Joanna la Beltraneja

Born in 1462, Joanna was the daughter of King Henry IV of Castile and his wife Joan of Portugal. Joanna's legitimacy was questioned, leading to a longstanding dispute over the Castilian throne. Following her father's death, she became a rival claimant to the throne against her half-sister Isabella I of Castile. In 1475, Joanna's supporters called for her recognition as queen, but the Castilian Civil War ensued. The conflict ended with Isabella's ascension, and Joanna remained in a position of political marginalization. She lived much of her life in a state of exile and ultimately passed away in 1530, with her claim to the throne largely forgotten.
