Philip I of Castile

Philip I known as Philip the Handsome or the Fair, was the first member of the house of Habsburg to be King of Castile. The son of Holy Roman Emperor Maximilian I, at the age of three Philip inherited the greater part of the Duchy of Burgundy and the Burgundian Netherlands from his mother, Mary, and atbriefly succeeded to the Crown of Castile as the husband of Queen Joanna, who was also heiresspresumptive to the Crown of Aragon. He was the first Habsburg monarch in Spain. He never inherited his fathers territories or became Holy Roman Emperor because he predeceased his father, but his son Emperor Charles V eventually united the Habsburg, Burgundian, Castilian, and Aragonese inheritances.

Philip was born in Bruges to Mary of Burgundy and Maximilian I, Holy Roman Emperor, during the reign of his grandfather Frederick III in the County of Flanders and was named after his greatgrandfather, Philip the Good, grandfather of his mother Mary. In 1482, upon the death of his mother, he succeeded to her Burgundian possessions under the guardianship of his father. A period of turmoil ensued which witnessed sporadic hostilities between, principally, the large towns of Flanders and the supporters of Maximilian.
