The Kingdom of Naples (, ), comprising the southern part of the Italian Peninsula, was the remainder of the old Kingdom of Sicily after the secession of the island of Sicily as a result of the Vespers of 1282. It continued to be officially known as the Kingdom of Sicily, although it no longer included the island of Sicily. For much of its existence, the realm was contested between French and Spanish dynasties. In 1816, it was reunified with the island kingdom of Sicily once again to form the Kingdom of the Two Sicilies.
