"Charles I (early 1226/1227 – 7 January 1285), commonly called Charles of Anjou, was a member of the royal Capetian dynasty and the founder of the second House of Anjou. He was Count of Provence (1246–85) and Forcalquier (1246–48, 1256–85) in the Holy Roman Empire, Count of Anjou and Maine (1246–85) in France; he was also King of Sicily (1266–85) and Prince of Achaea (1278–85). In 1272, he was proclaimed King of Albania; and in 1277 he purchased a claim to the Kingdom of Jerusalem.
The youngest son of Louis VIII of France and Blanche of Castile, Charles was destined for a Church career until the early 1240s. He acquired Provence and Forcalquier through his marriage to their heiress, Beatrice. His attempts to secure comital rights brought him into conflict with his mother-in-law, Beatrice of Savoy, and the nobility. He received Anjou and Maine from his brother, Louis IX of France, in appanage. He accompanied Louis during the Seventh Crusade to Egypt. Shortly after he returned to Provence in 1250, Charles forced three wealthy free imperial cities—Marseilles, Arles and Avignon—to acknowledge his suzerainty." - (en.wikipedia.org 31.01.2020)
