"Philip the Handsome[a] (22 July 1478 – 25 September 1506), also called the Fair, was Duke of Burgundy from 1482 to 1506 and the first member ...
of the house of Habsburg to be King of Castile.
The son of Holy Roman Emperor Maximilian I 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, as part of an agreement between their fathers. Within four years after the wedding, Joanna became heir presumptive to Aragon and Castile, following the deaths of her brother, elder sister and infant nephew during that period. In 1504, aged 26, Philip became king jure uxoris when his mother-in-law died and Joanna succeeded her. He died only two years later, leaving his wife distraught with grief." - (en.wikipedia.org 08.10.2020)
