Independence struggle against Córdoba, Kingdom of Asturias-León
The Visigoth Pelagius was supposedly elected king (or prince) by his followers in 718. He scored a defensive victory at the Battle of Covadonga, which in retrospect has been interpreted as the beginning of the Reconquista. However, it was a private dispute with the Muslim governor in charge of Asturias that gave rise to the rebellion. More tangible is King Alfonso I († 757), who created a belt of devastation between his kingdom and the Muslim territory through murders. Under his son Fruela I began the Repoblación, the repopulation of depopulated areas by Christians. Galicia was also subjugated.
Alfonso II. (791-842) resumed the conquests. The capital was now Oviedo, founded in 761. Under Alfonso III. (866-910), Asturias achieved its greatest expansion and temporary suzerainty over the Muslim south. His three sons divided the kingdom among themselves and the partial kingdoms of León, Galicia and Asturias were formed. In 924 they were reunited as the Kingdom of León.
The first king of León was García I. He married a daughter of the Castilian Count Nuño Fernández, who in 910 had supported García and his two brothers Fruela and Ordoño in a rebellion against their common father. García received León, his brothers Ordoño Galicia and Fruela Asturias. The childless García was succeeded by his brother Ordoño II, who had been sent to Saragossa to be educated by the Banu Qasi. He had the cities of Évora and Mérida sacked. Córdoba was defeated in the battle of San Esteban de Gormaz in 917, but the Christians were defeated in the battle of Valdejunquera in 920. A counterattack led to the occupation of La Rioja and the conquest of the territories around Nájera and Viguera in Navarre. Ordoño II, who had summoned the Counts of Castile but they did not show up, summoned them to Tejares and had them summarily murdered.
He was succeeded by his brother Fruela II, which would later lead to a succession dispute with the latter's son Alfonso Froilaz, because Ordoño had three sons named Sancho Ordoñez, Alfonso and Ramiro. Alfonso became king in 925 after the three brothers ousted the heir, his brother Sancho Ordóñez became king of Galicia from 926 to 929, and his other brother Ramiro ruled Portugal. The latter, also called Ramiro the Great, formed an alliance with Navarre and Aragon that defeated the Caliph's forces in the Battle of Simancas in 939. The southern border of the Empire was moved from the Duero to the Tormes.
But he could not prevent Castile from becoming independent. Rodrigo, the first Count of Castile, conquered Amaya and the territory of La Burega and Oca in 860, until he controlled the Pancorbe pass leading to the Ebro Valley. Then followed the expansion into the Duero basin. Count Diego-Rodréguez founded Burgos in 884. The conquest of the Riója by Sancho García I, King of Navarre, secured the eastern border around 920.
In 931, the counties into which Castile had been divided until then were united by Count Fernán González, who made the county under the suzerainty of the Kingdom of León independent in 944. With the support of León, he was able to repel attacks from Córdoba until then, after which he succeeded in conquering Osma and Simanca. He allied himself with the Caliph against León, but he was stopped by Sancho the Fat in 966. He left the county to his son García Fernández (970-995), who faced final attacks from Córdoba but was able to extend his dominion northward. His son and successor Sancho García temporarily allied himself with Córdoba and intervened there after the death of al-Mansur in 1008.
In 955 Ordoño III of León sent an army to Lisbon, after which an agreement was reached between him and the Caliph. He married Urraca Fernández, daughter of Fernán González, Count of Castile, but he later disowned her because her father was allied with Sancho I, who disputed the throne with him. In fact, he succeeded him on the throne after his death in 956. Two years after his coronation, he was again deposed by nobles led by Fernán González, Count of Castile. In exile with his grandmother Toda of Navarre, he won the support of Abd ar-Rahman. He conquered Zamora in 959 and regained his throne. However, there was a break with the Caliph and subsequently an alliance with Navarre.
Sancho was finally poisoned in 966 and his five-year-old son Ramiro III succeeded him on the throne. His aunt Elvira Ramírez, who assumed the title of king for the time, and his mother, Teresa Ansúrez took over the governance.
Vermudo II, son of Ordoño III and king of Galicia since 982, overthrew the young king in 984. Under the protection of Córdoba, he managed to reconquer Zamora, but this left him dependent on the support there in the fight against Castile. Córdoba gained a kind of suzerainty over León, whose troops did not leave until 987. Almansor, the ruler of Córdoba, then destroyed Coimbra. In addition, Moorish troops conquered Gormaz and Cluni (Coruña del Conde) in 994, Astorga in 996, and they sacked Santiago de Compostela in 997.
The king was succeeded in 999 by his five-year-old son Alfonso V, who was under the guardianship of his mother Elvira and Count Menendo González. León, destroyed by Almansor, was repopulated. In 1020 the Fueros, the customary laws of the historical territories, were adopted there by León.
While the Caliphate was crumbling, conflicts between the northern kingdoms were coming to a head. In 1029, the Castilian Count García Sanchez II visited León to marry Sancha, the king's daughter. Once there, however, he was murdered by members of the Vela family in revenge for an insult. Since he died without descendants, the King of Navarre, Sancho III, attacked Castilian territory to enforce his rights acquired through marriage with Munia, the sister of the slain. He assumed the title of Count of Castile. At the same time, Sancho had the Vela executed. Finally, Sancho's son, Ferdinand I, was made Count.
Recolonization (repoblación)
Repoblación, which was partly spontaneous, was already promoted by the counts in the Duero Basin. Thus, in addition to free settlers, village communities (comunidades de aldea) existed there, many of which were based on kinship. The emergence of large latifundia therefore occurred much later in Castile than in León or Galicia. This was less true, however, of the strong power and property concentrations of the counts around Lara and Burgos. Monasteries also acquired extensive estates.
In this process, dependent peasant groups appeared less than, for example, the commendation to any lord (behetría, derived from Latin benefactoria). People who were in possession of weapons or a horse could still easily rise to the nobility as infanzónes. This caballería villana is considered indicative of the social mobility of early Castile.
The counts, whose offices had become hereditary, were in a strong position vis-à-vis the king. While in León the legal norms laid down in the Liber iudiciorum applied, in Castile a customary oral tradition prevailed. This was based on the wisdom of the count's court days or on the fazañas of legendary judges of the past.
Union of Asturias-León and Castile under Ferdinand I. (from 1035/37), victory over Navarre (1054)
After the barely adult King of León Vermudo III failed to regain the territories lost to Navarre, the claim to the throne together with the conquered territories passed to his sister Sancha after his death. She, in turn, ceded her rights to her husband Ferdinand I. He was the second son of King Sancho III of Navarre and had been King of Castile and Navarre and now also King of León since 1035 and 1037 respectively.
The regional power thus created was relieved by the disintegration of the caliphate, and at the same time it intensified contacts with the rest of Western Europe. Thus, the Benedictine order spread, the pilgrimage route to Santiago de Compostela gained great importance. In addition, Ferdinand had the legal traditions collected.
His brother García IV of Navarre invaded Castile with Moorish allies in 1054, but he died in a battle at Atapuerca, as a result of which Ferdinand also won the part of Navarre lying on the right bank of the Ebro. From 1058 he succeeded in conquering the cities of Viseu as well as Lusitania up to the Mondego. Several Muslim kings had to pay tributes (parias) for his protective rule from 1055.
Before his death, Ferdinand divided his states among his three sons in such a way that Sancho received Castile, Alfonso León and Asturias, García Galicia and Portugal. The pariahs were also divided, so that Sancho II received the pariahs of Saragossa, Alfonso VI those of Toledo and Garcia those of Badajoz and Seville.
Intensified Reconquista, Western Europeanization, setback by Almoravids
With the division of the Parias, the direction of expansion was set, but disputes among the brothers delayed the conquest. Alfonso became king of Leon and Asturias in 1065, but his brother Sancho II, who had inherited Castile, drove him out of his domain after the death of their common mother Sancha. Alfonso then fled to the Taifa kingdom of Toledo. When Sancho was assassinated in 1072, Alfonso returned to Leon and was also recognized as king in Castile. He promoted the cities and the church system he organized according to the principles of the Cluniac-Gregorian reform, with close ties to Rome.
Alfonso intensified the pressure on the Taifareiche from 1076. He called himself Adephonsus Imperator Toletanus Magnificus Triumphator in memory of the conquest of Toledo of 1085, but also Imperator Totius Hispaniae and divinely appointed ruler over all the Nationes of Spain. The title of Imperator Totius Hispaniae remained in use from 1086 to 1157.
But Alfonso's army was defeated by the Almoravids in the Battle of Sagrajas in 1086. This ended the expansion to the south, especially since the Almoravids subjugated all the Taifas, thus eliminating the revenues to the Parias. The lords of the vast Berber Empire defeated Alfonso at Consuegra in 1097 and at Ucles in 1108.
Secession of Portugal, Queen Urraca, fight against Almoravids and Aragón
Alfonso died in 1109, after his son Sancho had perished at Ucles in 1108 and he had designated his daughter Urraca's son, another Alfonso, as his successor. Urraca, who belonged to the French Capetians on her mother's side, advanced to become the possible heir to the throne in 1090 in the absence of male heirs. A few years later, her cousin Henry of Burgundy was married to her younger half-sister Theresa. Raimund was appointed Count of Galicia by Alfonso VI for this purpose. After the birth of the Infante Sancho Alfónsez in 1093, Urraca's and Raimund's prospects of succession to the throne diminished.
In order to secure the southwestern border against the Almoravids, Raimund was endowed in May 1093 with the territory south of Galicia, the territory of the County of Portugal; however, he lost Lisbon to the Almoravids as early as 1094. In 1097, Alfonso VI granted the County of Portugal to Henry of Burgundy.
Only the government in the county of Galicia could Urraca continue in her name. The death of her half-brother Sancho placed her back at the center of succession considerations in 1108. Probably in August 1108, Urraca was betrothed to King Alfonso I "the Warrior" of Aragon. However, Sancho III of Navarre was their common great-grandfather, a kinship proximity that aroused the disapproval of the clergy led by the Archbishop of Toledo. Moreover, this marriage led to a deepening of the intra-family rift between Urraca and her brother-in-law Henry of Burgundy. Nevertheless, in May 1109 she was proclaimed heiress by her father. On July 22, one day after her father's funeral, Urraca deeded "Ego Urraka dei nutu totius yspanie regina." To affirm her sole rule, from 1110 she expanded her title with the imperial character held by the kings of Leon in "Vrracha, Dei gratia regina et imperatrix Yspanie".
But neither did the pope recognize their marriage, nor did the great ones accept a foreign mistress. On October 26, 1111, Urraca was defeated in the Battle of Candespina, but she managed to break the enemy alliance by drawing Henry to her side. She then had her son proclaimed king in Santiago de Compostela on September 19, 1111, as Alfonso VII, who was thus set up as a counter-pretender to Alfonso I of Aragon. The latter occupied both Toledo and León. In 1112 Urraca took the offensive and was able to confine her husband in Astorga, but Abbot Pontius of Cluny, appearing as papal legate, announced the annulment of their marriage. With this, the alliance finally broke apart.
In order to stabilize the border province of Zamora against Almoravid attacks, Urraca settled the Knights Hospitaller order in León in 1116. She reached a settlement with her former husband, with Alfonso renouncing all lordship rights in León and Castile. Resistance to Urraca's government now came from her half-sister Theresa, who called herself "Queen of Portugal" from November 1117.
Around the same time, the Almoravids attacked the County of Portugal. Urraca took advantage of this to regain Zamora and Toro, which she had once had to cede to Henry of Portugal. As a result of the peace with Aragon, Urraca was able to re-establish her rule in the area south of the Duero River and enter Toledo with her son on November 16, 1117, where he was proclaimed Emperor over all of Spain.
In 1117, Urraca's lover, the Castilian Count Pedro Gonzáles de Lara, became her first advisor. She deepened her ties to the House of Lara, one of the five most important Castilian families, by marrying her half-sister Sancha to her lover's brother. However, a Leónese noble group rose up against the growing influence of the Castilians at the royal court in 1119. The differences between Urraca and her Leónesian vassals were settled by September. In the face of her vassals, she received support from Pope Calixtus II, a brother of her first husband.
Now Urraca's rule was consolidated to the extent that its army could proceed against Theresa, who had been independent since 1109. It was victorious at Tui. In Braga, she was able to receive the submission of her nephew Alfonso Enríquez and the Portuguese nobility.
However, Archbishop Diego Gelmírez and the Galician nobility allied with him secretly made a pact with Theresa. When Urraca had him imprisoned in 1120, there was a popular uprising, and when Count Pedro Froilaz recruited an army against her, joined by her son, she had to release the archbishop. Against her, the Archbishop and Count Pedro Froilaz also raised an army, which again included her son. Urraca had to recognize the archbishop again in all the rights of rule in Santiago de Compostela. However, in agreement with the papal legate, he continued to pursue the deposition of Urraca and the enthronement of her son. Against this, however, Urraca obtained the support of Pope Calixtus II, who curtailed Diego Gelmírez's power by appointing the archbishop of Braga as supreme metropolitan over the bishoprics of Portugal and Galicia and by installing Archbishop Bernardo of Toledo as primate of the Church of all Spain. In the meantime, Theresa had once again gained an independent dominion in southern Galicia since 1121.
Imperial coronation of Alfonso VII. (1135), Union of Catalonia and Aragon (1134), Kingdom of Portugal (1139)
After a protracted war, which had already been started by his mother Urraca, who died in 1126, Alfonso VII stood his ground against his stepfather and retained Castile, Leon, Asturias and Galicia in the partition of 1127; he only ceded his share of Navarre, Álava, Vizcaya and Guipúzcoa to Aragón in the Peace of Támara. On May 26, 1135, he had himself crowned Emperor of all Spain in Léon.
However, after the death of Alfonso I of Aragon in 1134, the emperor had to accept the union of Catalonia and Aragon, as well as the restoration of the independence of Navarre. In Portugal, Alfonso, Teresa's son, assumed the title of king in 1139. This fact had to be recognized by Alfonso VII in 1143, albeit as an integral part of the Empire.
In 1146, the conquest of Córdoba succeeded. Shortly thereafter, the Almoravids, themselves beset by the Almohads, also lost Calatrava and Almería. However, the Almohads soon reconquered Córdoba. The division of the inheritance of Castile and León-Galicia among his sons Sancho III and Ferdinand II again divided the regional power.
Time of the five kingdoms
In León, Ferdinand II. (1157-1188) became king, followed by Alfonso IX (until 1229). The five Christian kingdoms were opposed by the Almohads, a cohesive empire that was able to consolidate itself until 1172. The five kingdoms were able to compensate for this imbalance of power by mobilizing citizen militias of urban conséjos, brotherhoods (cofradías) and orders of chivalry. The latter included the Order of Alcántara in León since 1156, the Order of Calatrava in Castile since 1157, and the Order of Saint James in both kingdoms since 1170.
In 1158, Sancho III died in León and Ferdinand assumed guardianship of his minor son Alfonso VIII. He invaded Castile and henceforth called himself King of Spain. In 1162 he conquered Toledo; in the same year, after the death of Raimund Berengar IV of Barcelona, he assumed guardianship of the latter's son and thus power in Aragon. His influence over Portugal grew in 1165 through his marriage to Urraca, a daughter of Afonso I. As a result of a dispute over Badajoz, war broke out with Portugal in 1168, from which Ferdinand, who had allied himself with the Almohads in 1169, emerged victorious. A second war with the Portuguese ended in 1177 with his victory at Argannal. But in Castile he increasingly lost influence. As early as 1166, the Castilian nobility recaptured Toledo. A war against Castile that began in 1178 dragged on until 1183.
Land development, Cortes of León (1188), first university (1219), victory over Almohads (1212)
Alfonso IX of León pursued an extensive repopulation and city-foundation policy; he also weakened the nobility by supporting the cities against them. One of his central innovations was the convening of a curia regis, in which representatives of the cities participated for the first time. It was from here that the Cortes began. The Cortes of León of 1188, which were supposed to protect against the abuse of power and arbitrariness, were compared to the Magna Charta. Unlike in Aragon, the Cortes (from 1217 in Valladolid) never succeeded in limiting the king's power to any great extent.
Foreign policy is linked to the incessant conflicts with Alfonso VIII of Castile. Alfonso IX even joined forces with the Almohads against the Castilian after the Battle of Alarcos, which resulted in his excommunication. With the marriage between the León and Berenguela of Castile, the battles ended for the time being. However, Pope Innocent III excommunicated the couple for being too close, which led to the resumption of the war. Accordingly, Alfonso IX of Leon was not involved in the victory at Las Navas de Tolosa against the Almohads. On the contrary, he attacked Castilian territory, but also took the opportunity to occupy Muslim cities such as Mérida and Badajoz. The knightly orders conquered other cities, so that the road to Seville was almost clear. Finally, in 1219, the University of Salamanca was founded, the oldest university in Spain and one of the oldest universities in Europe.
The victor of the battle at Las Navas de Tolosa of July 16, 1212, which in retrospect was decisive, was King Alfonso VIII of Castile, who led a coalition with Aragon, Portugal and Navarre against the Almohads. Even though the numbers of battle participants, which were supposed to underline the enormous importance of the battle, have since been reduced - Joseph F. O'Callaghan estimates the number of combatants involved on both sides in each of these battles at no more than 3,000 to 5,000 men - Pope Innocent III had succeeded in establishing a true crusading mentality on the peninsula for the first time.
Union of León and Castile (1230), Conquest of Seville (1248)
Ferdinand III, the son of Alfonso IX of León and Berenguela of Castile, became king of Castile after the death of his uncle Enriques I in 1217 - against the opposition of a noble and urban opposition under the imperial administrator Álvaro Núñez de Lara - and also of León after the death of his father in 1230. The empire was no longer divided and became indivisible with the consolidation of the Córtes in the 14th century.
Ferdinand, after several victories over the fragmented Muslim empires, especially at Jerez de la Guadiana in 1233, won the city of Córdoba in 1236. Ten years later followed the conquest of Jaén, in 1248 fell the kingdom of Seville, in 1250 Cadiz. Only the Emirate of Granada, founded in 1247, continued to exist until 1492.
The repopulation, now considered an imperial task, was intensified, with the king's followers and the bishops being given extensive territories. Numerous Moors left the country. Livestock, especially sheep, played an increasing role in the settlement (privileges of the Mesta, 1270-1273). The adoption of urban social forms, the stronger enforcement of market mediation and the money economy, and also the intensification of Mediterranean trade were largely taken over by Castile from the Muslim cities. But the primacy of religious policy, with recourse to imagined Visigothic traditions, now took precedence. Cistercians, Franciscans and Dominicans were encouraged. They were joined by Trinitarians and Mercedarians, who specialized in ransoming prisoners.
Ferdinand endowed several bishoprics, founded the Cathedral of Toledo, earned merits in legislation through the Código de las Partidas, completed by his son, and the translation of the Code of Laws applicable to the Moors of Córdoba. In terms of foreign policy, he involved himself and his family in the world of European states through marriages to Norway, England, France and the Empire, the latter bringing about claims to Sicily, but especially to the kingship as well as the Roman emperorship.
"Translator school" and national languages, legislation, imperial policy of Alfonso X.
The "School of Translators of Toledo" was a tradition of translation activity beginning in the 12th century, not an institution. Through contact between Mozarabic and Jewish people who knew Arabic and Latin authors, there was a transfer of knowledge promoted by episcopal or royal initiative. The first phase, lasting from about 1130 to 1187, was characterized by Archbishop Raimund of Toledo. Scientific and philosophical writings that had been translated from Greek into Arabic under the Abbasids were translated, as well as Arabic writings, such as those on astronomy and mathematics. In 1142, the Abbot of Cluny, Petrus Venerabilis, came to Spain and commissioned a translation of the Koran, which was completed in 1143 by the Englishman Robert of Ketton, the Croatian Hermann of Carinthia, the Castilian Petrus Alfonsi, and the Saracen Mohammed, and revised by the Abbot's secretary, Peter of Poitiers. New translation initiatives came from Alfonso X and his court, where now the focus was no longer on the translation into Latin, but into Castilian, and here especially the dialect of the Toledan court played a normative role.
Alfonso X, king of León and Castile from 1252 to 1282, was the first son of Ferdinand III the Saint and Elizabeth, a daughter of the German king Philip of Swabia. He promoted astronomy and the recognition of Ptolemaic cosmology, and between 1252 and 1270 he had the Ptolemaic planetary tables improved, which were called Tabulae Alphonsinae after him.
Alfonso, himself a poet, is also considered the founder of Castilian national literature. He had his historiographers write an Estoria de España and a History of the World in Castilian from about 1270 onward, and had documents drawn up in the national language. He also commissioned many works, such as the Cantigas de Santa Maria, 427 songs in Galician, the lyrical language of the time. But above all, he directed the compilation of the law book begun by his father, the Livro de las Legies, later called Las Siete Partidas or simply Partidas.
Alfonso, like other European rulers, was an exponent of an imperial policy based on kinship and the claims to titles and dominions derived from it. His descent from the Hohenstaufen dynasty through his mother Elizabeth gave him the opportunity to claim King Conrad IV's duchy of Swabia after his death in 1255, to have himself elevated to emperor by the Ghibellines of Pisa in March 1256, and to run for king. But in 1265 the pope directed the ambitions of Charles of Anjou, whose mother Blanka of Castile was the daughter of Alfonso VIII, to southern Italy, which thwarted Franco-Castilian plans. Alfonso then tried to raise the necessary funds to carry out a campaign in Rome to obtain the imperial crown, a crown he renounced only in 1275.
The Castilian nobility resisted the king's imperial plans and centralization efforts by forming alliances with the Muslims of southern Spain and with James of Aragon, even though the latter was Alfonso's father-in-law. Nevertheless, he put down the Mudéjares rebellion in Murcia on Alfonso's behalf to prevent Alfonso from supporting the Muslim population of Valencia in return.
Alfonso's far-reaching marriage plans with his northern neighbor initially failed. In 1275, this led to a war with France. After the end of the war, Alfonso initiated a crusade and conquered Jerez, Medina-Sidonia, San Lucar, Cadiz, part of the Algarve and united Murcia with Castile. In the end, only Tarifa, occupied in 1292, remained Castilian. As early as the Treaty of Monteagudo of 1291, "spheres of interest" were agreed between Aragon and Castile with regard to the Maghreb. Aragon, which had maintained diplomatic and trade relations with the Hafsids in Tunisia and the Abdalwadids in Algeria since about 1250, claimed prerogatives there, while Castile did the same in Morocco's Merinid Empire. Moreover, the Merinids had refused to conclude a peace and trade treaty with Aragon in 1276. In 1286, when the two Iberian powers were at war, Aragon tried to establish an alliance with the Merinids against Castile, but this too was rejected. The Merinids remained neutral, as did the Iberian Nazarites.
Economic crisis and revolts, Merinids and Granada, assertion of royal power (1348)
Between about 1275 and 1325, Castile experienced a severe social and economic crisis. Agricultural production and population declined. At the same time, the Cortes, nobility, ecclesiastical institutions faced the royalty, which tried to break the regional powers. After the conquests came to a conclusion, the nobles sought new revenues, but the royal administration had concentrated them in a separate financial administration. Although the powerful noble families achieved a shareholding, unlike Aragon they did not form a unity and so they did not succeed in forcing contractual rights from the king. Hermandades, alliances of cities, appeared from 1295 to 1302 and from 1313 to 1325. In the cities, families of caballeros came to power, against which the civic community, the común, was defeated.
Alfonso XI defeated many of the old nobleza vieja families. He remained neutral in the Hundred Years' War, allying himself with the caballero nobility and the hidalgos. The latter exercised power in the city councils in the 1330s and 1340s. Beginning in 1342, he imposed a general excise tax, the alcabala, then a reorganization of the sale of salt and a levy on livestock. But above all, in 1348, against the regional and legal fragmentation, he enforced the primacy of royal law by means of the Ordenamiento de Alcalá.
Dispute over Portugal, Coinage Policy, Rise of New Families, Occidental Schism
Pedro I (1350-1369) sought the help of England against Enrique of Trastámara - he had assassinated the legitimate heir to the throne and placed himself on the throne - while Enrique relied on France from 1366. After his victory, Enrique II. (1369-1379) reaffirmed the permanent Castilian-French alliance.
His successor intervened in the succession struggles in Portugal after the death of Ferdinando I (1383). The latter had not recognized Enrique of Trastámara as king of Castile and instead made his own claims to the throne. But in the Peace of Alcoutim, the Portuguese had to renounce all claims to the Castilian throne. He also undertook to marry one of Enrique's daughters. Instead, however, he married Leonore Teles de Menezes, whereupon Enrique attacked Portugal and sacked Lisbon in 1373. Portugal, in turn, allied itself with England, which also made claims to the Castilian throne. Portugal thus became a sideshow in the Hundred Years' War between England and France. However, since England did not send troops as promised, Ferdinando was forced to make peace in the Treaty of Santarém in 1373. In 1381 he attacked Castile again, but after the Portuguese fleet was destroyed, he had to ask for peace again. Ferdinando, who had no male heirs, had to consent to the marriage of his daughter to the new Castilian king, John I, thus reaffirming Castile's hereditary claims. However, John of Avis, an illegitimate half-brother of Ferdinando, took power and, having repelled Castilian claims by winning the Battle of Aljubarrota in 1385, had himself crowned the new king.
In Castile, royal power was further strengthened. The Consejo real took on its final form, a supreme court was created with the Real Audiencia, and the Contadurías Mayores emerged as the supreme authority for financial administration. But it was not until the reign of Henry III. (1390-1406), a certain stability of the currency and the reorganization of finances could be achieved.
In times of crisis, the Cortes met frequently, but the calming of the situation and the consolidation of new high noble families - they in particular benefited from the Trastamara's assumption of power - prevented the Cortes representatives from having a say in matters of treaty. When, during the Occidental Schism, which lasted from 1378 to 1418, Castile was part of the Avignon obedience, the royalty increasingly claimed rights in filling vacant bishoprics.
Assertion of royal power, union with Aragon
Henry III of Castile died in December 1406, and during the minority of his son John II of Castile, his mother Catherine of Lancaster and his uncle Ferdinand of Antequera ran the affairs of state. This dual regency divided the country into two camps. After Ferdinand died in 1416 and Catherine in 1418, the archbishop of Toledo, Sancho de Rojas, arranged for the king to be declared of age in 1419 on the occasion of his marriage to Marie of Aragon.
But now there was a confrontation with the Castilian nobility as well as with the sons of his uncle Ferdinand I, the Infantes de Aragón. Around 1430, with the help of Álvaro de Luna, John was able to prevail against Ferdinand's sons. After John's victory against the Emirate of Granada in the Battle of La Higueruela in 1431, a short-term peace was confirmed by the marriage of John's son Henry to Blanka of Aragon, the daughter of his adversary. However, this marriage was later dissolved. It was not until 1445 that Álvaro de Luna, the king's favorite from 1422 to 1453, achieved a victory, but this by no means ended the disputes. In these struggles, the nobility aimed to commit the kings to government programs they had devised, to occupy the highest offices in the administration, and to increase their own revenues. At the same time, they undermined the influence of the cities' representatives in the Cortes and sought to enlist the lower urban nobility as patrons. Under Henry IV (1454-1474), the power of the nobility reached its peak.
However, internal conflicts led to civil war from 1465, which culminated in the War of the Castilian Succession from 1474 until the party that brought Isabella I to the throne prevailed. Although kingship prevailed in Castile in 1480, the nobility retained privileges and influence. The queen now dominated the Cortes and the cities. Through the marriage between Isabella and Ferdinand of Aragon in 1469, after Ferdinand's reign in the lands of the Crown of Aragon, the most powerful kingdoms of the peninsula were ruled in a personal union. The population of Castile had grown to about 4.3 million inhabitants.
