Historical Trajectory
Phase I: Rise
The Kingdom of Naples emerged from the War of the Sicilian Vespers (1282–1302), after a revolt drove the Angevins from the island of Sicily, leaving Charles of Anjou ruling the southern Italian mainland under the continued title 'Kingdom of Sicily.' The Angevin dynasty consolidated control over this strategically vital region south of the Papal States, establishing Naples as a major Mediterranean political center.
Phase II: Zenith
Under Aragonese rule following Alfonso V's unification of Naples into his dominions in 1442, the kingdom became a culturally significant hub of the Italian Renaissance. Spanish control from 1504 made Naples one of the wealthiest and most populous cities in Europe, serving as an essential source of revenue and military manpower for the Spanish Crown throughout the 16th and 17th centuries.
Phase III: Decline
The War of the Spanish Succession transferred Naples to the Austrian Habsburgs via the 1714 Treaty of Rastatt. Spanish Bourbon forces recaptured it in 1734, installing Charles, Duke of Parma, as king. This Bourbon line persisted until 1816, when the kingdom was formally merged with the island of Sicily to create the Kingdom of the Two Sicilies, ending Naples's existence as a separate state.
