sulla's ascension to the dictatorship following Sulla's civil war, making himself the first Dictator in Rome in more than a century (during which the office was ostensibly abolished) as well as de facto eliminating the time limit and need of senatorial acclamation.

He avoided a major constitutional crisis by resigning the office after about one year, dying a few years later. Julius Caesar followed Sulla's example in 49 BC and in February 44 BC was proclaimed Dictator perpetuo, "Dictator in perpetuity", officially doing away with any limitations on his power, which he kept until his assassination the following month. Following Caesar's assassination, his heir Augustus was offered the title of dictator, but he declined it. Later successors also declined the title of dictator, and usage of the title soon diminished among Roman rulers.

Modern era

As late as the second half of the 19th century, the term dictator had occasional positive implications. For example, during the Hungarian Revolution of 1848, the national leader Lajos Kossuth was often referred to as dictator, without any negative connotations, by his supporters and detractors alike, although his official title was that of regent-president. When creating a provisional executive in Sicily during the Expedition of the Thousand in 1860, Giuseppe Garibaldi officially assumed the title of "dictator" (see Dictatorship of Garibaldi). Shortly afterwards, during the 1863 January uprising in Poland, "Dictator" was also the official title of four leaders, the first being Ludwik Mierosławski.

Past that time, however, the term dictator assumed an invariably negative connotation. In popular usage, a dictatorship is often associated with brutality and oppression. As a result, it is often also used as a term of abuse against political opponents. The term has also come to be associated with megalomania. Many dictators create a cult of personality around themselves and they have also come to grant themselves increasingly grandiloquent titles and honours. For instance, Idi Amin Dada, who had been a British army lieutenant prior to Uganda's independence from Britain in October 1962, subsequently styled himself "His Excellency, President for Life, Field Marshal Al Hadji Doctor Idi Amin Dada, VC, DSO, MC, Conqueror of the British Empire in Africa in General and Uganda in Particular". In the movie The Great Dictator (1940), Charlie Chaplin satirized not only Adolf Hitler but the institution of dictatorship itself.

Benevolent dictatorship
A benevolent dictatorship refers to a government in which an authoritarian leader exercises absolute political power over the state but is perceived to do so with regard for the benefit of the population as a whole, standing in contrast to the decidedly malevolent stereotype of a dictator. A benevolent dictator may allow for some civil liberties or democratic decision-making to exist, such as through public referendums or elected representatives with limited power, and often makes preparations for a transition to genuine democracy during or after their term. The label has been applied to leaders such as Mustafa Kemal Atatürk of Turkey	(1923–38), Josip Broz Tito of SFR Yugoslavia (1953–80), and Lee Kuan Yew of Singapore (1959–90).

Military roles
The association between a dictator and the military is a common one. Many dictators take great pains to emphasize their connections with the military and they often wear military uniforms. In some cases, this is perfectly legitimate; for instance, Francisco Franco was a general in the Spanish Army before he became Chief of State of Spain, and Manuel Noriega was officially commander of the Panamanian Defense Forces. In other cases, the association is mere pretense.

Crowd manipulation
Some dictators have been masters of crowd manipulation, such as Benito Mussolini and Adolf Hitler. Others were more prosaic speakers, such as Joseph Stalin and Francisco Franco. Typically, the dictator's people seize control of all media, censor or destroy the opposition, and give strong doses of propaganda daily, often built around a cult of personality.

Mussolini and Hitler used similar, modest titles referring to them as "the Leader". Mussolini used "Il Duce" and Hitler was generally referred to as "der Führer", both meaning 'Leader' in Italian and German respectively. Franco used a similar title "El Caudillo" ("the Head", 'the chieftain') and for Stalin his adopted name, meaning "Man of Steel", became synonyms with his role as the absolute leader. For Mussolini, Hitler, and Franco, the use of modest, non-traditional titles displayed their absolute power even stronger as they did not need any, not even a historic legitimacy either. However, in the case of Franco, the title "Caudillo" did have a longer history for political-military figures in both Latin America and Spain. Franco also used the phrase "By the Grace of God" on coinage or other material displaying him as Caudillo, whereas Hitler and Mussolini rarely used such monarchical-associated language or imagery.

Criticism
The usage of the term dictator in western media has been criticized by the left-leaning organization Fairness & Accuracy in Reporting as "Code for Government We Don't Like". According to them, leaders that would generally be considered authoritarian but are allied with the US such as Paul Biya or Nursultan Nazarbayev are rarely referred to as "dictators", while leaders of countries opposed to U.S. policy such as Nicolás Maduro or Bashar al-Assad have the term applied to them much more liberally.

Modern usage in formal titles

Because of its negative and pejorative connotations, modern authoritarian leaders very rarely (if ever) use the term dictator in their formal titles, instead they most often simply have title of president. In the 19th century, however, its official usage was more common:

 * The Dictatorial Government of Sicily (27 May – 4 November 1860) was a provisional executive government appointed by Giuseppe Garibaldi to rule Sicily. The government ended when Sicily's annexation into the Kingdom of Italy was ratified by plebiscite.
 * Marian Langiewicz of Poland proclaimed himself Dictator and attempted (unsuccessfully) to form a Polish government in March 1863.
 * Romuald Traugutt was Dictator of Poland from 17 October 1863 to 10 April 1864.
 * The Dictatorial Government of the Philippines (1898–1898) was an insurgent government in the Philippines which was headed by Emilio Aguinaldo, who formally held the title of Dictator. The dictatorial government was superseded by the revolutionary government with Aguinaldo as president.

Human rights abuses, war crimes and genocides

Over time, dictators have been known to use tactics that violate human rights. For example, under the Soviet dictator Joseph Stalin, government policy was enforced by secret police and the Gulag system of prison labour camps. Most Gulag inmates were not political prisoners, although significant numbers of political prisoners could be found in the camps at any one time. Data collected from Soviet archives gives the death toll from Gulags as 1,053,829. The International Criminal Court issued an arrest warrant for Sudan's military dictator Omar al-Bashir over alleged war crimes in Darfur.

Similar crimes were committed during Chairman Mao Zedong's rule over the People's Republic of China during China's Cultural Revolution, where Mao set out to purge dissidents, primarily through the use of youth groups strongly committed to his cult of personality, and during Augusto Pinochet's junta in Chile. Some dictators have been associated with genocide on certain races or groups; the most notable and wide-reaching example is the Holocaust, Adolf Hitler's genocide of eleven million people, of whom six million were Jews. Later on in Democratic Kampuchea, General Secretary Pol Pot and his policies killed an estimated 1.7 million people (out of a population of 7 million) during his four-year dictatorship. As a result, Pol Pot is sometimes described as "the Hitler of Cambodia" and "a genocidal tyrant".
