Otto IV of Burgundy
Otto IV of Burgundy (c. 1248–1303), son of Hugh of Chalon and Countess Adelaide I, became Count of Chalon in 1267 and inherited the County of Burgundy in 1279, though he made good his authority only in 1295.
Otto married Philippa of Bar in 1271 and Mahaut of Artois in 1285. His daughters Joan II and Blanche both married kings of France. He died at Melun on 17 March 1303, and Joan II succeeded him; the county later passed as her dowry on her marriage to Philip, the future king of France.
