The Kings and Queens of Naples are usually dated from its forced union with the Norman Kingdom of Sicily in 1137. Prior to this it was merely one of several duchies on the lower Italian peninsula.

James IV's desperate attempts to hold onto Naples led him to promise the throne and his daughter's hand to various local powers. Added to this a web of marriages has extended claims. On Isabella's death the kingdom is claimed by Sicily, Aragon, Luxembourgois Hungary, France and Auvergne. Austria would also wade into this while the Papacy used the shifting alliances to its own ends. Eventually France secures the succession and places the Duke of Alençon and his Luxembourg wife on throne to rule jointly.
