The Capetian House of Anjou was a royal house and cadet branch of the direct French House of Capet, part of the Capetian dynasty. It is one of three separate royal houses referred to as "Angevin", meaning "from Anjou" in France. Founded by Charles I of Anjou, the youngest son of Louis VIII of France, the Capetian king first ruled the Kingdom of Sicily during the 13th century. Later the War of the Sicilian Vespers forced him out of the island of Sicily, leaving him with the southern half of the Italian Peninsula — the Kingdom of Naples. The house and its various branches would go on to influence much of the history of Southern and Central Europe during the Middle Ages, until becoming defunct in 1435.
