Charles of Anjou defeated and killed King Manfred at the Battle of Benevento, opening the way for Angevin rule in southern Italy. The victory reflected papal efforts to replace the Hohenstaufen dynasty with a more dependable ally. This shift set up decades of conflict over who would control the former Kingdom of Sicily (the mainland south and the island).
Charles of Anjou defeated Conradin at the Battle of Tagliacozzo, the last major military attempt by the Hohenstaufen line to regain the throne. The battle ended organized Hohenstaufen resistance in Italy and strengthened Angevin control of the mainland kingdom. It also made the succession question in the south primarily a contest among new rivals, not a restoration of the old dynasty.
After being captured, Conradin was executed in Naples. The execution removed a symbolic rival claimant and helped the Angevins consolidate rule through deterrence and force. It also deepened political divisions, contributing to long-term instability in the region.
A revolt in Palermo at the time of evening prayers (vespers) triggered widespread violence against the Angevin French and rapidly spread across Sicily. The uprising started a prolonged struggle between Angevin and Aragonese forces over the old kingdom. From this point, mainland Naples and the island of Sicily followed increasingly separate political paths.
A diplomatic settlement at Anagni involved the papacy, France, Naples, and Aragon, aiming to end conflict over Sicily. However, the Sicilians and Frederick (James II’s brother) rejected the agreement, and fighting continued. The treaty shows how international the Naples–Sicily question had become, tying southern Italy to wider Mediterranean politics.
The Peace of Caltabellotta ended the War of the Sicilian Vespers by confirming a divided settlement. Insular Sicily went to Frederick III (as the Kingdom of Trinacria), while the mainland realm remained under Angevin rule (commonly called the Kingdom of Naples by modern historians). This division shaped southern Italian politics for the next two centuries.
Andrew, Duke of Calabria and husband of Queen Joanna I, was killed at Aversa, and suspicion fell on factions within the Neapolitan court. The death gave Joanna’s Hungarian relatives a strong motive to intervene, turning a dynastic dispute into open international conflict. It also weakened confidence in Joanna’s rule at a critical moment.
Facing political danger, Joanna I negotiated with the papacy in Avignon and sold the city to Pope Clement VI. The sale helped secure papal support at a moment when Joanna’s legitimacy was contested. It also tied Neapolitan politics to papal finances and diplomacy in a very direct way.
Hungarian forces defeated Neapolitan troops at Capua during Louis I of Hungary’s campaign to punish those blamed for Andrew’s death. The victory helped Hungary occupy key parts of the kingdom and intensified internal divisions among Neapolitan nobles. The episode showed how fragile Angevin authority in Naples could be under external pressure.
Under pressure from Angevin rivals and local unrest, Queen Joanna II adopted Alfonso V of Aragon as her heir. Alfonso arrived and began intervening in Neapolitan government, showing that adoption could function as a political tool in succession disputes. The move opened the door for Aragon to reassert a direct claim in Naples, not just in Sicily.
After years of war against René of Anjou and other claimants, Alfonso V secured control of Naples in 1442. His victory marked the decisive shift from the Angevin line to Aragonese rule in the mainland kingdom. Naples became closely connected to the wider Aragonese (later Spanish) political system in the western Mediterranean.
Charles VIII of France entered Naples during a rapid campaign based on French claims linked to the Angevin legacy. Although the occupation was short-lived, it showed how vulnerable the kingdom was to major foreign armies and how succession claims could be used to justify invasion. This accelerated the broader Italian Wars and kept Naples at the center of great-power rivalry.
France and Aragon secretly agreed to divide the Kingdom of Naples, sidelining its existing ruler and institutions. The plan quickly produced disputes over territory and revenue, helping trigger renewed fighting. The treaty illustrates how Naples had become an object of negotiation between outside powers rather than a fully independent actor.
At Cerignola, Gonzalo Fernández de Córdoba led Spanish forces to a major victory over the French. The battle was notable for effective use of field fortifications and firearms, helping Spain gain momentum in the struggle for Naples. It weakened French control in the south and set up the final push to remove them from the kingdom.
Spanish forces defeated the French at the Garigliano River near Gaeta, forcing a major French retreat. The victory completed Spain’s military advantage and effectively ended the contest for direct rule in Naples during this phase of the Italian Wars. By the end of 1503, the Angevin–Aragonese succession struggle had transitioned into a clearer Spanish-dominated outcome.
