Queen
Isabella's father was the regent for her cousin Afonso V during his minority. Reportedly, Isabella and Afonso fell in love with each other. They were engaged in 1445, which caused a conflict between Peter of Coimbra and Duke Afonso of Braganza, who had wished for the monarch to marry his grandchild.
