Philip the Handsome was born in Bruges, Flanders, Burgundian Netherlands on 22 July 1478, the son of Emperor Maximilian I of Germany and Duchess Mary of Burgundy. Philip belonged to the House of Habsburg, and he succeeded his mother as Lord of the Netherlands and Duke of Burgundy upon her death in 1482, becoming the first ruler of the Habsburg Netherlands. His early reign saw the Flemish people revolt against his father's rule, but the rebellions ended in 1494 when Philip came of age to become the new prince. Philip was assisted by a council of Burgundian notables, and he was later married to Joanna of Castile, the daughter of King Ferdinand II of Aragon and Isabella of Castile. The alliance led to the House of Habsburg and House of Trastamara forming a powerful military alliance that could check the power of France, and it would also lead to Philip becoming the jure uxoris King of Castile when Queen Isabella died in 1504. Philip and his wife were forced to fight against Ferdinand II when he sought to become "regent", and Philip and Joanna landed in Coruna with German mercenaries in 1506, leading to mediation between Ferdinand and Philip. Under the 27 June 1506 Treaty of Villafafila, Philip was confirmed as the new King of Castile, but he died of typhoid fever on 15 September 1506. His wife believed that he had been poisoned, a widely suspected cause of death. While Philip's reign was short, the Habsburg inheritance of Burgundian territories would lead to several conflicts with France and, eventually, the independence of the Netherlands.
