Joan of Portugal - Queen of Castile

Queen of Castile

On 21 May 1455 in Córdoba, Spain, she married as his second wife King Henry IV of Castile who had repudiated his first consort, Blanche II of Navarre, after thirteen years of marriage. It was rumoured that their marriage had never been consummated due to the king's impotence. In February 1462, six years after Joan's marriage to Henry, she gave birth to a daughter, also named Joan, called La Beltraneja because of rumours that she was in fact the daughter of Don Beltrán de la Cueva, 1st Duke of Alburquerque, who was suspected of being Joan's lover.

Henry banished Joan from the royal court and she went to live in Coca at the castle of Henry's supporter, Bishop Fonseca. She soon fell in love with Bishop Fonseca's nephew; they embarked on a sexual affair, which resulted in Joan bearing her lover two illegitimate sons (see below). Henry subsequently declared their marriage had never been legal and thus divorced her in 1468.

At the death of her former husband in 1474, Joan championed her daughter's right to succeed to the throne, but she died shortly thereafter.
