The Children of Adam and Eve

He was born in 1425 and 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, Princess of Asturias, and became heir apparent to the Castilian throne.

In 1440, at the age of fifteen, he was married to Blanche II of Navarre but the marriage was never consummated. In 1453, after thirteen years, Henry sought a divorce. An official examination confirmed the virginity of Blanche, and a priestquestioned 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, Joan, nicknamed "La Beltraneja". Six years after the birth of the throne's heir, part of the nobility ofCastile 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. This hypothesis was reinforced when the Queen had another twochildren with the nephew of a Bishop. Though many contemporary historians and chroniclers assumed Henry was impotent, the royal chronicles of his reign were all written or revised during the reign and under the influence of Isabella, whosestrong interest in proving Joan illegitimate renders these accounts at least partially suspect. The question of Joan's paternity is therefore not firmly answerable, given the lack of available reliable sources. The doubt of her legitimacy as anheir, 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'snephew. After a long period of conflict between the rival factions, Henry finally agreed to name Isabella his successor, in Guisando (Avila), provided she allow him to arrange her strategic marriage. Isabella would go on to break thisstipulation of the agreement. In 1474 Henry was entombed at Santa María de Guadalupe, next to his mother.

After the death of the king war started in Castile. Joanna was supported by Portugal, while the eventual winner, his half-sister Isabella I of Castile had the support of Aragon via her husband Ferdinand and, later in the war, France.
