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.
