Charles Habsburg was born in Ghent, a region now located in Belgium. His four grandparents,
Emperor Maximilian I of the Holy Roman Empire, Duchess Mary of Burgundy, King Ferdinand II
of Aragon, and Queen Isabella I of Castile, carefully planned a dynastic marriage that would
result in one extremely profitable heir. Charles was the eldest son of Philip the Handsome
and Joanna of Castile, and he therefore inherited ample land throughout Europe. From Duchess
Mary of Burgundy, his maternal grandmother, he acquired the remaining land of the Duchy of
Burgundy in southern Europe, Flanders in the north (presently known as Belgium and the
Netherlands), and some holdings in central Europe.
King Ferdinand II of Aragon, his maternal grandfather, left him most of the Iberian Peninsula,
therefore making him King Carlos I of Spain. Charles also inherited eastern Spain and Aragon’s
colonies in the Mediterranean. From Queen Isabella I of Castile, his paternal grandmother,
Charles acquired central Spain and Castile’s American colonies. Emperor Maximilian I of the
Holy Roman Empire, his paternal grandfather, left him the Austrian crownlands.
