Joan of Portugal

Here is the revised memorial biography of Joan of Portugal, refined and carefully grounded in well-documented historical sources:

Joan of Portugal (Portuguese: Joana [ʒuˈɐnɐ]; born 31 March 1439 – died 13 June 1475) was Queen consort of Castile as the second wife of King Henry IV of Castile. She was the posthumous daughter of King Edward (Duarte) of Portugal and Eleanor of Aragon, born at the Quinta do Monte Olivete in Almada, six months after her father's death (en.wikipedia.org).

Born into the House of Aviz, Joan was one of nine children. After her mother's ousting from the regency and subsequent exile to Castile, young Joan lived at the monastery of Santa María de Medina del Campo. Following Eleanor’s death in February 1445, Joan returned to Portugal under the guardianship of her uncle Peter and was raised at the Lisbon court (en.wikipedia.org).

On 21 May 1455, Joan married King Henry IV of Castile in Córdoba. The marriage was controversial—rumors suggest it may never have been consummated, possibly due to the king’s alleged impotence (en.wikipedia.org). Six years later, in February 1462, she gave birth to a daughter, also named Joanna, later dubbed "La Beltraneja" amid persistent rumors that the child's father was actually Beltrán de la Cueva, a powerful court favorite (en.wikipedia.org).

Joan's later life was marked by scandal. She was banished from court and took up residence at Coca Castle with Bishop Fonseca, where she engaged in an affair with his nephew. This liaison resulted in two illegitimate sons, Pedro Apostol de Castilla y Portugal and Andrés Apostol de Castilla y Portugal, further tarnishing her reputation. In 1468, Henry declared their marriage invalid and annulled it (en.wikipedia.org).

After Henry’s death in December 1474, Joan fervently defended her daughter’s right to the Castilian throne. However, she died on 13 June 1475 in Madrid, mere months after her husband, and was buried at the convent of San Francisco in Madrid (en.wikipedia.org).
