Philip I of Taranto, of the Angevin house, was titular Latin Emperor of Constantinople by right of his wife Catherine of Valois–Courtenay, Despot of Romania, King of Albania, Prince of Achaea and Taranto.

The Capetian House of Anjou, or House of Anjou-Sicily, or House of Anjou-Naples was a royal house and cadet branch 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. The War of the Sicilian Vespers later forced him out of the island of Sicily, which left 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 it became extinct in 1435.
