Charles V inherited a vast empire that stretched from one end of Europe to the other. He acquired the Spanish throne from his parents, Philip I and Queen Joan, and his maternal grandparents and Burgundy through his father’s mother—who had been the duchess of Burgundy. His claim to the Habsburg throne came from his father’s father, Maximilian I. Maximilian had also been the Holy Roman emperor, a seat to which one was elected. Charles V won the electoral votes necessary to secure his own claim to the empire by, among other things, touting his descent from Maximilian.
