A younger son of House of Capet king Louis VIII of France "the Lion", Charles was first given a noble title by his brother Louis IX of France who succeeded to the French throne in 1226. Charles was named Count of Anjou and Maine; the feudal County of Anjou was a western vassal state of the Kingdom of France, which the Capetians had wrested from the House of Plantagenet only a few decades earlier. Charles married the heiress of the County of Provence named Beatrice of Provence, she was a member of the House of Barcelona; this meant Charles' holdings were growing as Count of Provence. After fighting in the Seventh Crusade, Charles was offered by Pope Clement IV the Kingdom of Sicily — which at the time included not only the island of Sicily but also the southern half of the Italian Peninsula. The reason for Charles being offered the kingdom was because of a conflict between the Papacy and the Holy Roman Empire, the latter of whom were represented by the ruling House of Hohenstaufen.
