The Appearance of the Frontier Concept in the Iberian Peninsula: at the Crossroads

Philippe Sénac studied this question a number of years ago for Aragon, where the term appears for the first time in 1059, while I examined its appearance in Castile in a previous article 2. I will thus here only briefly outline the characteristics of the term's appearance in period documents. The term is thus documented in Aragon as early as 1059 in the testament of King Ramirez I 3 . The term appears three more times over the next few years, always concerning the frontier with Islam. Sénac argues on the one hand that this new expression did not necessarily designate a linear frontier, and on the other that geography could have played a role in the term's appearance, this since around 1060 "the territorial limits of Aragonese lands now coincided with the ridges of a chain of mountains reaching more than 2,000 meters and it is probable that this concordance played a decisive role in the emergence of this term" 4 . There was thus a certain linearity, though perhaps momentary, of the frontier that favored the term's appearance. In the rest of the Peninsula, the term appears much later. Other terms were used, such as fines, extremum, extremitas, confines, which more often designate more a territory than its limits, with the exception of limites 5 . Most of the time, however, recurring expressions evoke the juxtaposition of Muslim and Christian spaces: tam in partibus Christianorum quam Sarracenorum 6 , contra partes Maurorum 7 , ex parte Maurorum 8 , 1 The bibliography on the theme of frontera is long.

The twelfth-century Iberian Peninsula represents an excellent opportunity for studying the frontier phenomenon because of the presence of two different social and economic systems with their own specific ways of controlling people and lands. These two large ensembles were politically divided into smaller polities: a number of Christian kingdoms to the north, while in Muslim al-Andalus recurring episodes of territorial fragmentation had led to independent principalities centered on large cities. The frontier's unstable character itself led to permanent readjustments during a time of renewal for political thought in the Latin West, and the Iberian Peninsula was at the forefront in these changes. The Peninsula was a place of social and institutional innovations that answered the numerous problems arising from a context of fervent competition between Christian polities, almost permanent conflict (except during truces) with al-Andalus, demographic growth and efforts to colonize new lands. The Iberian Christian kingdoms in general and those along the frontier in particular were privileged destinations for many clerics and peasant farmers from France. This demographic growth led to a densification of existing settlements through urban growth or rural colonization, as well as the conquest of new territories at the expense of neighbors both Muslim and Christian.

A number of major events concerning the frontier occurred between the end of the 11 th and middle of the 13 th centuries. The emergence in sources, chronicles or official acts of the Latin neologism frontera coincided with the emergence or disappearance of kingdoms or polities. It was also at this time that the Iberian Peninsula's political and administrative configuration enduringly set, almost to the present day, though not without resistance. New players emerged linked to the specific needs of the frontier, replacing traditional actors. This article will attempt to show how the actions of these various protagonists led to a growing definition of frontiers in the Iberian Peninsula during this period.

terminos contra Sarracenos 9 . The frontier was born in fact from this juxtaposition: hos inquam terminus / et ultra terminus 10 .

Definite use of the term frontera did not spread throughout the Peninsula until the beginning of the 13 th century 11 . Indeed, for a number of years it did not appear in the documents of the Christian kingdoms, with the notable exception of Aragon which was in continuous relation, more or less conflictual, with the taifa 12 of Zaragoza 13 , then with the Almoravids and Almohads. The term next appears in 1171 in a donation by Fernando II to the Order of Santiago 14 , in 1181, in the expression habitatores villarum et oppidorum de frontaria, used by the Pope Lucius III, and in 1181 in Castile by King Alfonso VIII 15 . The frontiers thus designated are those of kingdoms, and the expressions ad defensionem et utilitatem regni mei […] in Sarracenorum frontaria, or in frontaria regnorum, even ad defensionem frontarie regni mei adversus mauros multiply over the course of the 13 th century 16 . They designate a space of a certain depth settled by gentes de frontaria, from whence it is possible to attack regions under Muslim control, but which are also vulnerable to attacks by troops from those same regions.

There are thus numerous differences for how the term frontera appears between Aragon and Castile-Leon. Later in the central region of the Iberian Peninsula, the neologism concerns military orders and contacts between their properties and Islam. The borders between the numerous different military Order lordships are never called frontera, only those in contact with al-Andalus. It is true that the military Orders, especially in Castile, had for their purpose 9 Donation from November 23, 1167 in Benavento by Ferdinand II of the villa of Alcántara to Armengol VII of Urgel: J.L.M. Rodríguez, Orígenes de la Orden Militar de Santiago (1170-1195), Barcelona 1974, doc. 36, pp. 208-209. 10 Alfonso VIII allotting territories in Calatrava: González, Alfonso VIII, II, doc. 534 (22 IX 1189, Toledo), pp. 915-917. The term Hispania is sometimes used for al-Andalus, in opposition to the fines Christianitatis. 11 The etymology of frontier refers to the idea of "facing" or "facing off". The Castilian version of Alfonso VIII's donation of the castle of Consuegra to the Hospitaller Order in 1183 (González, Alfonso VIII, II, doc. 409 [6 VIII 1183, Palencia], pp. 709-710) thus translates the term fronteria in the original Latin with a la frente de los moros: C. de Ayala Martínez, Libro de privilegios de la Orden de San Juan de Jerusalén en Castilla y León (siglos XII-XV), Madrid 1995, no 144, pp. 322-324: Dono itaque vobis et concedo castellum quod dicitur Consogra, in fronteria maurorum prope Toletum situm […]. 12 From the Arabic tâ'ifa, "party, faction". These independent principalities appeared in al-Andalus after the caliphal crisis at the beginning of the 11 th century, once again in the middle of the 12 th century during the collapse of the Almoravids and before the arrival of the Almohads, and finally in the 13 th century beginning in 1228, when the last Almohad caliph to reign over al-Andalus, al-Ma'mûn, left the Iberian Peninsula for Marrakesh. 13 The term reappears in the Ebro Valley over the course of the 12 th century: J.M. Lacarra, Documentos para el estudio de la Reconquista y repoblación del valle del Duero, I, Zaragoza 1982, no 22, pp. 36-37, and no 103 (dated from 1124), pp. 115-116, cited by P. Sénac, op.cit., p. 50. The term refers here to a previous period, quanto ibi tenebamus frontera ou quando ibi tenebamus fronteram, and thus seems to refer to the period when the term first appeared. 14 We should note how early these appearances are in regards to the explosion of donations in frontaria Sarracenorum over the course of the 1220s. The 1171 donation came at a time when the alliance between Leon and the Almohads was on its last legs, and was one of the first monarchical donations to the military Order of Santiago, only recently constituted along the frontier with Islam. 15 For example in the donation of the castle of Almofrag, quod est in ripa Tagi in frontera Sarracenorum: J.L.M. Rodríguez, Derechos eclesiásticos de la Orden de Santiago y distribución de los beneficios económicos (1170-1224), "Anuario de Estudios Medievales" XI (1981), pp. 247-275, espec. no 1 (23 X 1181), pp. 260-261 and C. de Ayala Martínez, Libro de privilegios..., no 144, pp. 322-324. The donation of the castle of Monfragüe to the recently created Order of Santiago, coinciding with the broken truce with the Almohads, confirms the frontier and anti-Muslim vocation of the military orders. The 1181 bull recalls a quarrel between Santiago and the bishopric over the collection of taxes. Lucius III enjoins the Spanish bishops and the archbishop of Toledo to respect the Order's privileges in regards to exemptions and immunities for churches built by the Order in unpopulated areas. The 1183 donation resembles the first in its structure, since it documents the donation of the castle of Consuegra to the Hospitaller Order north of Campo de Calatrava. 16 Diverse examples in: González, Alfonso VIII, III, doc. 1009 (8 I the defense of the kingdom's borders. The contrast between the term's use in monarchical or pontifical chancelleries and its total absence from private documents of the military orders speaks to the strong ties between monarchical territorial definitions and occurrences of the word frontera. Private acts, hundreds of them in the Spanish national archives, from the military Orders of Calatrava and Santiago, often document the limits of property in donations, sales, exchanges, dispute settlements between the Orders or with private persons or lordships, but never use the term frontera.

THE POLITICAL RECONFIGURATION OF THE IBERIAN PENINSULA IN THE 12 TH CENTURY AND CHANGES IN INFLUENTIAL PLAYERS

The seigniorial system in the Latin West framed how frontier lands were managed. Nevertheless, two principal types of protagonists are notable: the traditional actors of medieval society, the nobility and the Church, and specifically borderland actors, the concejos of the frontier and the military orders. Power over borderlands was not equally divided between these different lords, neither geographically nor chronologically.

TRADITIONAL ACTORS: THE CHURCH AND NOBILITY

The great nobility received numerous properties from lands recently conquered by Alfonso VI and Alfonso VII until the middle of the 12 th century, but their role diminished with the Iberian arrival of the Almohads in 1147. On the other hand, the Church maintained its importance throughout the period in question. For Castile-Leon, the archbishopric of Toledo's political, religious and ideological role was fundamental in the development of the Gothic myth of the Reconquista, but frontier sees such as Cuenca were likewise important17. Spanish bishops and archbishops intervened through the collection of tithes, the Church's monopoly of which was strongly contested by the other lords, in the ecclesiastical organization of territories -with the recurring question of Toledo's primacy and the redrawing of Iberian dioceses, no longer in east to west bands as in Roman times, but longitudinally to follow the Christian expansion into al-Andalus -and also military activities, since clerics, despite the Peace of God and Truce of God movements, often took up arms against the "infidels".

SPECIFICALLY FRONTIER PLAYERS: THE TOWNSMEN, OR CONCEJOS, AND MILITARY ORDERS

Though townsmen were certainly present in other regions of the Peninsula, and, in a different form, through the Latin West, the concejos of Transierra or the Douro valley received municipal charters, fueros, that gave them exceptional rights and privileges specifically tied to their place on the frontier, especially when compared with settlement and privilege charters issued elsewhere in the medieval West. The frontier townsmen's exceptional nature can be seen first of all in military activities, with the establishment for a time of a "popular" cavalry, and the organization of annual incursions into al-Andalus. Their rights were specifically adapted to the precarious conditions of the frontier, while legal and institutional innovations led to their presence there. Finally, a desire to survival united the inhabitants of the concejo, independent of other imperatives (political or religious). The frontier concejos were an original institution with a fundamental role in the birth of the Castile-Leon state, alongside the Church and military orders. The concejo model of development, however, was not adopted south of the Tagus River, reflecting changes after the 12 th century, when the possibilities for urban creations were limited by the intensity of confrontations and rougher geographic conditions between the Tagus and Sierra Morena. This explains why the Castile-Leon monarchs called on other forces to guard the borders of their kingdom.

The military Orders, along with the frontier concejos, constitute the other major type of specifically frontier protagonists. The first examples are the Templar and Hospital of Saint John Orders. While the Templars accepted to combat the Andalusi Muslims towards 1140 in exchange for a series of castles and a share of future conquests, the Knights Hospitaller gained only minor concessions. These "international" orders thus settled in the Peninsula before involving themselves in the conquest, which explains in large part the creation of "territorial" military orders, destined to combat within the Peninsula and not the Holy Land 18 . Indeed, the Knights Templar and Hospitaller used the Iberian Peninsula as a recruiting and financing base for operations in Palestine. It is for this reason that the Hispanic orders were created to explicitly fight against the Muslims and to defend the frontiers. This includes the orders of Calatrava, founded in 1158 by the king of Castile, of Santiago, recognized in 1170 by the king of Leon, and those of Alcántara and Avis.

THE MONARCHICAL RECOMPOSITION: BIRTH AND DISAPPEARANCE OF IBERIAN KINGDOMS

Contrary to what happened in the 10 th century in the Latin West, with the privatization of kingly rights (ost, money, taxes, justice) and the fragmentation of the royal domain to the benefit of territorial princes, the colonial powers that emerged in the Iberian Peninsula beginning in the 11 th century remained largely under the sovereigns. Those rulers delegated to the frontier seigneuries (individual or collective) only the right to build castles in the frontier regions and to conduct the ost against Muslim territories, while reserving for themselves the rights to mint coins and conduct justice. The 11 th to 13 th centuries were thus not a context of weakening monarchical power in Christian Iberia, but saw growing control for the rulers over men and lands with an internal competition that led during the 12 th century to the instability of existing borders. The county of Portugal thus became a new kingdom after the battle of Ourique in 1139, while the small kingdom of Navarra, far to the North and far from the Islamic frontier, was barely surviving, despite the extraordinary riches it gained from its place along the Compostela pilgrimage route. Those riches, in fact, drew the envy of Navarra's Castilian and Aragonese neighbors, as well as their recurring intervention, so that the small kingdom disappeared a number of times and was only able to survive through a lasting alliance with the Muslim rulers of al-Andalus. The shared frontier with the Muslim polities was thus at this time an asset for the monarchical powers in their effort to control their territories and subjects, and, inversely, the absence of a common border with al-Andalus was a handicap for the small kingdom of Navarra, despite its extreme wealth. 18 I am using here Carlos de Ayala's distinction between the orders of Santiago, Calatrava and Alcántara, which he qualifies as "territorial" in opposition to the Templars and Hospitallers, defined as "universal" and to later orders designated as "national": C. de Ayala, Las Órdenes militares en la Edad Media, Madrid 1998, pp. 8-16.

5/12 THE CONVERGING CONCEPTS OF TERRITORY, MEN AND CHRISTENDOM

The comparison of Arabic and Latin terminologies reveals the need for the West to create a new concept, frontera, and thus a modification of representations of self and the Other which accompanied the evolution of the term Christianitas. Heretofore, Christianitas had designated the Christian people. However, the notion was progressively territorialized to take on the sense of Christendom and designated those territories given by God to His people. This evolution took place in the social and ideological laboratory of the Iberian Peninsula, and was tied to the converging interests of the different protagonists of Mediterranean history.

THE POPE

The Pope had an indirect role in the Christian Iberian kingdoms. Since his spiritual authority extended over the territories held by Christians, his frontiers were those of Christendom, to be extended at the expense of the Infidels. Within Christendom, not only did he recognize the monarchical authorities who accepted his spiritual authority, but he was also the guarantor of internal borders, for which he sought to promote Christian peace. This led him in 1211 to obtain the participation of Navarra in the preparations for the Battle of Las Navas de Tolosa against the Almohads. That battle, which took place in 1212, saw the alliance of three kings (Castile, Aragon, Navarra) that had heretofore opposed each other. The Pope obtained Navarra's participation by guaranteeing its neighbors and competitors, Castile and Aragon, would thereafter respect its borders. He conceded legitimacy to those powers who respected these rules and condemned or excommunicated those who resisted, such as the king of Leon, allied to the Almohads since the 1170s.

In addition, the Pope supported international institutions, such as the military or monastic Orders, that contributed to emergence of the territorial idea of Christianitas by developing solidarities that transcended the borders of Christian kingdoms. The at least spiritual support offered to these military Orders, presented in pontifical documents, tended to make these institutions an instrument in the hands of the Popes. Though in the end this attempt failed, it still spread a unifying discourse within the Christian monarchies in regards to the alterity of Islam. The presence of papal delegates, the nomination of legates a latere, and the dispatch of recommending or condemning letters participated in this will to interfere in peninsular affairs. The pontificate of Honorius III stands out in this process19 . Innocent III's confirmation of the treaty of 1216 between the kings of Castile and Leon, even though the nobles of the two kingdoms had stood as guarantors, is another example of the Pope's means of intervention 20 .

The Pope thus imposed himself as mediator and guarantor between the Peninsula's Christian powers. He progressively became a protagonist in his own right, as shown by a letter from June 1250 in which the Almohad caliph, al-Murta á addressed Pope Innocent ḍ IV as "ruler of the kings of Christendom, respected by the nobles of the rūmiyya 21 community, head of Christian doctrine, the religious direction of which he has inherited, Pope Innocent"22 . It is difficult to measure the influence of pontifical interventions on the constitution of an image of the Other, and thus the representation of the separating frontier. We can only note that the entire pontifical epistolary production insists on the community of the faithful23 and the Otherness of the Sarracenorum24 . We can measure the influence of pontifical orders on political decisions in the Peninsula at one specific moment. Honorius III's bull of November 4 1220 was addressed to all the Christian Hispanic kings so that they would employ coreligionists, and not Jews, as ambassadors to "Miramamolin", the Prince of the Believers (amīr al-mu'minīn) 25 . Honorius III's advice stemmed from the principal that a Christian was less apt to betray than a Jew and seems to come from a desire to impose religious cohesion, the strongest possible, on the Peninsular monarchies, at least among the ruling classes26 . Nevertheless, the North African chronicler Ibn 'Idhârî writes that in 1221-1222, when the truce signed in 1215-1216 between Castile and the Almohads was renewed, the ambassador sent by the Castilian king Ferdinand III was Jewish. Thus, a year after the pontifical letter, the ruler of Castile had kept the same ambassador and afforded him the same confidence27 . We should note though that the papal letter contained no menace of excommunication in case of non-obedience.

THE MONARCHS OF THE IBERIAN PENINSULA

The expansion of territorial control by the Christian polities of the North and the process of "political differentiation" of the five kingdoms (Aragon, Castile, Leon, Navarra, Portugal) over the course of the 12 th century posed the crucial problem of delimitating "internal" borders. The failure of the eleventh-century Leonese imperial dream for unity is richly informative for this subject [START_REF]On the concept of Hispania and the stages in the development of the imperial ideal in the medieval Iberian Peninsula see J.A. Maravall Casesnoves[END_REF] . It established first of all the strength and identity of each of the peninsular kingdoms, especially Portugal. Secondly, Alfonso VI was able to claim an empire including not only Christian territories (counties or kingdoms), but also Muslim polities (through parias). Certain Arabic sources even call him Imbiratûr dhû-l-millatayn, "Emperor of the two religions" 29 . This would have been inconceivable for the 13 th century, and Alfonso X turned towards the Germanic Holy Roman Empire for inspiration [START_REF]Even though his claims remain more intra-peninsular than really Germanic, as shown by C. de Ayala, Directrices fundamentals de la política peninsular de Alfonso X[END_REF] . This failure consecrates and confirms the appearance of frontiers within Hispanic Christendom. The rulers of these emerging kingdoms likewise sought to expand their borders at the expense of their weaker neighbors (especially through matrimonial alliances). During periods of weakness in al-Andalus, they spread to the south. The 1157 Treaty of Sahagún between Castile and Leon is emblematic of later treaties of the same type, such as the Treaty of Tordesillas signed in 1494 between Spain and Portugal dividing lands to be discovered in the Atlantic Ocean. These treaties fixed borders between kingdoms, established them lastingly and guaranteed them in exchange for an agreement on the division of future riches from al-Andalus. The direct consequence of these treaties was a competition for the conquest of Muslim territories and the emergence of the southern borders of Portugal, Leon, Castile, and Aragon. For kingdoms without an "extensible" border, with no opening onto al-Andalus, like Navarre, the adopted solution was a rear alliance with the Almohads, then, thanks to pontifical mediation, the obtaining of strongholds and fortified relays in Aragon in exchange for the stability of its borders and an option on future gains from al-Andalus through booty. The last element in the monarchs' strategy to secure and so stabilize their borders resides in the distribution of frontier lands to institutions that we can anachronistically call "transnational", the military orders. These institutions were generally endowed on one side and the other of the internal frontiers of Christendom (to ensure non-aggression).

The 1158 Treaty of Sahagún between Sancho III of Castile and Ferdinand II of Leon foresaw in detail the sharing of the terra Sarracenorum [START_REF]On the divisional treaties prior to conquest[END_REF] , but a clause also provided that any acquisitions from Portugal would be shared equally through common accord [START_REF] González | [END_REF] . The basis for fixing borders was thus far from being exclusively religious. In addition, in the 1177 treaty signed at the siege of Cuenca between Castile and Aragon, the two kings agreed to help each other against Christians and Saracens, except against King Ferdinand II 33 . There does seem to have been a tendency towards solidarity between the Christian kingdoms, but exceptions were numerous. Nevertheless, there does seem to be a certain evolution in the exceptional clauses. Indeed, in a peace treaty signed at the beginning of the thirteenth century between Alfonso IX of Leon and Ferdinand III, a clause stipulated that, concerning the mauros, the help agreed on against omnes hominess de mundo would be subordinated to the expiration of truces Castile might have had with them. At the end of the foreseen period, Castile could help, as provided, Leon against the lands of Islam. The clause concerning previously signed agreements with Islam was frequent in these alliances, but in the present example it was stipulated, and this is the innovation, that those homines regis Castelle who so wished, despite the truce, to aid the king of Leon, could do so provided they sought their king's approval 34 . The idea of transversal solidarities between the Christian kingdoms thus emerged in parallel with the political reinforcement of the Christian monarchical borders and the entrenchment of territorial frontiers.

THE MILITARY ORDERS

The military orders, as professionals of war, sought revenue through a variety of means. Some, like the Order of Santiago, specialized in the redemption of captives, while others were granted lands in the hinterland of the kingdoms, far from Muslim incursions, where they collected seigniorial dues common in the Christian West. On the other hand, Orders could likewise seek to generate revenue through booty and domains acquired at the expense of the Muslims. It is difficult to know if at first the Order of Santiago was not established by Leon to protect its borders with the Christian kingdoms of Portugal and Castile 35 . What is sure, though, is that the struggle along the Muslim frontier quickly became the principal vocation for these institutions. Endowed with frontier territories in the different kingdoms, they were the guarantors of the borders between the Christian kingdoms and participated in the emergence of the notion of Christendom and the fixation of borders between kingdoms. The fact that these institutions had interests spread throughout the different Christian kingdoms ranked them among the first to become the guarantors of the borders between them 36 . This was the case in 1181, for example, with the treaty of Medina de Rioseco between Ferdinand II of Leon and Alfonso VIII of Castile. A number of frontier castles thus fell to the head of the Order of Santiago, Pedro Fernández, and the prior of the Knights Hospitaller, Pedro de Areis, pro tenenda et obseruanda pace inter nos et filios nostros et filias in perpetuum 37 .

THE TOWNSMEN

Unlike the deterritorialized military orders, the townsmen had a base around which their municipal territory was organized. Jurisdictional disputes were numerous between townsmen and neighboring lords for the collection of dues. As long as they bordered al-Andalus, these townsmen kept mobile borders to the south. But with the conquest of Toledo in 1085, al-Andalus became simply a source of booty, whence the frequent incursions they carried out, of which some ended very badly. At the same time, these concejos, such as Ávila, Segovia, Salamanca, Coria, Talavera etc., intensified the territorial control of their alfoz, an Arabic term (al-hawzh), with the installation of villages, the aldeas (from the Arabic al-day a ʽ ) that led to the lasting entrenchment of their municipal borders.

These municipal institutions initially developed over the course of the 11 th century in demographically depressed regions that were gradually settled by groups from the North, during a time of peace tied to the political crisis in al-Andalus -this was the time of the taifas (1031-1090), when the Cordovan Umayyad Caliphate fragmented into autonomous and rival polities. The local rights that developed thanks to monarchical action in the form of fueros spread, contributing to the diffusion throughout the kingdom of written laws that could be granted or confirmed by any lord, secular or ecclesiastical, be they bishop, abbey, king or count. Specialists do not agree on the origin of the fueros. Some historians insist on a royal origin for the fueros, others on a more regional origin for the municipal laws in the twelfthcentury Iberian kingdoms of Castile, Aragon, Leon, and Portugal 38 . The important distinction between the two means that either monarchical space was undergoing a process of undeniably centralizing organization, or it was an autonomous process of development in the context of permanent danger resulting from the presence of Muslim armies. These fueros simply confirmed an existing ensemble of practices and customs, making clear reference to the character of the inhabitants already in place and establishing contractual norms between them and the king. These charters thus did not create townsmen, but they did codify the link they maintained with the king. There in fact seems to have been a conjunction between the two 35 J.L.M. Rodríguez, Orígenes de la Orden militar de Santiago (1170-1195), Barcelona 1974, pp. 7-10 and A. Forey, The Military Orders from the Twelfth to the Early Fourteenth Centuries, London 1992, p. 29. We should note, however, that the 1171 charter granted by Ferdinand II, though it does not completely contradict the thesis of these authors, does explicitly tie one of these very first donations to the Order of Santiago to the frontera Sarracenorum. 36 The transversal character of the military Orders appears in the fact that there was not a perfect coincidence between their internal hierarchical organization and the political divisions of the Peninsula. García Larragueta notes that from the second half of the 12 th century and until the 13 th , there was a "castellan de Amposta" with jurisdiction in Catalonia, a "prior" of the Navarra-Aragonese territories and another "prior" with jurisdiction in Castile, Leon, and Portugal: S. García Larragueta, La Orden de San Juan en la crisis del imperio hispánico, "Hispania" XII (1952) 49, pp. 483-524. 37 phenomena, a conjunction that would explain the success of the development of the fueros and concejos [START_REF] Powers | Frontier Competition and Legal Creativity: A Castilian-Aragonese Case. Study Based on Twelfth-Century Municipal Military Law[END_REF] .

THE CHURCH

Ecclesiastical structures in the lives of frontier townsmen complicate any interpretation we might have of the fueros. After an 11 th century in which Christian expansion was marked by the phenomenon of municipal freedoms, the second quarter of the 12 th century, beginning with the personal reign of Alfonso VII (1127-1157), inaugurated a process of progressive limitation of freedoms granted, of reaffirmation for monarchical power, and, simultaneously, a reinforcement of the cohesion and dynamism for the concejos. Indeed, on townsmen's territories institutions with privileges, exemptions and diverse rights developed. These institutions directly rivaled the municipal monopoly. The arrival of new dioceses, for example, of a foreign frontier clergy composed essentially of Francs, and the collection of tithes in the alfoz (municipal territory) churches all reduced the margin of autonomy for the urban knights.

In fact, after an initial resistance, the reinforcement of the Episcopal figure and the guarantee of his autonomy by election by the cathedral college accompanied the autonomy of the knights developed by the concejiles communities and gave him even more importance [START_REF] Villar | La Extremadura castellanoleonesa. Guerreros, clérigos y campesinos[END_REF] . The territorial structures that developed in this way were very coherent, and ecclesiastical and military hierarchies united in defending them against the expansionist tendencies of other concejos, secular lordships and ecclesiastical neighbors.

These hierarchies which were parallel and interdependent, secular and ecclesiastical, found in the institution of the annual raids against Muslim al-Andalus the foundations of their functional, economic and social distinction. In conjunction, we should note the increasingly important role played by the ecclesiastical authorities in the preparation of expeditions and ceremonies celebrating the victorious return of troops, including the Te Deum and diverse processions symbolically bringing together the battlefield and praises for the Lord, warriors and clerics, booty and the glory of God.

Clearly establishing episcopal limits was thus very important at this time. Rivalries between neighboring dioceses for the definition of respective limits expressed themselves through disputes over collecting tithes. Thus, at the same time new territories were being conquered from Islam, an ensemble of maneuverings sought to assure the financial independence and wealth of the new "restored" centers. The different strategies advanced sought to recall the dioceses during late antiquity. In fact, the liberties taken in regards to those ancient lines was such that the claims made led less to a real "restoration" of the classical dioceses, some of which disappeared or were replaced by others, than to the emergence of what Peter Linehan has called the "Gothic myth", and more generally the ideology of the Reconquista, the "legitimate" recuperation of territories temporarily and brutally captured by the Muslim infidels. The archbishop of Toledo, aspiring to the leadership of the peninsular bishops because of his primatial title, was one of the principal beneficiaries of this strategy for restoring the Visigothic-era episcopal structures.

THE RESISTANCE OF THE NOBLES

Lastly, we should note certain specific forms of independence that emerged in the border regions. This was essentially a Christian phenomenon, the product of nobles in open conflict with their rulers. Examples include the Cid, at the end of the 11 th century in Valencia, on the border between Castile and Aragon, or, in the second half of the 12 th century, Giraldo Sempavor, the "Portuguese Cid", between Leon and Portugal, Pedro Fernández de Castro, between Leon and Castile, or the Azagra Navarrese family who founded an independent polity between Castile and Aragon in the area around Albarracín. In fact, these nobles created, in the interstices of the expanding Christian kingdoms, on the frontiers separating kingdoms competing for the Muslim territories of al-Andalus, independent territories, even if it meant allying with Muslim rulers to maintain their independence against the growing monarchical power of the Iberian kingdoms 41 .

CONCLUSION

The Iberian Christian communities developed empirically adapted and efficient responses, military, demographic or ideological, to the specific problems presented by the frontier. The military orders are a good example of the transversal solidarities that contributed to the emergence of a front against Islam. The use of existing orders (Templars and Hospitallers) and the creation of new orders, such as Calatrava, Santiago, Alcántara, etc., as guardians and spearheads of the frontier were the principal innovations of the 12 th century. These greatly contributed to the emergence of Christendom as an entity that was politically and religiously opposed to demonized Islam. In addition, the emergence of a new conception of the frontier likewise seems to have owed much to the Papacy, and in particular to the Holy War mentality that developed at the same time as the Crusades. Through equivalencies that recognized the remission of sin for fighting against Islam on the Peninsula and in the Holy Land, the different pontiffs tended to bring together the eastern and western fronts in people's minds 42 . The enemy was the same, the frontier was Christendom's, and the combat pro Christianorum finibus dilatandis [START_REF]See Innocent III's 1206 bull exhorting the faithful to give alms to the Order of Calatrava to send knights to the Holy Land during the period when[END_REF] . In multiplying indulgences for combat in the Holy Land and Iberian Peninsula alike, pontifical intervention tended to make the frontiers of

They were then regularly renewed. In his article Réforme, reconquista, croisade. L'idée de reconquête dans la correspondance pontificale d'Alexandre II à Urbain II, "Cahiers de civilisation médiévale" XL (1997), p. 317-335, Jean Flori contests the vision presented by Marcus Bull in his Knightly Piety and the Lay Response to the First Crusade. The Limousin and Gascony (c. 970 -c. 1130), Oxford 1993: "Le but que poursuit Urbain II est à l'évidence de faire renoncer les Espagnols à leur voeu de croisade en Orient et à le commuer en combat contre les Sarrasins en Espagne. Il était donc nécessaire d'assimiler étroitement les deux théâtres d'opérations militaires et les récompenses que l'on pouvait y acquérir, comme le fait plus nettement encore Pascal II (Epistolae, PL, 163, col. 45) quelques années plus tard en interdisant toute participation des Espagnols à la croisade pour les diriger vers le combat contre les Maures" (p. 333).

This term is preferable to "Roman" used by Tisserant and Wiet in their translation, since the bilâd al-Rûm originally designated Byzantium, then extensively the countries of Europe peopled by Christians.

Paul Rousset notes the term Christianitas was frequently used in the chronicles of the First Crusade, while it is practically absent from other contemporary sources: idem, La notion de Chrétienté aux XI e et XII E siècles, "Le Moyen Âge" LXIX (1963), pp. 191-203 and R.

For example, in a bull by Celestin II from October 31, 1196, the Pope recalls what a Christian king should do: Christianis quibus viriliter suum prestare debuerat auxilium et favorem, in opposition to the actual actions of the excommunicated Leonese king and his alliance with the Muslims: multipliciter infert molestiam et gravamen...

This measure coincides with decisions taken at the Fourth Lateran Council concerning Jewish and Muslim minorities, in particular those living near the frontier. Decisive measures were taken under the pontificate of Innocent III, 1198-1216, according to J.M. Powell, The Papacy and the Muslim Frontier, in: Muslims under latin rule 1100-1300, ed. by J.M. Powell, Princeton 1990, pp. 175-203, p. 192.

Peter Linehan defends the same thesis in his History and the Historians of Medieval Spain, Oxford 1993, that pontifical influence was weak over the Peninsular Church, which was more loyal to the monarch to which it was attached than to Rome. This thesis is also developed in his The synod of Segovia (1166), "Bulletin of Medieval
