The Crown of Castile, as an historic entity, is usually considered to have begun in 1230 with the third and almost definitive union of the monarchies of kingdoms Castile and Toledo in one hand, and the kingdoms of Leon and Galicia in other hand, and with the union of their parliaments a few decades later. In 1217, Ferdinand III was crowned King of Castile and Toledo, and 13 years after (1230), he usurped the crown of Leon and Galicia to their heirs (Sancha and Dulce); however, to reduce his titulation, he is most known as Ferdinand III of Castile and sometimes of "Castile and Leon".
The Kingdom of León arose out of the Kingdom of Asturias. The Kingdom of Castile appeared initially as a county of the Kingdom of León. From the second half of the 10th century to the first half of the 11th century it changed hands between Leon and the Kingdom of Navarre. In the 11th century it became a kingdom in its own right.
and united twice previously:
Ferdinand III received the Kingdom of Castile from his mother, Queen Berengaria of Castile, in 1217, and the Kingdom of León from his father (Alfonse IX of León) in 1230. From then on the two kingdoms were united under the name of the Kingdom of León and Castile, or simply as the Crown of Castile. Ferdinand III later conquered the Guadalquivir Valley, while his son Alfonso X conquered the Kingdom of Murcia from Al-Andalus, further extending the area of the Crown of Castile. Given this, the kings of the Crown of Castile traditionally styled themselves "King of Castile, Leon, Toledo, Galicia, Murcia, Jaén, Cordoba, Seville, and Lord of Biscay and Molina," among other possessions they later gained. The heir to the throne has been titled Prince of Asturias since the 14th century.
Almost immediately after the union of the two kingdoms under Ferdinand III, the parliaments of Castile and León were united. It was divided into three estates, which corresponded with the nobility, the church and the cities, and included representation from Castile, León, Galicia, Toledo, Navarre and the Basque provinces. Initially the number of cities represented in the Cortes varied over the next century, until John I permanently set those that would be allowed to send representatives (procuradores): Burgos, Toledo, León, Sevilla, Córdoba, Murcia, Jaén, Zamora, Segovia, Ávila, Salamanca, Cuenca, Toro, Valladolid, Soria, Madrid and Guadalajara (with Granada added after its conquest in 1492).
Under Alfonso X, most sessions of the Cortes of both kingdoms were held jointly. The Cortes of 1258 in Valladolid comprised representatives of Castile, Extremadura and León ("de Castiella e de Estremadura e de tierra de León") and those of Seville in 1261 of Castile, León and all other kingdoms ("de Castiella e de León e de todos los otros nuestros Regnos"). Subsequent Cortes were celebrated separately, for example in 1301 that of Castile in Burgos and that of León in Zamora, but the representatives demanded that the parliaments be reunited from then on.
Although the individual kingdoms and cities initially retained their individual historical rights—including the Old Fuero of Castile (Viejo Fuero de Castilla) and the different fueros of the municipal councils of Castile, León, Extremadura and Andalucía—a unified legal code for entire new kingdom was created in the Siete Partidas (c. 1265), the Ordenamiento de Alcalá (1248) and the Leyes de Toro (1505). These laws continued to be in force until 1889, when a new Spanish civil code (the Código Civil Español) was enacted.
In the 13th century there were many languages spoken in the Kingdoms of León and Castile among them Castilian, Leonese, Basque and Galician. But throughout the century Castilian gained more and more prominence as the language of culture and communication. One example of this is the 'Cantar de Mio Cid'.
In the last years of the reign of Ferdinand III Castilian began to be used to certain types of documents, such as the Visigothic Code, then the basis of the legal code for Christians living in Muslim Cordova, but it was during the reign of Alfonso X that it became the official language. Henceforth all public documents were written in Castilian, likewise all translations of Arabic legal and government documents were made into Castilian instead of Latin.
Some people think that the substitution of Castilian for Latin was due to the strength of the new language, whereas others consider that it was due to the influence of Hebrew-speaking intellectuals who were hostile towards Latin, the language of the Christian Church.
Furthermore, in the 13th century many Universities were founded like the Leonese Salamanca and the Castilian Estudio General of Palencia were the among the first universities in Europe.
Castilian was eventually carried to the Americas and, outside of Latin America, is usually called Spanish. In the Spanish-speaking countries, Castilian refers to the dialect of Spain, analogously to British English in the United States.
On the death of Alfonso XI a dynastic conflict started between his sons, the Infantes Pedro and Henry, Count of Trastámara, which became entangled in the Hundred Years' War. Alfonso XI had married Maria of Portugal with whom he had his heir, the Infante Pedro. However, the King also had many illegitimate children with Eleanor of Guzman, among them the above-mentioned Henry, who disputed Pedro's right to the throne once the latter became king.
In the resulting struggle, in which both brothers claimed to be king, Pedro allied himself with Edward, the Prince of Wales, "the Black Prince." In 1367 the Black Prince defeated Henry II's allies at the Battle of Nájera, restoring Pedro's control of the kingdom. The Black Prince, seeing that the king would not reimburse his expenses, left Castile. Henry, who had fled to France, took advantage of the opportunity and recommenced the fight. Henry finally was victorious in 1369 in the Battle of Montiel, in which he killed Pedro.
In 1371 the brother of the Black Prince, John of Gaunt, 1st Duke of Lancaster, married Constance, Pedro's daughter. In 1388 he claimed the Crown of Castile in the name of his wife, the legitimate heir according to the Cortes de Seville of 1361. He arrived in A Coruña with an army and took the city. He then moved on to occupy Santiago de Compostela, Pontevedra and Vigo. He asked John I, Henry II's son, to give up the throne in favor of Constance.
John declined but proposed that his son, the Infante Henry, marry John of Gaunt's daughter Catherine. The proposal was accepted, and the title Prince of Asturias was created for Henry and Catherine. This brought an end to the dynastic conflict, strengthened the House of Trastámara's position and created peace between England and Castile.
During the reign of Henry III royal power was restored, overshadowing the much powerful Castilian nobility. In his later years Henry delegated some of his power to his brother Ferdinand of Antequera, who would be regent, along with his wife Catherine of Lancaster, during the childhood of his son Prince John. After the Compromise of Caspe in 1412, Ferdinand left Castile to become king of Aragon.
Upon the death of his mother John II, at the age of 14, took to the throne and married his cousin Maria of Aragon. The young king entrusted his government to Álvaro de Luna, the most influential person in court and allied with the lesser nobility, the cities, the clergy and the Jews. This brought together the mutual dislikes of the king shared by the greater Castilian nobility and the Aragonese infantes, sons of Ferdinand of Antequera, who sought to control the Castilian crown. This eventually led to war in 1429 and 1430 between the two kingdoms. Álvaro de Luna won the war and expelled the Aragonese Infantes from Castile.
Henry IV unsuccessfully tried to re-establish the peace with the nobility that his father had shattered. When his second wife, Joan of Portugal, gave birth to Princess Joanna, it was claimed that she was the result of an affair of the Queen with Beltrán de la Cueva, one of the King's chief ministers.
The King, besieged by riots and the demands of the nobles, had to sign a treaty in which he named as his successor his half-brother Alfonso, leaving Joanna out of the line of succession. After the death of Alfonso in an accident, Henry signed the Treaty of the Bulls of Guisando with his half-sister Isabella in which he named her heiress in return for her marrying a prince chosen by him.
In October 1469 Isabella and Ferdinand, heir to the throne of Aragon, married in secret in the Palacio de los Vivero in Valladolid. The consequence was a dynastic union of the Crown of Castile and Crown of Aragon in 1479 when Ferdinand ascended to the Aragonese throne. This union however was not effective until the reign of his grandson Charles I. Ferdinand and Isabella were related and had married without papal approval. Although Isabella wanted to marry Ferdinand, she refused to proceed with the marriage until she received a papal dispensation. Consequently, Ferdinand's father forged a papal dispensation for the two to marry. Isabella believed that the dispensation was authentic and the marriage went ahead. A genuine papal dispensation arrived afterwards. Later Pope Alexander VI bestowed upon them the title of the Catholic Monarchs.
Henry IV, half brother of Isabella, considered the marriage of Ferdinand and Isabella as breaking the treaty of Tratado de los Toros de Guisando under which Isabella would ascend to the Castilian throne on his death only if her suitor was approved by him. Henry wanted to ally Castile with Portugal or France rather than Aragon. He therefore decided to name his daughter Joanna as heiress to the throne rather than Isabella. When he did in 1474 the War of the Castilian Succession broke out over who would ascend to the throne. It lasted until 1479 when Isabella and her supporters came out victorious.
After Isabella's victory in the civil war and Ferdinand's ascension to the Aragonese throne the two crowns were united under the same monarchs. However, this was only a personal union and both kingdoms remained administratively separate, each maintaining its own identity and laws; both parliaments remained separate, the only common institution would be the Inquisition. Despite their titles of "Monarchs of Castile, Leon, Aragon and Sicily" Ferdinand and Isabella reigned over their respective territories, although they also took decisions together. Its central position, larger territorial area (three times greater than that of Aragon) and larger population (4.3million as opposed to the 1 million in Aragon) led to Castile becoming the dominating partner in the union.
As a result of the Reconquest the Castilian aristocracy had become very powerful. The monarchs needed to assert their authority over the nobility and the clergy. With this end in mind they founded a law enforcement body, the Consejo de la Hermandad, more commonly known as the Santa Hermandad (the Holy Brotherhood), which was staffed and funded by the municipalities. They also took further measures against the nobility, destroying feudal castles, prohibiting private wars and reducing the power of the adelantados (a governor-like military office in areas recently conquered). The monarchy incorporated military orders under the Consejo de las Órdenes in 1495, reinforced royal judicial power over the feudal one and transformed the Audiencias into the supreme judicial bodies. The crown also sought to better control the cities, and so in 1480 in the Cortes of Toledo it created the corregidores, representatives of the crown, which supervised the city councils. In religion, they reformed religious orders and sought unity of the various sections of the church. They pressured Jews to convert to Catholicism, in some cases persecuted by the Inquisition. Finally in 1492 the monarchs decided that those who would not convert would be expelled. It is estimated that between 50,000 and 70,000 people were expelled from Castile. From 1502 onwards they began to convert the Muslim population.
Between 1478 and 1497 the monarchs conquered the Canary Islands of Gran Canaria, La Palma and Tenerife. On the 2nd January 1492 the monarchs entered Granada's Alhambra marking the end of the Reconquest. Also in 1492 Christopher Columbus discovered the West Indies and in 1497 Castile conquered Melilla. After Castile's conquest of the Kingdom of Granada, its politics turned towards the Mediterranean, and Castile militarily helped Aragon in its problems with France, culminating in the reconquest of Naples for the Crown of Aragon in 1504. Later that same year, Isabella died.
Isabella had excluded her husband from Castile's line of succession, which passed to their daughter Joanna (married to Philip of Austria, nicknamed the Handsome). But Isabella knew of her daughter's illness (for which she was known as Joanna the Mad) and named Ferdinand as regent in the case that Joanna didn't want to or couldn't fulfil her duties. In the Salamanca Agreement of 1505 it was decided that the government would be shared by Phillip, Ferdinand and Joanna. However, poor relations between Phillip (supported by the Castilian nobility) and Ferdinand resulted in Ferdinand renouncing his powers in Castile in order to avoid an armed conflict. Through the Concordia de Villafáfila (1506), Ferdinand returned to Aragon and Phillip was crowned king of Castile. In 1507 Phillip died and Ferdinand returned once again to be regent.
Charles I received the Crown of Castile, Aragon and the Empire through a combination of dynastic marriages and premature deaths:
Charles I was not well-received in Castile. Part of this was because he was a foreign-born King (born in Ghent), and even before his arrival in Castile he had granted important positions to Flemish citizens and had used Castilian money to fund his court. The Castilian nobility and the cities were on the verge of an uprising to defend their rights. Many Castilians favoured the King's younger brother Ferdinand, who grew up in Castile, and in fact the Council of Castile opposed the idea of Charles as King of Castile.
In 1518 the Castilian parliament in Valladolid named a Waloon (Jean de Sauvage) as its president. This caused angry protests in the parliament, which rejected the presence of foreigners in its deliberations. Despite threats, the parliament (lead by Juan de Zumel, representative of Burgos) resisted and forced the King to respect the laws of Castile, remove all foreigners from important governmental posts, and learn to speak Castilian. After taking his oath Charles received a subsidy of 600,000 ducats.
Charles was conscious of the fact that he had many options to be emperor and needed to impose his authority over Castile in order to gain access to its riches for his imperial dream. Castile was one of the more dynamic, rich and advanced territories in Europe in the 16th century and started to realise that it could become immersed within an empire. This, added to the broken promise of Charles, only increased hostility towards the King. In 1520 in Toledo Parliament rejected a further subsidy for the King. Parliament in Santiago de Compostela reached the same decision. Finally, when Parliament was held in La Coruña, many members were bribed and others denied entry, with the result that the subsidy was approved. Those members who voted in favour were attacked by the Castilian people and their houses were burned. Parliament was not the only opposition which Charles would come up against. When he left Castile in 1520 the Castilian War of the Communities broke out. Los comuneros were defeated one year later (1521). After their defeat, Parliament was reduced to a mere consultative body.
Philip II continued the politics of Charles I, but unlike his father he made Castile the centre of his empire, centralising all administration in Madrid. The other states within the peninsula maintained their autonomy, being governed by a Viceroy.
Since the reign of Charles I the financial burden of the empire had fallen mainly on Castile. Under Philip II the cost quadrupled. During his reign, as well as increasing existing taxes he created some new ones, among them the excusado in 1567. That same year Philip ordered the proclamation of the La Pragmática; an act whereby all Moriscos had to abandon all Moorish traditions and become true Catholics. This edict limited religious, linguistic and cultural freedom of the Morisco population and provoked the Morisco Revolt (1568-1571), which was put down by John of Austria.
Castile entered a phase of recession in 1575, which provoked the suspension of wages (the third of his reign). In 1590 the Cortes approved the millones; a new tax on food. This ruined Castilian cities and eliminated their weak attempts at industrialisation. In 1596 pay was once again suspended.
In the previous kingdoms positions in national institutions were filled by educated gentlemen. Philip II's administrators would normally come from either the University of Alcalá or the University of Salamanca. After Philip III the nobility once again asserted their right to govern the country. In order to show that there was a new order ruling there was a cleansing of the blood of Spain. Religious persecution lead Philip to declare the expulsion of the Moriscos in 1609.
Faced with the collapse of the Exchequer, in order to maintain the hegemony of Philip IV's Spanish Empire, the Count-Duke of Olivares, the king's favourite (valido) from 1621 to 1643, tried to introduce a series of reforms. Among these was the Unión de Armas, the creation of a new army of 140,000 reservists. Every territory within the kingdom contributed citizens proportionally in order to maintain the force. His aims of union did not work and the Spanish Crown continued as a confederation of kingdoms.
Luis Méndez de Haro took over from Olivares as favourite Philip IV between 1659 and 1665. This was in order to alleviate interior conflicts sparked off by his predecessor (revolts in Portugal, Catalonia and Andalusia) and achieve peace in Europe.
Upon the death of Philip IV in 1665, and with the incapacity of Charles II to govern, Spain suffered an economic slowdown and battles for power between the different 'favourites'. The death of Charles II in 1700 without descendants provoked the War of the Spanish Succession.
