Charles, Duke of Burgundy (born 1433)

Charles Martin, called the Bold, was the last duke of Burgundy from the House of Valois-Burgundy, ruling from 1467 to 1477. He was the only surviving legitimate son of Philip the Good and his third wife, Isabella of Portugal. As heir and as ruler, Charles vied for power and influence with rivals such as his overlord, King Louis XI of France. In 1465, Charles led a successful revolt of Louis's vassals in the War of the Public Weal.
