Baudouin I was King of the Belgians from 1951 until his death in 1993. He was the last Belgian king to be sovereign of the Congo.
Baudouin was the elder son of King Leopold III (1901–1983) and his first wife, Princess Astrid of Sweden (1905–1935). Because he and his wife, Queen Fabiola, had no children, at Baudouin's death the crown passed to his younger brother, King Albert II.
