Peter II of Courtenay

Peter II of Courtenay (c. 1155–c. 1218), son of Peter I of Courtenay and cousin of King Philip II of France, took the cross on the Third Crusade in 1190 and later fought in the Albigensian Crusade and at Bouvines. Chosen Latin emperor after his brother-in-law Henry of Flanders died in 1216, he was crowned in Rome by Pope Honorius III in April 1217.

He borrowed Venetian ships, promising to capture Durazzo, but failed and continued overland. Theodore Komnenos Doukas of Epirus captured him, and Peter died in captivity without ruling Constantinople, where his wife Yolanda governed for a time.
