Chanakya

Chanakya (ISO: ', ; 375–283 BCE) was an ancient Indian polymath who was active as a teacher, author, strategist, philosopher, economist, jurist, and politician.He was the first Prime Minister of the Maurya Empire.He is traditionally identified as Kauṭilya or Viṣṇugupta', who authored the ancient Indian political treatise, the Arthashastra'', a text dated to roughly between the fourth century BCE and the third century CE. As such, he is considered the pioneer of the field of political science and economics in India, and his work is thought of as an important precursor to classical economics. His works were lost near the end of the Gupta Empire in the sixth century CE and not rediscovered until the early 20th century. Around 321 BCE, Chanakya assisted the first Mauryan emperor Chandragupta in his rise to power and is widely credited for having played an important role in the establishment of the Maurya Empire. Chanakya served as the chief advisor and Prime Minister of the both emperors Chandragupta Maurya and his son Bindusara.

Sources of information
There is little documented historical information about Chanakya: most of what is known about him comes from semi-legendary accounts. Thomas Trautmann identifies four distinct accounts of the ancient Chanakya-Chandragupta katha (legend):

In all the four versions, Chanakya feels insulted by the Nanda king, and vows to destroy him. After dethroning the Nanda, he installs Chandragupta as the new king.

Buddhist version

 * The legend of Chanakya and Chandragupta is detailed in the Pali-language Buddhist chronicles of Sri Lanka. It is not mentioned in Dipavamsa, the oldest of these chronicles. The earliest Buddhist source to mention the legend is Mahavamsa, which is generally dated between fifth and sixth centuries CE. Vamsatthappakasini (also known as Mahvamsa Tika), a commentary on Mahavamsa, provides some more details about the legend. Its author is unknown, and it is dated variously from sixth century CE to 13th century CE. Some other texts provide additional details about the legend; for example, the Maha-Bodhi-Vamsa and the Atthakatha give the names of the nine Nanda kings said to have preceded Chandragupta.

Jain version

 * The Chandragupta-Chanakya legend is mentioned in several commentaries of the Shvetambara canon. The most well-known version of the Jain legend is contained in the Sthaviravali-Charita or Parishishta-Parvan, written by the 12th-century writer Hemachandra. Hemachandra's account is based on the Prakrit kathanaka literature (legends and anecdotes) composed between the late first century CE and mid-8th century CE. These legends are contained in the commentaries (churnis and tikas) on canonical texts such as Uttaradhyayana and Avashyaka Niryukti.
 * Thomas Trautmann believes that the Jain version is older and more consistent than the Buddhist version of the legend.

Kashmiri version

 * Brihatkatha-Manjari by Kshemendra and Kathasaritsagara by Somadeva are two 11th-century Kashmiri Sanskrit collections of legends. Both are based on a now-lost Prakrit-language Brihatkatha-Sarit-Sagara, which was based on the now-lost Paishachi-language Brihatkatha by Gunadhya. The Chanakya-Chandragupta legend in these collections features another character, named Shakatala (IAST: Śakaṭāla).

Mudrarakshasa version

 * Mudrarakshasa ("The signet ring of Rakshasa") is a Sanskrit play by Vishakhadatta. Its date is uncertain, but it mentions the Huna, who invaded northern India during the Gupta period. Therefore, it could not have been composed before the Gupta era. It is dated variously from the late fourth century to the eighth century. The Mudrarakshasa legend contains narratives not found in other versions of the Chanakya-Chandragupta legend. Because of this difference, Trautmann suggests that most of it is fictional or legendary, without any historical basis.

Identification with Kauṭilya or Vishnugupta
The ancient Arthashastra has been traditionally attributed to Chanakya by a number of scholars. The Arthashastra identifies its author as Kauṭilya, a gotra or clan name, except for one verse that refers to him by the personal name of Vishnugupta. Kauṭilya is presumably the name of the author's gotra (clan). One of the earliest Sanskrit literatures to identify Chanakya with Vishnugupta explicitly was the Panchatantra.

K. C. Ojha proposes that the traditional identification of Vishnugupta with Kauṭilya was caused by a confusion of the text's editor and its originator. He suggests that Vishnugupta was a redactor of the original work of Kauṭilya. Thomas Burrow suggests that Chanakya and Kauṭilya may have been two different people.

Jain legend
According to the Jain account, Chanakya was born to two lay Jains (shravaka) named Chanin and Chaneshvari. His birthplace was the Chanaka village in Golla vishaya (district). The identity of "Golla" is not certain, but Hemachandra states that Chanakya was a Dramila, implying that he was a native of South India.

Chanakya was born with a full set of teeth. According to the monks, this was a sign that he would become a king in the future. Chanin did not want his son to become haughty, so he broke Chanakya's teeth. The monks prophesied that the baby would go on to become a power behind the throne. Chanakya grew up to be a learned shravaka, and married a Brahmin woman. Her relatives mocked her for being married to a poor man. This motivated Chanakya to visit Pataliputra, and seek donations from the Emperor Nanda, who was famous for his generosity towards Brahmins. While waiting for the emperor at the imperial court, Chanakya sat on the emperor's throne. A dasi (slave woman) courteously offered Chanakya the next seat, but Chanakya kept his kamandal (water pot) on it, while remaining seated on the throne. The servant offered him a choice of four more seats, but each time, he kept his various items on the seats, refusing to budge from the throne. Finally, the annoyed servant kicked him off the throne. Enraged, Chanakya vowed to uproot Nanda and his entire establishment, like "a great wind uproots a tree".

Chanakya knew that he was prophesied to become a power behind the throne. So, he started searching for a person worthy of being a king. While wandering, he did a favour for the pregnant daughter of a village chief, on the condition that her child would belong to him. Chandragupta was born to this lady. When Chandragupta grew up, Chanakya came to his village and saw him playing "king" among a group of boys. To test him, Chanakya asked him for a donation. The boy told Chanakya to take the cows nearby, declaring that nobody would disobey his order. This display of power convinced Chanakya that Chandragupta was the one worthy of being a king.

Chanakya took Chandragupta to conquer Pataliputra, the capital of Nanda. He assembled an army using the wealth he had acquired through alchemy (dhatuvada-visaradan). The army suffered a severe defeat, forcing Chanakya and Chandragupta to flee the battlefield. They reached a lake while being pursued by an enemy officer. Chanakya asked Chandragupta to jump into the lake, and disguised himself as a meditating ascetic. When the enemy soldier reached the lake, he asked the 'ascetic' if he had seen Chandragupta. Chanakya pointed at the lake. As the soldier removed his armour to jump into the lake, Chanakya took his sword and killed him. When Chandragupta came out of the water, Chanakya asked him, "What went through your mind, when I disclosed your location to the enemy?" Chandragupta replied that he trusted his master to make the best decision. This convinced Chanakya that Chandragupta would remain under his influence even after becoming the king. On another occasion, Chanakya similarly escaped the enemy by chasing away a washerman, and disguising himself as one. Once, he cut open the belly of a Brahmin who had just eaten food, and took out the food to feed a hungry Chandragupta.

One day, Chanakya and Chandragupta overheard a woman scolding her son. The child had burnt his finger by putting it in the middle of a bowl of hot gruel. The woman told her son that by not starting from the cooler edges, he was being foolish like Chanakya, who attacked the capital before conquering the bordering regions. Chanakya realized his mistake, and made a new plan to defeat Nanda. He formed an alliance with Parvataka, the king of a mountain kingdom called Himavatkuta, offering him half of Nanda's empire.

After securing Parvataka's help, Chanakya and Chandragupta started besieging the cities other than Pataliputra. One particular city offered a strong resistance. Chanakya entered this city disguised as a Shaivite mendicant, and declared that the siege would end if the idols of the seven mothers were removed from the town's temple. As soon as the superstitious defenders removed the idols from the temple, Chanakya ordered his army to end the siege. When the defenders started celebrating their victory, Chanakya's army launched a surprise attack and captured the town.

Gradually, Chanakya and Chandragupta subdued all the regions outside the capital. Finally, they captured Pataliputra and Chandragupta became the emperor. They allowed the Emperor Nanda to go into exile, with all the goods he could take on a cart. As Nanda and his family were leaving the city on a cart, his daughter saw Chandragupta, and fell in love with the new emperor. She chose him as her husband by svayamvara tradition. As she was getting off the cart, 9 spokes of the cart's wheel broke. Interpreting this as an omen, Chanakya declared that Chandragupta's dynasty would last for 9 generations.

Meanwhile, Parvataka fell in love with one of Nanda's visha kanyas (poison girl, assassin). Chanakya approved the marriage, and Parvataka collapsed when he touched the girl during the wedding. Chanakya asked Chandragupta not to call a physician. Thus, Parvataka died and Chandragupta became the sole ruler of Nanda's territories.

Chanakya then started consolidating the power by eliminating Nanda's loyalists, who had been harassing people in various parts of the empire. Chanakya learned about a weaver who would burn any part of his house infested with cockroaches. Chanakya assigned the responsibility of crushing the rebels to this weaver. Soon, the empire was free of insurgents. Chanakya also burned a village that had refused him food in the past. He filled the imperial treasury by inviting rich merchants to his home, getting them drunk and gambling with a loaded dice.

Once, the empire suffered a 12-year long famine. Two young Jain monks started eating from the emperor's plate, after making themselves invisible with a magic ointment. Chanakya sensed their presence by covering the palace floor with a powder, and tracing their footprints. At the next meal, he caught them by filling the dining room with thick smoke, which caused the monks' eyes to water, washing off the ointment. Chanakya complained about the young monks' behavior to the head monk Acharya Susthita. The Acharya blamed people for not being charitable towards monks, so Chanakya started giving generous alms to the monks.

Meanwhile, Chandragupta had been patronizing the non-Jain monks. Chanakya decided to prove to him that these men were not worthy of his patronage. He covered the floor of the palace area near the women's rooms with powder and left the non-Jain monks there. Their footprints showed that they had sneaked up to the windows of the women's rooms to peep inside. The Jain monks, who were assessed using the same method, stayed away from the women's rooms. After seeing this, Chandragupta appointed the Jain monks as his spiritual counsellors.

Chanakya used to mix small doses of poison in Chandragupta's food to make him immune to poisoning attempts. The emperor, unaware of this, once shared his food with Empress Durdhara. Chanakya entered the room at the instant she died. He cut open the dead empress's belly and took out the baby. The baby, who had been touched by a drop ("bindu") of the poison, was named Bindusara.

After Chandragupta abdicated the throne to become a Jain monk, Chanakya appointed Bindusara as the new emperor. Chanakya asked Bindusara to appoint a man named Subandhu as one of his ministers. However, Subandhu wanted to become a higher minister and grew jealous of Chanakya. So, he told Bindusara that Chanakya was responsible for the death of his mother. Bindusara confirmed the allegations with the nurses, who told him that Chanakya had cut open the belly of his mother. Bindusara became enraged, and started hating Chanakya. As a result, Chanakya, who had grown very old by this time, retired and decided to starve himself to death. Meanwhile, Bindusara learned the detailed circumstances of his birth, and implored Chanakya to resume his ministerial duties. After failing to pacify Chanakya, the emperor ordered Subandhu to convince Chanakya to give up his suicide plan. Subandhu, while pretending to appease Chanakya, burned him to death. Subandhu then took possession of Chanakya's home. Chanakya had anticipated this, and before retiring, he had set up a cursed trap for Subandhu. He had left behind a chest with a hundred locks. Subandhu broke the locks, hoping to find precious jewels. He found a sweet-smelling perfume and immediately inhaled it. But then his eyes fell on a birch bark note with a curse written on it. The note declared that anybody who smelled this perfume will have to either become a monk or face death. Subandhu tested the perfume on another man, and then fed him luxurious food (something that the monks abstain from). The man died, and then Subandhu was forced to become a monk to avoid death.

According to another Jain text – the Rajavali-Katha – Chanakya accompanied Chandragupta to forest for retirement, once Bindusara became the emperor.

Buddhist legend
According to the Buddhist legend, the Nanda emperors who preceded Chandragupta were robbers-turned-rulers. Chanakya (IAST: Cāṇakka in Mahavamsa) was a Brahmin from Takkāsila (Takshashila). He was well-versed in three Vedas and politics. He was born with canine teeth, which were believed to be a mark of royalty. His mother feared that he would neglect her after becoming an emperor. To pacify her, Chanakya broke his teeth.

Chanakya had an ugly appearance, accentuated by his broken teeth and crooked feet. One day, the Emperor Dhana Nanda organized an alms-giving ceremony for Brahmins. Chanakya went to Pupphapura (Pushpapura) to attend this ceremony. Disgusted by his appearance, the emperor ordered him to be thrown out of the assembly. Chanakya broke his sacred thread in anger, and cursed the emperor. The emperor ordered his arrest, but Chanakya escaped in the disguise of an Ājīvika. He befriended Dhananada's son Pabbata, and instigated him to seize the throne. With help of a signet ring given by the prince, Chanakya fled the palace through a secret door.

Chanakya escaped to the Vinjha forest. There, he made 800 million gold coins (kahapanas), using a secret technique that allowed him to turn 1 coin into 8 coins. After hiding this money, he started searching for a person worthy of replacing Dhana Nanda. One day, he saw a group of children playing: the young Chandragupta (called Chandagutta in Mahavamsa) played the role of a emperor, while other boys pretended to be vassals, ministers, or robbers. The "robbers" were brought before Chandragupta, who ordered their limbs to be cut off, but then miraculously re-attached them. Chandragupta had been born in a royal family, but was brought up by a hunter after his father was killed by an usurper, and the devatas caused his mother to abandon him. Astonished by the boy's miraculous powers, Chanakya paid 1000 gold coins to his foster-father, and took Chandragupta away, promising to teach him a trade.

Chanakya had two potential successors to Dhana Nanda: Pabbata and Chandragupta. He gave each of them an amulet to be worn around the neck with a woolen thread. One day, he decided to test them. While Chandragupta was asleep, he asked Pabbata to remove Chandragupta's woolen thread without breaking it and without waking up Chandragupta. Pabbata failed to accomplish this task. Some time later, when Pabbata was sleeping, Chanakya challenged Chandragupta to complete the same task. Chandragupta retrieved the woolen thread by cutting off Pabbata's head. For the next seven years, Chanakya trained Chandragupta for imperial duties. When Chandragupta became an adult, Chanakya dug up his hidden treasure of gold coins, and assembled an army.

The army of Chanadragupta and Chanakya invaded Dhana Nanda's empire, but disbanded after facing a severe defeat. While wandering in disguise, the two men once listened to the conversation between a woman and her son. The child had eaten the middle of a cake, and thrown away the edges. The woman scolded him, saying that he was eating food like Chandragupta, who attacked the central part of the empire instead of conquering the border villages first. Chanakya and Chandragupta realized their mistake. They assembled a new army, and started conquering the border villages. Gradually, they advanced to the empire's capital Pataliputra (Pāṭaliputta in Mahavamsa), where they killed the Emperor Dhana Nanda. Chanakya ordered a fisherman to find the place where Dhana Nanda had hidden his treasure. As soon as the fishermen informed Chanakya about its location, Chanakya had him killed. Chanakya anointed Chandragupta as the new emperor, and tasked a man named Paṇiyatappa with eliminating rebels and robbers from the empire.

Chanakya started mixing small doses of poison in the new emperor's food to make him immune to poisoning attempts by the enemies. Chandragupta, who was not aware of this, once shared the food with his pregnant empress Durdhara, who was seven days away from delivery. Chanakya arrived just as the empress ate the poisoned morsel. Realizing that she was going to die, Chanakya decided to save the unborn child. He cut off the empress's head and cut open her belly with a sword to take out the foetus. Over the next seven days, he placed the foetus in the belly of a goat freshly killed each day. After seven days, Chandragupta's son was "born". He was named Bindusara because his body was spotted with drops (bindu) of goat's blood.

The earliest Buddhist legends do not mention Chanakya in their description of the Mauryan dynasty after this point. Dhammapala's commentary on Theragatha, however, mentions a legend about Chanakya and a Brahmin named Subandhu. According to this account, Chanakya was afraid that the wise Subandhu would surpass him at Chandragupta's court. So, he got Chandragupta to imprison Subandhu, whose son Tekicchakani escaped and became a Buddhist monk. The 16th-century Tibetan Buddhist author Taranatha mentions Chanakya as one of Bindusara's "great lords". According to him, Chanakya destroyed the nobles and kings of 16 towns and made Bindusara the master of all the territory between the eastern and the western seas (Arabian Sea and the Bay of Bengal).

Kashmiri legend
The Kashmiri version of the legend goes like this: Vararuchi (identified with Katyayana), Indradatta and Vyadi were three disciples of the sage Varsha. Once, on behalf of their guru Varsha, they travelled to Ayodhya to seek a gurudakshina (guru's fee) from Emperor Nanda. As they arrived to meet Nanda, the emperor died. Using his yogic powers, Indradatta entered Nanda's body and granted Vararuchi's request for 10 million gold dinars (gold coins). The imperial minister Shakatala realized what was happening, and had Indradatta's body burnt. But before he could take any action against the fake emperor (Indradatta in Nanda's body, also called Yogananda), the emperor had him arrested. Shakatala and his 100 sons were imprisoned and were given food sufficient only for one person. Shakatala's 100 sons starved to death, so that their father could live to take revenge.

Meanwhile, the fake emperor appointed Vararuchi as his minister. As the emperor's character kept deteriorating, a disgusted Vararuchi retired to a forest as an ascetic. Shakatala was then restored as the minister, but kept planning his revenge. One day, Shakatala came across Chanakya, a Brahmin who was uprooting all the grass in his path, because one blade of the grass had pricked his foot. Shakatala realized that he could use a man so vengeful to destroy the fake emperor. He invited Chanakya to the emperor's assembly, promising him 100,000 gold coins for presiding over a ritual ceremony.

Shakatala hosted Chanakya in his own house and treated him with great respect. But the day Chanakya arrived at the imperial court, Shakatala got another Brahmin named Subandhu to preside over the ceremony. Chanakya felt insulted, but Shakatala blamed the emperor for this dishonour. Chanakya then untied his topknot (sikha), and vowed not to re-tie it until the emperor was destroyed. The emperor ordered his arrest, but he escaped to Shakatala's house. There, using materials supplied by Shakatala, he performed a magic ritual which made the emperor sick. The king died of a fever after 7 days.

Shakatala then executed Hiranyagupta, the son of the fake emperor. He anointed Chandragupta, the son of the real emperor Nanda, as the new emperor (in Kshemendra's version, it is Chanakya who installs Chandragupta as the new emperor). Shakatala also appointed Chanakya as the imperial priest (rajpurohita). Having achieved his revenge, he then retired to the forest as an ascetic.

Mudrarakshasa legend
According to the Mudrarakshasa version, the Emperor Nanda once removed Chanakya from the "first seat of the empire" (this possibly refers to Chanakya's expulsion from the emperor's assembly). For this reason, Chanakya vowed not to tie his top knot (shikha) until the complete destruction of Nanda. Chanakya made a plan to dethrone Nanda, and replace him with Chandragupta, his son by a lesser empress. Chanakya engineered Chandragupta's alliance with another powerful king Parvateshvara (or Parvata), and the two rulers agreed to divide Nanda's territory after subjugating him. Their allied army included Bahlika, Kirata, Parasika, Kamboja, Shaka, and Yavana soldiers. The army invaded Pataliputra (Kusumapura) and defeated the Nandas. Parvata is identified with King Porus by some scholars.

Nanda's prime minister Rakshasa escaped Pataliputra, and continued resisting the invaders. He sent a vishakanya (poison girl) to assassinate Chandragupta. Chanakya had this girl assassinate Parvata instead, with the blame going to Rakshasa. However, Parvata's son Malayaketu learned the truth about his father's death and defected to Rakshasa's camp. Chanakya's spy Bhagurayana accompanied Malayaketu, pretending to be his friend.

Rakshasa continued to plot Chandragupta's death, but all his plans were foiled by Chanakya. For example, once Rakshasa arranged for assassins to be transported to Chandragupta's bedroom via a tunnel. Chanakya became aware of them by noticing a trail of ants carrying the leftovers of their food. He then arranged for the assassins to be burned to death.

Meanwhile, Parvata's brother Vairodhaka became the ruler of his emperor. Chanakya convinced him that Rakshasa was responsible for killing his brother, and agreed to share half of Nanda's emperor with him. Secretly, however, Chanakya hatched a plan to get Vairodhaka killed. He knew that the chief architect of Pataliputra was a Rakshasa loyalist. He asked this architect to build a triumphal arch for Chandragupta's procession to the imperial palace. He arranged the procession to be held at midnight citing astrological reasons, but actually to ensure poor visibility. He then invited Vairodhaka to lead the procession on Chandragupta's elephant, and accompanied by Chandragupta's bodyguards. As expected, Rakshasa's loyalists arranged for the arch to fall on who they thought was Chandragupta. Vairodhaka was killed, and once again, the assassination was blamed on Rakshasa.

Malayaketu and Rakshasa then formed an alliance with five kings: Chiravarman of Kauluta (Kulu), Meghaksha of Parasika, Narasimha of Malaya, Pushkaraksha of Kashmira, and Sindhusena of Saindhava. This allied army also included soldiers from Chedi, Gandhara, Hunas, Khasa, Magadha, Shaka, and Yavana territories.

In Pataliputra, Chanakya's agent informed him that three Rakshasa loyalists remained in the capital: the Jain monk Jiva-siddhi, the scribe Shakata-dasa and the jewellers' guild chief Chandana-dasa. Of these, Jiva-siddhi was actually a spy of Chanakya, unknown to his other spies. Chandana-dasa sheltered Rakshasa's wife, who once unknowingly dropped her husband's signet-ring (mudra). Chanakya's agent got hold of this signet-ring, and brought it to Chanakya. Using this signet ring, Chanakya sent a letter to Malayaketu warning him that his allies were treacherous. Chanakya also asked some of Chandragupta's princes to fake defection to Malayaketu's camp. In addition, Chanakya ordered Shakata-dasa's murder, but had him 'rescued' by Siddharthaka, a spy pretending to be an agent of Chandana-dasa. Chanakya's spy then took Shakata-dasa to Rakshasa.

When Shakata-dasa and his 'rescuer' Siddharthaka reached Rakshasa, Siddharthaka presented him the signet-ring, claiming to have found it at Chandana-dasa's home. As a reward, Rakshasa gave him some jewels that Malayaketu had gifted him. Sometime after this, another of Chanakya's agents, disguised as a jeweller, sold Parvata's jewels to Rakshasa.

Sometime later, Rakshasa sent his spies disguised as musicians to Chandragupta's court. But Chanakya knew all about Rakshasa's plans thanks to his spies. In front of Rakshasa's spies, Chanakya and Chandragupta feigned an angry argument. Chandragupta pretended to dismiss Chanakya, and declared that Rakshasa would make a better minister. Meanwhile, Malayaketu had a conversation with Chanakya's spy Bhagurayana while approaching Rakshasa's house. Bhagurayana made Malayaketu distrustful of Rakshasa, by saying that Rakshasa hated only Chanakya, and would be willing to serve Nanda's son Chandragupta. Shortly after this, a messenger came to Rakshasa's house and informed him that Chandragupta had dismissed Chanakya while praising him. This convinced Malayaketu that Rakashasa could not be trusted.

Malayaketu then decided to invade Pataliputra without Rakshasa by his side. He consulted the Jain monk Jiva-siddhi to decide an auspicious time for beginning the march. Jiva-siddhi, a spy of Chanakya, told him that he could start immediately. Jiva-siddhi also convinced him that Rakshasa was responsible for his father's death, but Bhagurayana persuaded him not to harm Rakshasa. Shortly after, Chanakya's spy Siddharthaka pretended to get caught with a fake letter addressed to Chandragupta by Rakshasa. Wearing the jewels given by Rakshasa, he pretended to be an agent of Rakshasa. The letter, sealed with Rakshasa's signet-ring, informed Chandragupta that Rakshasa only wished to replace Chanakya as the prime minister. It also stated that five of Malayaketu's allies were willing to defect to Chandragupta in return for land and wealth. An angry Malayaketu summoned Rakshasa, who arrived wearing Parvata's jewels that Chanakya's agent had sold him. When Malayaketu saw Rakshasa wearing his father's jewels, he was convinced that there was indeed a treacherous plan against him. He executed his five allies in a brutal manner.

The rest of Malayaketu's allies deserted him, disgusted at his treatment of the five slayed allies. Rakshasa managed to escape, tracked by Chanakya's spies. One of Chanakya's spies, disguised as a friend of Chandana-dasa, got in touch with him. He told Rakshasa that Chandana-dasa was about to be executed for refusing to divulge the location of Rakshasa's family. On hearing this, Rakshasa rushed to Pataliputra to surrender and save the life of his loyal friend Chandana-dasa. When he reached Pataliputra, Chanakya, pleased with his loyalty to Chandana-dasa, offered him clemency. Rakshasa pledged allegiance to Chandragupta and agreed to be his prime minister, in return for release of Chandana-dasa and a pardon for Malayaketu. Chanakya then bound his top knot, having achieved his objective, and retired.

Literary works
Two books are attributed to Chanakya: Arthashastra, and Chanakya Niti, also known as Chanakya Neeti-shastra. The Arthashastra was discovered in 1905 by librarian Rudrapatna Shamasastry in an uncatalogued group of ancient palm-leaf manuscripts donated by an unknown pandit to the Oriental Research Institute Mysore.
 * The Arthashastra, which discusses monetary and fiscal policies, welfare, international relations, and war strategies in detail. The text also outlines the duties of a ruler. Some scholars believe that Arthashastra is actually a compilation of a number of earlier texts written by various authors, and Chanakya might have been one of these authors (see above).
 * Chanakya Niti, which is a collection of aphorisms, said to be selected by Chanakya from the various shastras.

Legacy
Chanakya is regarded as a great thinker and diplomat in India. Many Indian nationalists regard him as one of the earliest people who envisioned a united India spanning the entire subcontinent. India's former National Security Advisor Shiv Shankar Menon praised Chanakya's Arthashastra for its precise and timeless descriptions of power. Furthermore, he recommended reading of the book for broadening the vision on strategic issues.

The diplomatic enclave in New Delhi is named Chanakyapuri in honour of Chanakya. Institutes named after him include Training Ship Chanakya, Chanakya National Law University and Chanakya Institute of Public Leadership. Chanakya circle in Mysore has been named after him.

Chanakyan vocabulary
Chanakya uses different terms to describe war other than dharma-yuddha (just war), such as kutayudhha (unjust war).

Plays
Several modern adaptations of the legend of Chanakya narrate his story in a semi-fictional form, extending these legends. In Chandragupta (1911), a play by Dwijendralal Ray, the Nanda king exiles his half-brother Chandragupta, who joins the army of Alexander the Great. Later, with help from Chanakya and Katyayan (the former Prime Minister of Magadha), Chandragupta defeats Nanda, who is put to death by Chanakya.

Batman Begins

Batman Begins is a 2005 superhero film directed by Christopher Nolan and written by Nolan and David S. Goyer. Based on the DC Comics character Batman, it stars Christian Bale as Bruce Wayne / Batman, with Michael Caine, Liam Neeson, Katie Holmes, Gary Oldman, Cillian Murphy, Tom Wilkinson, Rutger Hauer, Ken Watanabe, and Morgan Freeman in supporting roles. The film reboots the Batman film series, telling the origin story of Bruce Wayne from the death of his parents to his journey to become Batman and his fight to stop Ra's al Ghul and the Scarecrow from plunging Gotham City into chaos.

After Batman & Robin was panned by critics and underperformed at the box office, Warner Bros. Pictures cancelled future Batman films, including Joel Schumacher's planned Batman Unchained. Between 1998 and 2003, several filmmakers collaborated with Warner Bros. in attempting to reboot the franchise. After the studio rejected a Batman origin story reboot Joss Whedon pitched in December 2002, Warner Bros. hired Nolan in January 2003 to direct a new film. Nolan and Goyer began development on the film in early 2003. Aiming for a darker, more realistic tone compared to the previous films, a primary goal for their vision was to engage the audience's emotional investment in both the Batman and Bruce Wayne identities of the lead character. The film, which was principally shot in the United Kingdom, Iceland and Chicago, relied heavily on traditional stunts and miniature effects, with computer-generated imagery being used in a minimal capacity compared to other action films. Comic book storylines such as The Man Who Falls, Batman: Year One, and Batman: The Long Halloween served as inspiration.

Expectations for Batman Begins ranged from moderate to low, which originated from the poor reception of Batman & Robin that was credited with stalling the Batman film series in 1997. After premiering in Tokyo on May 31, 2005, the film was released on June 15, 2005. It received highly positive reviews from critics, who deemed the film an improvement over the Schumacher films. The film grossed over $371.9 million worldwide, becoming the ninth-highest-grossing film of 2005 and was the second highest grossing Batman film at the time behind Tim Burton's Batman (1989). Receiving a nomination for the Academy Award for Best Cinematography, the film elevated Bale to leading man status while it made Nolan a high-profile director.

Since its release, Batman Begins has often been cited as one of the most influential films of the 2000s. It was credited for revitalizing the Batman character in popular culture, shifting its tone towards a darker and more serious tone and style. The film helped popularise the term reboot in Hollywood, inspiring studios and filmmakers to revive franchises with realistic and serious tones. It was followed by The Dark Knight (2008) and The Dark Knight Rises (2012), with the three films constituting The Dark Knight Trilogy.

Plot
In Gotham City, after falling down a well and getting swarmed by bats, a young Bruce Wayne develops a fear of them. At the opera with his parents, Bruce becomes unsettled by performers masquerading as bats and asks to leave. Outside, mugger Joe Chill murders Bruce's parents in front of him. Bruce is raised by the family butler, Alfred Pennyworth.

Fourteen years later, Chill testifies against the mafia crime boss, Carmine Falcone, and is paroled. Bruce intends to murder Chill to avenge his parents, but one of Falcone's hitmen does so first. Bruce's childhood friend, Rachel Dawes, berates him for acting outside the justice system. After confronting Falcone, who says real power comes from being feared, Bruce spends the next seven years traveling the world, training in combat, and immersing himself in the criminal underworld.

In a Bhutan prison, he is approached by Henri Ducard, who recruits him to the League of Shadows, led by Ra's al Ghul. The League believes Gotham is beyond saving and intends to destroy it. After completing his training, Bruce rejects the League and its mandate that killing is necessary. He escapes, burning down their temple in the process. Ra's is killed by falling debris, while Bruce saves the unconscious Ducard. Intent on fighting crime, Bruce returns to Gotham and takes an interest in his family's company, Wayne Enterprises, which is being taken public by businessman William Earle. Company archivist Lucius Fox, a friend of Bruce's father, allows him access to prototype defense technologies, including a protective bodysuit and the Tumbler, an armored vehicle. Bruce poses publicly as a shallow playboy while setting up a base in the caves beneath Wayne Manor and taking up the vigilante identity of "Batman," inspired by his childhood fear, which he has now conquered.

Intercepting a drug shipment, Batman provides Rachel, now a Gotham Assistant District Attorney, with evidence against Falcone and enlists Sergeant James Gordon, one of Gotham's few honest police officers, to arrest him. In prison, Falcone meets Dr. Jonathan Crane, a corrupt psychologist who smuggled drugs into Gotham with his help. Donning a scarecrow mask, Crane sprays Falcone with a fear-inducing hallucinogen, driving him insane and transferring him to Arkham Asylum. While investigating Crane, Batman is ambushed by him and sprayed with the hallucinogen. Batman barely escapes and is saved by Alfred and Fox, who develop an antidote for the hallucinogen.

When Rachel accuses Crane of corruption, he reveals he has introduced his drug into Gotham's water supply and drugs her with the hallucinogen. Batman later subdues Crane and sprays him with his own chemical. While being interrogated, Crane claims to work for Ra's al Ghul. Batman evades the police to get Rachel to safety and administers the antidote. He gives her two vials: one for Gordon and the other for mass production. At Bruce's birthday party, Ducard reappears and reveals himself to be the true Ra's al Ghul. Having stolen a powerful microwave emitter from Wayne Enterprises, he plans to vaporize Gotham's water supply, rendering Crane's drug airborne and causing mass hysteria that will destroy the city. He sets Wayne Manor aflame and leaves Bruce to die, but Alfred rescues him. Ra's loads the emitter onto Gotham's monorail train to release the drug at the city's central water source. Batman rescues Rachel from a drugged mob and reveals his identity to her. He confronts Ra's on the train as Gordon uses the Tumbler's cannons to destroy a section of the track. Batman escapes the train and leaves Ra's to die as it crashes.

Bruce gains Rachel's respect. However, she refuses to be with him, promising they can be together when Gotham no longer needs Batman. Batman becomes a public hero. After purchasing a controlling stake in Wayne Enterprises, Bruce fires Earle and replaces him with Fox. Sergeant Gordon is promoted to Lieutenant, shows Batman the Bat-Signal, and tells him about a criminal who leaves behind Joker playing cards. Batman promises to look into it and disappears into the night.

Cast
A billionaire socialite who, after witnessing his parents' death in a mugging at age 8, travels around the world seven years before returning home to inherit his family company Wayne Enterprises whilst operating at night as a bat-masked vigilante bringing justice upon the criminal underworld of Gotham City. Bale was relatively unknown when cast. Before he was confirmed on September 11, 2003, having expressed interest in the role since Darren Aronofsky was planning his own film adaptation, Eion Bailey, Henry Cavill, Billy Crudup, Hugh Dancy, Jake Gyllenhaal, Joshua Jackson, David Boreanaz, Heath Ledger, who later played the Joker in The Dark Knight, and Cillian Murphy, who would later be cast as Dr. Jonathan Crane / Scarecrow, took interest in it as well. Josh Hartnett met with Nolan about the role, but decided against pursuing it. Bale, Bailey and Murphy auditioned using the Batman Forever sonar suit donated by Val Kilmer, but the cape was lost,    and Amy Adams served as the casting reader for the casting of Bruce Wayne / Batman in a favor to the casting director. Bale felt the previous films underused Batman's character, overplaying the villains instead. To best pose as Batman, Bale studied graphic novels and illustrations of the superhero. Director Nolan said of Bale, "He has exactly the balance of darkness and light that we were looking for." Goyer stated that while some actors could play a great Bruce Wayne or a great Batman, Bale could portray both radically different personalities. Since he had lost a great deal of weight in preparation for his role in The Machinist, Bale hired a personal trainer to help him gain 100 lb of muscle in the span of only a couple of months to help him physically prepare for the role. After realizing he went over by 30 lb, he lost the excess weight by the time filming began. Bale trained in Wing Chun Kung Fu under Eric Oram in preparation for the movie. A trusted butler to Bruce's parents, who continues his loyal service to their son after their deaths as his closest confidant. Nolan offered the role to Anthony Hopkins but he declined. Nolan went to Caine's country home to personally deliver him the script, telling what his role would be and describing Alfred as "Batman's godfather". Nolan felt Caine would effectively portray the foster father element of the character. Although Alfred is depicted in the film as having served the Wayne family for generations, Caine created his own backstory, in that before becoming Wayne's butler, Alfred served in the Special Air Service. After being wounded, he was invited to the position of the Wayne family butler by Thomas Wayne because, "He wanted a butler, but someone a bit tougher than that, you know?" The leader of the League of Shadows, an ancient society that uses chaos to punish the corrupt and decadent, who goes undercover as an associate of the League and trains Bruce in martial arts, later revealing himself in the film's climax. Writer David Goyer said he felt he was the most complex of all the Batman villains, comparing him to Osama bin Laden; "He's not crazy in the way that all the other Batman villains are. He's not bent on revenge; he's actually trying to heal the world. He's just doing it by very draconian means." Gary Oldman was first choice for the part, but ended up playing James Gordon instead. Guy Pearce, who collaborated with Christopher Nolan on Memento (2000), reported that the pair had discussions about him playing the role, but both of them decided that he was too young for the part. Viggo Mortensen was also considered for the role. Neeson is commonly cast as a mentor, so the revelation that his character was the main villain was intended to shock viewers. Bruce's childhood friend and love interest who serves as Gotham City's assistant district attorney and fights against corruption in the city of Gotham. Nolan found a "tremendous warmth and great emotional appeal" in Holmes, and also felt "she has a maturity beyond her years that comes across in the film and is essential to the idea that Rachel is something of a moral conscience for Bruce". One of the few uncorrupted Gotham City police officers, who is on duty the night of the murder of Bruce's parents and, in this way, shares a special bond with the adult Bruce and thus with Batman. Oldman was Nolan's first choice for Ra's al Ghul, but when Chris Cooper turned down the part of Gordon to spend time with his family Nolan decided that it would be refreshing for Oldman, who is renowned for his portrayals of villains, to play the role instead. "I embody the themes of the movie which are the values of family, courage and compassion and a sense of right and wrong, good and bad and justice," Oldman said of his character. He filmed most of his scenes in Britain. Goyer said Oldman heavily resembled Gordon as drawn by David Mazzucchelli in Batman: Year One. A corrupt psychopharmacologist working as Chief Administrator of Arkham Asylum. A specialist in the psychology of fear, he has secretly created a fear-inducing toxin and plots with Ra's al Ghul to expose the entire Gotham population. Nolan decided against casting an Irish actor like Murphy for Batman, before casting him as Scarecrow. Murphy read numerous comics featuring the Scarecrow and discussed making the character look less theatrical with Nolan. Murphy explained, "I wanted to avoid the Worzel Gummidge look, because he's not a very physically imposing man – he's more interested in the manipulation of the mind and what that can do." The most powerful Mafia boss in Gotham, who shares a prison cell with Joe Chill after he murdered Bruce's parents. Later, after having Chill murdered for his decision to testify against their relationship, he goes into business with Dr. Jonathan Crane and Ra's al Ghul by smuggling in Crane's fear toxins through his drug shipments over the course of several months so that they can be mixed in with the city's water supply. The CEO of Wayne Enterprises, who takes the company public in Bruce's long-term absence. A member of the League of Shadows assigned to impersonate Ra's al Ghul during Bruce's training. A high-ranking Wayne Enterprises employee demoted to working in the company's Applied Science Division, where he conducts advanced studies in biochemistry and mechanical engineering and supplies Bruce with much of the gear necessary to carry out Batman's mission. He is promoted to CEO when Bruce takes control of the company by the end of the film. Other cast members include Mark Boone Junior as Arnold Flass, Gordon's corrupt partner; Linus Roache as Thomas Wayne, Bruce's late father; Larry Holden as district attorney Carl Finch; Colin McFarlane as Gillian B. Loeb, the police commissioner; Christine Adams as Jessica, William Earle's secretary; Vincent Wong as an old Asian prisoner; Sara Stewart as Martha Wayne, Bruce's late mother; Richard Brake as Joe Chill, the Waynes' killer; Gerard Murphy as the corrupt High Court Judge Faden; Charles Edwards as a Wayne Enterprises executive; Tim Booth as Victor Zsasz; Rade Šerbedžija as a homeless man, who is the last person to meet Bruce when he leaves Gotham City, and the first civilian to see Batman, Risteárd Cooper and Andrew Pleavin as uniformed policemen, Jo Martin as a police prison official, and Shane Rimmer and Jeremy Theobald (the star and co-producer of Nolan's 1998 film Following) as Gotham Water Board technicians. Jack Gleeson, who had previously co-starred with Bale in 2002's Reign of Fire and later found fame for his role as Joffrey Baratheon in the HBO series Game of Thrones, appears as a young admirer of Batman who is later saved by him from Ra's al Ghul's men; Gleeson was cast at Bale's recommendation. Actors John Foo, Joey Ansah, Spencer Wilding, Dave Legeno, Khan Bonfils, Mark Strange, Grant Guirey, Rodney Ryan and Dean Alexandrou portray members of the League of Shadows. Hayden Nickel made his acting debut portraying James Gordon Jr.

Development
In January 2003, Warner Bros. hired Memento director Christopher Nolan to direct an untitled Batman film, and David S. Goyer signed on to write the script two months later. Nolan stated his intention to reinvent the film franchise of Batman by "doing the origins story of the character, which is a story that's never been told before". Nolan said that humanity and realism would be the basis of the origin film, and that "the world of Batman is that of grounded reality. [It] will be a recognizable, contemporary reality against which an extraordinary heroic figure arises." Goyer said that the goal of the film was to get the audience to care for both Batman and Bruce Wayne. Nolan felt the previous films were exercises in style rather than drama, and described his inspiration as being Richard Donner's 1978 film Superman, in its focus on depicting the character's growth. Also similar to Superman, Nolan wanted an all-star supporting cast for Batman Begins to lend a more epic feel and credibility to the story.

Goyer wanted to reboot the franchise; he and Nolan saw Batman as a romantic character, and Nolan envisioned a large, sweeping film like Lawrence of Arabia. Nolan did not have a problem with the studio's requirement that the film not be R-rated because he wanted to make the film that he wanted to see when he was 11 years old. His personal "jumping off point" of inspiration was "The Man Who Falls", a short story by Denny O'Neil and Dick Giordano about Bruce's travels throughout the world. The early scene in Batman Begins of young Bruce Wayne falling into a well was adapted from "The Man Who Falls". Batman: The Long Halloween, written by Jeph Loeb and drawn by Tim Sale, influenced Goyer in writing the screenplay, with the villain Carmine Falcone as one of many elements which were drawn from Halloween's "sober, serious approach". The writers considered having Harvey Dent in the film, but replaced him with the new character Rachel Dawes when they realized they "couldn't do him justice". The character was later portrayed by Aaron Eckhart in the 2008 sequel The Dark Knight. The sequel to Halloween, Batman: Dark Victory, also served as a minor influence. Goyer used the vacancy of Bruce Wayne's multi-year absence presented in Batman: Year One to help set up some of the film's events in the transpiring years. In addition, the film's Sergeant James "Jim" Gordon was based on his comic book incarnation as seen in Year One. The writers of Batman Begins also used Frank Miller's Year One plot device, which was about a corrupt police force that led to Gordon and Gotham City's need for Batman. Due to Batman's extensive rogues gallery over seventy years, Goyer and Nolan decided to use the Scarecrow and Ra's al Ghul as the film's villains, as both characters had not been featured in previous Batman films nor in Adam West's 1960s television series.

A common idea in the comics is that Bruce saw a Zorro film with his parents before they were murdered. Nolan explained that by ignoring that idea – which he stated is not found in Batman's first appearances – it emphasized the importance of bats to Bruce and that becoming a superhero is a wholly original idea on his part. It is for this reason Nolan believes other DC characters do not exist in the universe of his film; otherwise, Wayne's reasons for taking up costumed vigilantism would have been very different.

Filming
As with all his films, Nolan refused a second unit; he did this in order to keep his vision consistent. Filming began in March 2004 in the Vatnajökull glacier in Iceland (standing in for Bhutan). The crew built a village and the front doors to Ra's' temple, as well as a road to access the remote area. The weather was problematic, with 75 mph winds, rain, and a lack of snow. A shot that cinematographer Wally Pfister had planned to take using a crane had to be completed with a handheld camera.

Unlike Burton and Schumacher's Gotham City that did not exist in the real world, Nolan shot exteriors in London, New York, and Chicago as he wanted the city to seem recognizable. In seeking inspiration from Superman and other blockbuster films of the late 1970s and early 1980s, Nolan based most of the production in England, specifically Shepperton Studios. A Batcave set was built there and measured 250 ft long, 120 ft wide, and 40 ft high. Production designer Nathan Crowley installed twelve pumps to create a waterfall with 12000 impgal, and built rocks using molds of real caves. An airship hangar at Cardington, Bedfordshire was rented by Warner Bros. during April 2004 and, converted into a 900 ft sound stage, was where the slum-district of "the Narrows" and the feet of the monorails were filmed.

Mentmore Towers was chosen from twenty different locations for Wayne Manor, as Nolan and Crowley liked its white floors, which gave the impression of the manor as a memorial to Wayne's parents. The building chosen to represent Arkham Asylum was the National Institute for Medical Research building in Mill Hill, northwest London, England. The St Pancras railway station and the Abbey Mills Pumping Stations were used for Arkham's interiors. The Senate House of University College London was used for courtrooms. Some scenes, including the Tumbler pursuit, were filmed in Chicago at locations such as Lower Wacker Drive and 35 East Wacker. Authorities agreed to raise Franklin Street Bridge for a scene where access to the Narrows is closed.

Despite the film's darkness, Nolan wanted to make the film appeal to a wide age range. "Not the youngest kids obviously, I think what we've done is probably a bit intense for them but I certainly didn't want to exclude the sort of ten to 12-year olds, because as a kid I would have loved to have seen a movie like this." Because of this, nothing gory or bloody was filmed.

Music
The score for Batman Begins was composed by Hans Zimmer and James Newton Howard. Nolan originally invited Zimmer to compose the music, and Zimmer asked Nolan if he could invite Howard to compose as well, as they had always planned a collaboration. The two composers collaborated on separate themes for the "split personality" of Bruce Wayne and his alter ego, Batman. Zimmer and Howard began composing in Los Angeles and moved to London where they stayed for twelve weeks to complete most of their writing. Zimmer and Howard sought inspiration for shaping the score by visiting the Batman Begins sets.

Zimmer wanted to avoid writing music that had been done in earlier Batman films, so the score became an amalgamation of orchestra and electronic music. The film's ninety-piece orchestra was developed from members of various London orchestras, and Zimmer chose to use more than the normal number of cellos. Zimmer enlisted a boy soprano to help reflect the music in some of the film's scenes where tragic memories of Bruce Wayne's parents are involved. "He's singing a fairly pretty tune and then he gets stuck, it's like froze, arrested development," said Zimmer. He also attempted to add a human dimension to Batman, whose behavior would typically be seen as "psychotic", through the music. Both composers collaborated to create 2 hours and 20 minutes worth of music for the film, with Zimmer composing the action sequences and Howard focusing on the dramatic scenes.

Design
Nolan used the 1982 science fiction film Blade Runner as a source of inspiration for Batman Begins. He screened Blade Runner to Pfister and two others to show the attitude and style that he wanted to draw from the film. Nolan described the film's world as "an interesting lesson on the technique of exploring and describing a credible universe that doesn't appear to have any boundaries", a lesson that he applied to the production of Batman Begins.

Nolan worked with production designer Nathan Crowley to create the look of Gotham City. Crowley built a model of the city that filled Nolan's garage. Crowley and Nolan designed it as a large, modern metropolitan area that would reflect the various periods of architecture that the city had gone through. Elements were drawn from New York City, Chicago, and Tokyo; the latter for its elevated freeways and monorails. The Narrows was based on the slummish nature of the (now demolished) walled city of Kowloon in Hong Kong.

Tumbler
Crowley started the process of designing the Tumbler for the film by model bashing. Crowley used the nose cone of a P-38 Lightning model to serve as the chassis for the Tumbler's turbine engine. Six models of the Tumbler were built to 1:12 scale in the course of four months. Following the scale model creation, a crew of over 30 people, including Crowley and engineers Chris Culvert and Annie Smith, carved a full-size replica of the Tumbler out of a large block of Styrofoam in two months.

The styrofoam model was used to create a steel "test frame", which had to stand up to several standards: have a speed of over 100 mph, go from 0 to 60 mph in 5 seconds, possess a steering system to make sharp turns at city corners, and withstand a self-propelled launch of up to 30 ft. On the first jump test, the Tumbler's front end collapsed and had to be completely rebuilt. The basic configuration of the newly designed Tumbler included a 5.7-liter Chevy V8 engine, a truck axle for the rear axle, front tires by Hoosier (which are actually dirt racing tires used on the right rear of open wheel sprint cars), 4 rear 44/18.5-16.5 Interco Super Swamper TSL tires (44" tall, 18.5" wide, mounted on a 16.5" wheel) and the suspension system of Baja racing trucks. The design and development process took nine months and cost several million dollars.

With the design process complete, four street-ready race cars were constructed, with each vehicle possessing 65 panels and costing $250,000 to build. Two of the four cars were specialized versions. One version was the flap version, which had hydraulics and flaps to detail the close-up shots where the vehicle propelled itself through the air. The other version was the jet version, in which an actual jet engine was mounted onto the vehicle, fueled by six propane tanks. The visibility inside the vehicle was poor, so monitors were connected to cameras on the vehicle body. The professional drivers for the Tumblers practiced driving the vehicles for six months before they drove on the streets of Chicago for the film's scenes.

The interior of the Tumbler was an immobile studio set and not actually the interior of a street-capable Tumbler. The cockpit was oversized to fit cameras for scenes filmed in the Tumbler interior. In addition, another version of the Tumbler was a miniature model that was 1:6 scale of the actual Tumbler. This miniature model had an electric motor and was used to show the Tumbler flying across ravines and between buildings. However, the actual Tumbler was used for the waterfall sequence.

Batsuit

The filmmakers intended to create a very mobile Batsuit that would allow the wearer to move easily to fight and crouch. Previous film incarnations of the Batsuit had been stiff and especially restrictive of full head movement. Costume designer Lindy Hemming and her crew worked on the Batsuit at an FX workshop codenamed "Cape Town", a secured compound located at Shepperton Studios in London. The Batsuit's basic design was a neoprene undersuit, which was shaped by attaching molded cream latex sections. Christian Bale was molded and sculpted prior to his physical training so the team could work on a full body cast. To avoid imperfections picked up by sculpting with clay, plastiline was used to smooth the surface. In addition, the team brewed different mixtures of foam to find the mixture that would be the most flexible, light, durable, and black. The latter presented a problem, since the process to make the foam black reduced the foam's durability.

For the cape, director Christopher Nolan wanted to have a "flowing cloak... that blows and flows as in so many great graphic novels". Hemming's team created the cape out of their own version of parachute nylon that had electrostatic flocking, a process shared with the team by the British Ministry of Defence. The process was used by the London police force to minimize night vision detection. The cape was topped by a cowl, which was designed by Nolan, Hemming, and costume effects supervisor Graham Churchyard. The cowl was created to be thin enough to allow motion but thick enough to avoid wrinkling when Bale turned his head in the Batsuit. Churchyard explained the cowl had been designed to show "a man who has angst", so his character would be revealed through the mask.

Fight choreography
Fight choreographers for Batman Begins, Justo Dieguez and Andy Norman, trained actors and stunt performers using the Spanish Keysi Fighting Method, which itself gained fame after it was used in the film and its sequel, The Dark Knight; however, the method was modified in The Dark Knight Rises due to Batman's age and physical condition and in order to match Bale's fighting style. The method is a self-defense system whose training is based on the study and cultivation of natural instincts.

Visual effects
For Batman Begins, Nolan preferred traditional stuntwork over computer-generated imagery. Scale models were used to represent the Narrows and Ra's al Ghul's temple. There were, however, several establishing shots that were CG composite images, such as Gotham's skyline, exterior shots of Wayne Tower, and some of the exterior monorail shots. The climactic monorail sequence mixed live action footage, model work, and CGI. The bats depicted in the film were entirely digital (except in shots containing only one or two bats), as it was decided that directing large numbers of real bats on-set would be problematic; dead bats were scanned to create digital models. Locations and sets were recreated digitally so that the flying bats would not appear incongruous once incorporated into the finished film.

Context
2005 was expected by industry experts to underperform compared to 2004. Many attributed the slump to be a result of high ticket prices, marketing costs, DVD sales hitting record levels, and new technologies creating an incipient demand for movies delivered directly via the Internet, over-the-airwaves, satellite dish or cable set-top box. By the start of the theatrical summer in 2005 (May), the box office slumped for 11 consecutive weeks, with year-to-date ticket sales down 5.4 percent from last year even as ticket prices rose a moderate 3 percent, to around $6.40 on average, according to Exhibitor Relations. Theater attendance prior to the summer of 2005 declined about 8 percent.

Several films were projected to not only perform well at the box office, but also reverse the slump at the box office. Star Wars: Episode III – Revenge of the Sith was expected by the industry to be the top-grossing film of the summer due to being the final live action Star Wars film at the time. Other films that were expected to do well were Batman Begins, Madagascar, Mr. & Mrs. Smith, Fantastic Four, War of the Worlds, and Charlie and the Chocolate Factory.

Batman Begins was expected by industry experts to help reverse the box office slump in June. However, there were concerns over a possible soft opening for the film. The previous film, Batman & Robin, was widely panned by critics and was credited with stalling the franchise since 1997. Bale's lack of star power at the time and a lack of iconic villains such as the Joker and Penguin that were portrayed by A-list celebrities were seen as possible detachments from audiences. Some also expressed concerns that Holmes' involvement with the film could derail the film's financial prospect due to her high-profile relationship with Tom Cruise (whose film War of the Worlds opened the following weekend) after his controversial appearance on ''The Oprah Winfrey Show. ''

Theatrical
Warner Bros. held the world premiere for Batman Begins in Tokyo, Japan on May 31, 2005. The film opened on June 15, 2005, in the United States and Canada in 3,858 theaters, including 55 IMAX theaters.

Home media
The DVD of Batman Begins was released on October 18, 2005, in both single-disc and two-disc deluxe editions and also released on VHS and UMD Video formats. In addition to the film, the deluxe edition contained featurettes and other bonus materials. The edition contained a small paperback booklet, the first Batman story, featured in Detective Comics #27, as well as Batman: The Man Who Falls and an excerpt from Batman: The Long Halloween. Batman Begins achieved first place in national sales and rental charts in October 2005, becoming the top-selling DVD of the fourth quarter of 2005. The DVD grossed $11.36 million in rental revenue. The DVD held its position at the top of the sales chart for a second week, but fell to second place behind Bewitched on video rental charts. The film had brought in $167 million in DVD sales by August 2006.

Batman Begins was released on HD DVD on October 10, 2006. A Limited Edition Giftset of the film was released on DVD and Blu-ray on July 8, 2008, to coincide with The Dark Knight which hit theaters July 18, 2008. Due to the successful box office performance of The Dark Knight, the Batman Begins DVD saw an increase in both sales and rentals. Batman Begins was released on 4K UHD Blu-ray on December 19, 2017. It received a novelization written by Dennis O'Neil, and a comic book adaptation by Scott Beatty.

Box office
Batman Begins ranked at the top in its opening weekend, accumulating $48 million, which was seen as "strong but unimpressive by today's instantaneous blockbuster standards". The film's five-day gross was $72.9 million, beating Batman Forever (1995) as the franchise high. Batman Begins also broke the five-day opening record in the 55 IMAX theaters, grossing $3.16 million. Polled moviegoers rated the film with an A, and according to the studio's surveys, Batman Begins was considered the best of all the Batman films. The audience's demographic was 57 percent male and 54 percent people over the age of 25.

The film held its top spot for another weekend, accumulating $28 million in a 43 percent drop from its first weekend. Batman Begins went on to gross $205 million in North America and had a worldwide total of $371.8 million from its original release. It earned $1.6 million more from its 2012 re-release, bringing its lifetime worldwide total to $373.4 million. It is the fourth-highest-grossing Batman film,, behind Tim Burton's Batman, which grossed $411 million worldwide and also being surpassed by its sequels The Dark Knight and The Dark Knight Rises, both of which have grossed over $1 billion. Batman Begins averaged $12,634 per theater in its opening weekend. It was released in more theaters, but sold fewer tickets than the other previous Batman movies, with the exception of Batman & Robin. Batman Begins was the seventh-highest-grossing film of 2005 in the United States.

Critical response
Review aggregator Rotten Tomatoes gives Batman Begins an approval rating of based on  reviews, with an average rating of. The site's critical consensus reads, "Brooding and dark, but also exciting and smart, Batman Begins is a film that understands the essence of one of the definitive superheroes." At Metacritic, which assigns a weighted mean rating reviews, the film received an average score of 70 out of 100, based on 41 critics, which indicates "generally favorable reviews". Audiences polled by CinemaScore gave the film an average grade of "A" on an A+ to F scale. James Berardinelli applauded Nolan and Goyer's work in creating more understanding into "who [Batman] is and what motivates him", something Berardinelli felt Tim Burton's film had lacked; at the same time, Berardinelli felt the romantic aspect between Bale and Holmes did not work because the actors lacked the chemistry Christopher Reeve and Margot Kidder (Superman), or Tobey Maguire and Kirsten Dunst (Spider-Man) shared in their respective roles. According to Total Film, Nolan manages to create such strong characters and story that the third-act action sequences cannot compare to "the frisson of two people talking", and Katie Holmes and Christian Bale's romantic subplot has a spark "refreshingly free of Peter Parker/Mary Jane-style whining".

Los Angeles Times' Kenneth Turan, who felt the film began slowly, stated that the "story, psychology and reality, not special effects", assisted the darkness behind Batman's arsenal; he noted that Neeson and Holmes, unlike Bale's ability to "feel his role in his bones", do not appear to fit their respective characters in "being both comic-book archetypes and real people". The New Yorker's David Denby did not share Berardinelli and Turan's opinion. He was unimpressed with the film, when comparing it to the two Tim Burton films, and that Christian Bale's presence was hindered by the "dull earnestness of the screenplay", the final climax was "cheesy and unexciting", and that Nolan had resorted to imitating the "fakery" used by other filmmakers when filming action sequences. Michael Wilmington of the Chicago Tribune believed Nolan and Goyer managed to "comfortably mix the tormented drama and revenge motifs with light hearted gags and comic book allusions," and that Nolan takes the series out of the "slam-bang Hollywood jokefests" the franchise had drifted into. Comic book scribe and editor Dennis O'Neil stated that he "felt the filmmakers really understood the character they were translating", citing this film as the best of the live-action Batman films. In contrast, J. R. Jones, from the Chicago Reader, criticized the script, and Nolan and David Goyer for not living up to the "hype about exploring Batman's damaged psyche". Roger Ebert, who gave mixed reviews to the previous films, and claimed in his review for Batman Returns that he did not believe noir worked in superhero films, wrote this was "the Batman movie I've been waiting for; more correctly, this is the movie I did not realize I was waiting for". Giving it four out of four stars, he commended the realistic portrayals of the Batman arsenal – the Batsuit, Batcave, Tumbler, and the Batsignal – as well as the focus on "the story and character" with less stress on "high-tech action".

Like Berardinelli, USA Today's Mike Clark thought Bale performed the role of Batman as well as he did Patrick Bateman in American Psycho, but that the relationship between Bruce Wayne and Rachel Dawes was "frustratingly underdeveloped". Kyle Smith thought Bale exhibited "both the menace and the wit he showed in his brilliant turn in American Psycho", and that the film works so well because of the realism, stating, "Batman starts stripping away each layer of Gotham crime only to discover a sicker and more monstrous evil beneath, his rancid city simultaneously invokes early '90s New York, when criminals frolicked to the tune of five murders a day; Serpico New York, when cops were for sale; and today, when psychos seek to kill us all at once rather than one by one." In contrast, Salon.com's Stephanie Zacharek felt Nolan did not deliver the emotional depth expected of "one of the most soulful and tortured superheroes of all"; she thought Bale, unlike Michael Keaton who she compared him to, failed to connect with the audience underneath the mask, but that Gary Oldman succeeded in "emotional complexity" where the rest of the movie failed.

Film director Tim Burton—who had directed the 1989 Batman film and its first sequel—felt Nolan "captured the real spirit that these kind of movies are supposed to have nowadays. When I did Batman twenty years ago, in 1988 or something, it was a different time in comic book movies. You couldn't go into that dark side of comics yet. The last couple of years that has become acceptable and Nolan certainly got more to the root of what the Batman comics are about."

Impact
Batman Begins has been cited as one of the most influential films of the 2000s. On the film's 10th anniversary, Forbes published an article describing its lasting influence: "Reboot became part of our modern vocabulary, and superhero origin stories became increasingly envogue for the genre. The phrase "dark and gritty" likewise joined the cinematic lexicon, influencing our perception of different approaches to storytelling not only in the comic book film genre but in all sorts of other genres as well." Shawn Adler of MTV stated Batman Begins heralded a trend of darker genre films, that either retold back-stories or rebooted them altogether. Examples he cited were Casino Royale, as well as the in-development RoboCop, Red Sonja, and Grayskull. In 2012, Kevin Feige, film producer and president of Marvel Studios, stated, "Chris Nolan's Batman is the greatest thing that happened [to superhero films] because it bolstered everything." Filmmakers, screenwriters and producers who have mentioned Batman Begins or The Dark Knight Trilogy to describe their projects include:

 * Jon Favreau (Iron Man)
 * Edward Norton (The Incredible Hulk)
 * McG (Terminator Salvation)
 * Alan Taylor (Terminator Genisys)
 * Damon Lindelof (Star Trek, Star Trek Into Darkness)
 * Robert Downey Jr. (Sherlock Holmes)
 * Lorenzo di Bonaventura (G.I. Joe: The Rise of Cobra)
 * Hugh Jackman (X-Men Origins: Wolverine)
 * Matthew Vaughn (X-Men: First Class)
 * Rupert Wyatt (Rise of the Planet of the Apes)
 * Sam Mendes (Skyfall)
 * Alex Kurtzman (Van Helsing)
 * Gareth Edwards (Godzilla)
 * Marc Webb (The Amazing Spider-Man)
 * David Ayer (Suicide Squad)
 * Bryan Cranston (Power Rangers)
 * Adam Wingard (Death Note)
 * Patty Jenkins and Matthew Jensen (Wonder Woman)
 * James Mangold (Logan)
 * Simon Kinberg (Dark Phoenix)
 * Andrew Kosove (Blade Runner 2049)
 * Todd Phillips (Joker)
 * Cathy Yan (Birds of Prey)

Themes
Comic book writer and author Danny Fingeroth argues that a strong theme in the film is Bruce's search for a father figure, saying "[Alfred] is the good father that Bruce comes to depend on. Bruce's real father died before they could establish an adult relationship, and Liam Neeson's Ducard is stern and demanding, didactic and challenging, but not a father figure with any sympathy. If Bruce is anyone's son, he is Alfred's. [Morgan] Freeman's Lucius is cool and imperturbable, another steady anchor in Bruce's life." Blogger Mark Fisher states that Bruce's search for justice requires him to learn from a proper father figure, with Thomas Wayne and Ra's al Ghul being the two counterpoints. Alfred provides a maternal figure of unconditional love, despite the overall lack of focus on a mother figure in Bruce's life.

Fingeroth also argues that a major theme in the film is fear, which supports the story of Bruce Wayne becoming a hero. Director Christopher Nolan stated that the idea behind the film was "a person who would confront his innermost fear and then attempt to become it". Fingeroth referred to this film's depiction as "the man with fear—but who rises above it". The theme of fear is further personified by the Scarecrow. The film depicts how fear can affect all creatures regardless of might. Allusions to fear are seen throughout, from Bruce's conquering of his demons, to becoming Batman, to the Scarecrow and his deadly fear toxin. The macabre, distorted images presented in the Scarecrow's toxin-induced hallucinations also express the idea of terror to an extreme.

Critic Brian Orndorf considered Batman Begins "fierce" and "demonstrative in brood", giving the film an abundance of gravitas and energy. It strays away from the lighter fare of Joel Schumacher's 1997 Batman film, Batman & Robin, which contained camp one-liners throughout. The theme of fear is intensified with the help of the musical score by Zimmer and Howard, which also "eschews traditional heroic themes". Also contrary to previous Batman films, a psychological investigation of Bruce Wayne's split personality in the bat suit is only lightly touched upon. Orndorf noted that Bruce is a "character constantly striving to do the right thing, not worn down by incessant reexamination".

Sam Ruben

Samuel Ruben (born Charles Rubenstein; November 5, 1913 – September 28, 1943) was an American chemist who with Martin Kamen co-discovered the synthesis of the isotope carbon-14 in 1940.

Early life
Ruben was the son of Herschel and Frieda Penn Rubenstein – the name was officially shortened to Ruben in 1930. Young Sam developed a friendship with neighbor Jack Dempsey and became involved with a local boys' boxing club and later, when the family moved across the Bay to Berkeley, he was a successful basketball player at Berkeley High School (Berkeley, California). After achieving his B.S. in chemistry at the University of California, Berkeley, he continued his studies there and was awarded a Ph.D. in physical chemistry in May 1938. He was immediately appointed instructor in the chemistry department, and became an assistant professor in 1941.

Research
Ruben and colleague Martin Kamen, a University of Chicago Ph.D. and researcher in chemistry and nuclear physics working under Ernest O. Lawrence at the Berkeley Radiation Laboratory, set out to elucidate the path of carbon in photosynthesis by incorporating the short-lived radioactive isotope carbon-11 in their many experiments between 1938 and 1942. Aided by the concepts and collaboration of C. B. van Niel, at Stanford University's Hopkins Marine Station, it became clear to them that reduction of CO2 can occur in the dark and may involve processes similar to bacterial systems. This interpretation challenged the century-old Adolf von Baeyer theory of photochemical reduction of CO2 adsorbed on chlorophyll which had guided decades of effort by Richard Willstätter, Arthur Stoll, and many others in vain searches for formaldehyde.

In hundreds of experiments with carbon-11 produced from deuterons and boron-10 by Kamen in the Radiation Laboratory's 37-inch cyclotron, Ruben and Kamen, with collaborators from botany, microbiology, physiology and organic chemistry, pursued the path of carbon dioxide in plants, algae, and bacteria. Their results, confused by absorption of the products on proteinaceous residues, initially failed to reveal the path of carbon in photosynthesis but succeeded in exciting the interest of scientists worldwide in the search and revelation of metabolic processes, beginning a revolution in biochemistry and medicine.

Ruben's experiments using 'heavy water', H2^{18}O, to yield gas had shown that the oxygen gas produced in photosynthesis comes from water. With nuclear physicists' tenuous prediction of a "long-lived radioactive carbon isotope", Ruben and Kamen pursued several routes that could lead to identification of the carbon-14 isotope. After several failed attempts, Kamen collected the results of a 120-hour cyclotron bombardment of graphite and trudged in the rain with it to the "Rat House", adjacent both to the chemistry department and to the cyclotron, and Ruben's desk. At 8 am, February 27, 1940, Ruben demonstrated unequivocally that the radioactivity was from carbon-14.

Use of carbon-14 in tracer experiments was hindered by the difficulty measuring the weak beta emission of the radioactive decay and by the onset of World War II that shut off production of the isotope. In 1942 Ruben was assigned to work on war related research away from Berkeley. Further, Kamen was removed from his position at Berkeley due to allegations he was a security risk. Ruben fully realized the potential use of this isotope and was committed to working to elucidate the mechanism of photosynthetic carbon fixation using carbon-14. Instead, Ruben gave all his barium carbonate-14C to chemistry department faculty member Andrew Benson who began his long series of fixation experiments to determine the path of carbon in photosynthesis. Only in 1949 did chemist Willard Libby use it to invent radiocarbon dating.

Ruben's recruitment for research in the World War II wartime effort led him to interest in the mechanism of phosgene as a poisonous gas. With C-11 phosgene prepared by Benson, they studied the combination of phosgene with lung proteins. Following Benson's departure from Berkeley in July 1943, Ruben died September 28, 1943, after a disastrous exposure to phosgene in a laboratory accident the preceding day.

Sam Ruben married Helena Collins West, a fellow chemistry student, during his final semester as an undergraduate at UC Berkeley, on September 28, 1935. They had three children: Dana West Ruben (born November 11, 1938), George Collins Ruben (born April 29, 1941), who became a professor at Dartmouth College, and Connie Mae Ruben Fatt (born June 18, 1943).

Sikorsky CH-37 Mojave

The Sikorsky CH-37 Mojave (company designation S-56) is an American large heavy-lift military helicopter of the 1950s. It entered service as the HR2S-1 Deuce with USMC in 1956, and as the H-37A Mojave with the U.S. Army that same year. In the early 1960s the designation was standardized to CH-37 for both services, with the HR2S-1 redesignated as CH-37C specifically.

Developed in the early 1950s with its first flight in 1953, it filled a 1950 Navy requirement for an assault helicopter. The design includes a front loading ramp with side opening clam shell doors on the nose. It is powered by two radial piston engines. It served well into the 1960s in active military service including in Indochina before being replaced, and many ex-military models went onto civilian service in the 1970s. This was the biggest helicopter in the world to enter service at the time, and one of the earliest twin engine models. It was known for being noisy but earned a good reputation for reliability. The Navy also adapted it to carry a naval radar, with two entering service as HR2S-1W.

The design lead to a production attempt as the Westland Westminster in the United Kingdom; prototypes were produced, but it did not go into full production. The S-56 was also the basis for the S-60 Skycrane helicopter prototype.

Design and development
The S-56 came into being as an assault transport for the United States Marine Corps (USMC), with a capacity of 26 fully equipped Marines. An order for the aircraft was placed in 1951 using the U.S. Navy/U.S. Marine Corps designation of the time of HR2S. The first prototype, the XHR2S-1 flew in 1953 and production deliveries of the HR2S-1 began in July 1956 to Marine Helicopter Squadron One (HMX-1), with a total of sixty aircraft being produced.

It was called HR2S-1 Duece in the USMC service.

The United States Army evaluated the prototype in 1954 and ordered 94 examples as the CH-37A, the first being delivered in summer 1956. All Marine Corps and Army examples were delivered by mid-1960. Army examples were all upgraded to CH-37B status in the early 1960s, being given Lear auto-stabilization equipment and the ability to load and unload while hovering. In the 1962 unification of United States military aircraft designations, the USMC examples were redesignated from HR2S-1 to CH-37C.

At the time of delivery, the CH-37 was the largest helicopter in the Western world and it was Sikorsky's first twin-engine helicopter. Two Pratt & Whitney R-2800 Double Wasp radial engines were mounted in outboard pods that also contained the retractable landing gear. This left the fuselage free for cargo, which could be loaded and unloaded through large clamshell doors in the nose. The early models could carry a payload of either three M422 Mighty Mites (a lightweight jeep-like vehicle) or 26 troops. For storage, the main rotor blades folded back on the fuselage and the tail rotor mast folded forward on the fuselage.

The CH-37 was one of the last heavy helicopters to use piston engines, which were larger, heavier and less powerful than the turboshaft engines subsequently employed in later military helicopters. This accounted for the type's fairly short service life, all being withdrawn from service by the late 1960s, replaced in Army service by the distantly related CH-54 Tarhe and in the Marine Corps by the CH-53 Sea Stallion.

Four CH-37Bs were deployed to Vietnam in September 1965 to assist in the recovery of downed U.S. aircraft, serving in this role from Marble Mountain Air Facility until May 1967. They were very successful at this role, recovering over US$7.5 million worth of equipment, some of which was retrieved from behind enemy lines. The CH-37 was also used to recover film capsules descending from space by parachute.

A total of 154 were produced by the time production ended. Of those 94 were H-34A, and 90 H-34 were converted to H-34B (later CH-34A and B respectively). It was the largest piston powered helicopter.

 * Westland Westminster
 * Unable to get government support for licence production of the civil S-56, Westland Aircraft used the S-56 control systems, rotors and gearbox as the basis for the Westminster but used their own tubular frame and twin 2,900 hp Napier Eland turboshafts for power in a flying test rig. Due to vibration they changed to a six-bladed S-64 rotor. The private venture project was ended when Westland took over three British helicopter companies and their more advanced and funded projects.
