Кастилия және Леон королі Энрике IV

King of Castile and León from 1454 to 1474

Henry IV of Castile (Castilian: Enrique IV; 5 January 1425 – 11 December 1474), nicknamed the Impotent, was King of Castile and León and the last of the weak late medieval kings of Castile and León. During Henry's reign, the nobles became more powerful and the nation became less centralised.

Henry was born in 1425 at the Casa de las Aldabas (since destroyed) in Teresa Gil street of Valladolid. He was the son of John II of Castile and Maria of Aragon, daughter of King Ferdinand I of Aragon. He displaced his older sister, Eleanor, and became heir apparent to the Castilian throne as the Prince of Asturias. At the time of his birth, Castile was under control of Álvaro de Luna, Duke of Trujillo, who intended to select Henry's companions and direct his education. The companions of his own age included Juan Pacheco, who became his closest confidant. The struggles, reconciliations and intrigues for power among the aristocracy, Álvaro de Luna, and the Infantes of Aragon would be constant. On 10 October 1444, he became the first and only prince of Jaén. In 1445 he won the First Battle of Olmedo, defeating the Infantes of Aragon. After the victory at Olmedo, Álvaro de Luna's power waned, and Prince Henry and Juan Pacheco's influence grew.

Henry IV's father died on 20 July 1454 and he was proclaimed king the following day. One of King Henry's first priorities was the alliance with Portugal. He achieved this by marrying a second time to Joan of Portugal, daughter of King Edward of Portugal, in 1455; and by meeting her brother King Afonso V of Portugal in Elvas in 1456. His other main concerns were the possibility of intervention from King John II of Navarre, establishing peace with France and Aragon, and pardoning various aristocrats. Henry IV convened the Cuéllar Courts to launch an offensive against the Emirate of Granada. In 1458, King Alfonso V of Aragon died and was succeeded by his brother, John II of Navarre. King John II resumed his interference in Castillian politics, supporting the aristocratic opposition to Juan Pacheco's ambitions. With the support of the King Henry, Pacheco moved to seize Álvaro de Luna's assets, but his widow allied herself with the Mendoza family, causing a division among the aristocracy. This process resulted in the formation of a League of Nobles in March 1460. They raised a large number of noblemen, took control of expenditure, and gained the acceptance of Alfonso of Castile, the King Henry's half brother and Prince of Asturias. To counteract King John II's politicking, Henry IV reacted by invading Navarre in support of Charles, Prince of Viana. Charles was the heir to Navarre, and he revolted against his father John II in 1450 when he refused to cede the throne of Navarre. King John II was in conflict with the Principality of Catalonia, and on the death of his eldest son, Charles of Viana, the principality elected Henry IV to be Count of Barcelona on 11 August 1462. King Henry's intervention was framed as a rivalry between him and John II, making Catalonia an unstable point in the Crown of Aragon. But he was unsuccessful, and the Castillian economy would suffer from an enmity with France, who had supported John II with the Treaty of Bayonne. During his reign as king, Henry IV spent a lot of time at the Royal Alcázar of Madrid where he would stay for long periods of time. The Royal Alcazar was later replaced with the Royal Palace of Madrid by the rulers of Spain.

Prince Henry celebrated his marriage to Blanche of Navarre in 1440, when he was 15 years old. The cardinal Juan de Cervantes presided over the official ceremony. Her parents were Blanche I of Navarre and John II of Navarre. The marriage had been agreed in 1436 as part of the peace negotiations between Castile and Navarre. The dowry included territories and villas that had previously belonged to Navarre but had been won by the Castillian side during the war, and the Castilians agreed to hand the lands back provided they would be given them back again as part of this dowry. This neatly reflected the recent political changes: Castile had supported Charles, Prince of Viana in his fight against John II of Aragon for the Navarrese throne since 1451, and Álvaro de Luna, Duke of Trujillo had been executed in May 1453, leaving Henry with greater control of Castile. One of Henry's detractors, the historian Alfonso de Palencia, wrote that the marriage had been a sham and accused Henry of despising his wife and planning to commit adultery to bear children. According to Palencia, Henry demonstrated "most extreme abhorrence" to his wife, and indifference to the confines of marriage. This arrangement, however, did not last long.

Before the birth of his daughter, Henry convened the Court in Madrid and Joanna was sworn in as Princess of Asturias. But a conflict with the nobility was created when Beltrán de la Cueva deposed Juan Pacheco, the Marquis of Villena, and his brother Pedro Girón, Master of Calatrava from Henry's court. This caused a change in alliances: Mendoza began to support the king, and Pacheco revived the Aristocratic League aimed at eliminating the influence of Beltrán de la Cueva. They had doubts about the paternity of Henry's daughter, saying that she was in fact the daughter of the new favourite, and started referring to her as "la Beltraneja". France initially supported Joanna, yet in 1476, after losing the Battle of Toro, France refused to help Joanna further and in 1478 signed a peace treaty with Isabella.

In 1440, at the age of fifteen, he was married to Blanche II of Navarre. The marriage was never consummated. In 1453, after thirteen years, Henry sought an annulment. An official examination confirmed the virginity of Blanche, and a priest questioned the prostitutes of Segovia, who confirmed that Henry was sexually capable. Blanche was sent home; eight years later, she became de jure Queen of Navarre and died under strange circumstances. In 1455, Henry married Joan of Portugal, sister of Afonso V of Portugal. After six years of marriage, in 1462, she gave birth to a daughter, Joanna, nicknamed "La Beltraneja". Six years after the birth of the throne's heir, part of the nobility of Castile revolted against the king. The rebels claimed that the princess was not the daughter of the king, but actually the daughter of Beltrán de La Cueva, 1st Duke of Alburquerque (thus the nickname "Beltraneja"). This hypothesis was reinforced when the Queen had another two children with the nephew of a bishop. Though many contemporary historians and chroniclers believed Henry was impotent or homosexual, the royal chronicles of his reign were all written or revised during the reign (and under the influence) of Isabella I, his half sister and ultimate successor, whose strong interest in proving Joanna illegitimate renders these accounts at least partially suspect, in addition to the fact that female prostitutes testified to having intercourse with Henry. The question of Joanna's paternity and right to the throne is therefore not firmly answerable, given the lack of available reliable sources. The doubt of her legitimacy as an heir, the weakness of the king, the adultery of the queen, and the unruliness of the nobility all set the stage for a struggle for succession after Henry's death. Henry divorced his wife after her scandalous behavior with Bishop Fonseca's nephew. After a long period of conflict between the rival factions, Henry finally agreed to name Isabella his successor, in Guisando (Ávila), provided she allow him to arrange her strategic marriage. Isabella would go on to break this stipulation of the agreement. Henry died in 1474 and was buried at Santa María de Guadalupe, next to his mother.

Henry was a striking man. Tall, blonde and well built, he had broken his nose as a child. The accident left him with an adult face that made him look, depending on to whom one listened, like either a terrifying lion or a foolish monkey.
