Charles I of Anjou (1226/1227–1285) was the youngest son of Louis VIII of France. He acquired vast territories and many titles by a variety of means and founded the Second House of Anjou. He accompanied Louis during the Seventh Crusade to Egypt. In 1263 he agreed with the Holy See to seize the Kingdom of Sicily, which included southern Italy to well north of Naples. Pope Urban IV declared a crusade against the incumbent Manfred, and Charles occupied the kingdom with little resistance. In 1270 he took part in the Eighth Crusade and forced the caliph of Tunis to pay him a yearly tribute. The popes tried to channel his ambitions away from Italy and assisted him in acquiring claims to Achaea and Jerusalem. In 1281 Charles was authorised to launch a crusade against the Byzantine Empire. A riot, known as the Sicilian Vespers, broke out in March 1282 that put an end to his rule on the island of Sicily. He was able to defend the mainland territories with the support of France and the Holy See.
