(Former Queen of Castile (1504 - 1555))
Birthdate: November 6, 1479
Sun Sign: Scorpio

Joanna of Castile ruled as queen of Castile and Aragon. Despite being the ruling queen, her impact on national policy was limited due to being declared insane and confined to the Royal Convent of Santa Clara in Tordesillas. Her husband, Philip I, became king of Castile in 1506. After her father's death in 1516, she inherited his kingdom as well. Her son Charles I succeeded her and became the sole ruler of Castile and Aragon upon her death in 1555.
