Royal Court of Naples and Sicily
The Kingdom of Naples (Italian: Regno di Napoli), comprising the southern part of the Italian Peninsula, was the remainder of the old Kingdom of Sicily after secession of the island of Sicily as a result of the Sicilian Vespers rebellion of 1282. Known to contemporaries as the Kingdom of Sicily as it was the de jure remnant of that kingdom, it is dubbed Kingdom of Naples to distinguish it from the island-based polity. During much of its existence, the realm was contested between French and Aragonese (Spanish) dynasties. In 1816, it again merged with the island-based Kingdom of Sicily to form the Kingdom of the Two Sicilies.
