Philip the Handsome, also called the Fair, was ruler of the Burgundian Netherlands and titular Duke of Burgundy from 1482 to 1506 and the first Habsburg King of Castile for a brief time in 1506.
The son of Maximilian I, Holy Roman Emperor and Mary of Burgundy, Philip was less than four years old when his mother died, and upon her death, he inherited the Burgundian Netherlands. In 1496, his father arranged for him to marry Joanna, the second daughter of Queen Isabella I of Castile and King Ferdinand II of Aragon. Around the same time, Philip's sister Margaret was given in marriage to Joanna's brother John, Prince of Asturias, as part of an agreement between their fathers. After the deaths of her elder siblings John and Isabella and her infant nephew, Miguel da Paz, Prince of Portugal, Joanna became heir presumptive to the thrones of Castile and Aragon. She became Queen of Castile when her mother died in 1504. Philip was proclaimed King in 1506, but died a few months later, leaving his wife distraught with grief, eventually leading to her father and son Charles seizing power from Joanna and leaving her imprisoned for the rest of her life on account of her alleged insanity.
