Neapolitan lira (1812–15)
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 dynasties. In 1816, it again merged with the island-based Kingdom of Sicily to form the Kingdom of the Two Sicilies.
Angevin Kingdom of Naples 
Following the rebellion, King Charles I of Sicily (Charles of Anjou) was forced to leave the island of Sicily by Peter III of Aragon's troops. Charles, however, maintained his possessions on the mainland, customarily known as the "Kingdom of Naples", after its capital city. Charles and his Angevin successors maintained a claim to Sicily, warring against the Aragonese until 1373, when Queen Joan I of Naples formally renounced the claim. Joan's reign was contested by Louis the Great, the Angevin King of Hungary, who captured the kingdom several times (1348–1352).
Queen Joan I also played a part in the ultimate demise of the first Kingdom of Naples. As she was childless, she adopted Louis I, Duke of Anjou as her heir, in spite of the claims of her cousin, the Prince of Durazzo, effectively setting up a junior Angevin line in competition with the senior line. This led to Joan I's murder at the hands of the Prince of Durazzo in 1382, and his seizing the throne as Charles III of Naples. The two competing Angevin lines contested each other for the possession of the Kingdom of Naples over the following decades. Charles III's daughter Joan II (r. 1414-1435) adopted Alfonso V of Aragon (whom she later repudiated) and Louis III of Anjou as heirs alternately, finally settling succession on Louis' brother René of Anjou of the junior Angevin line, and he succeeded her in 1435.
René of Anjou temporarily united the claims of junior and senior Angevin lines. In 1442, however, Alfonso V conquered the Kingdom of Naples and unified Sicily and Naples once again as dependencies of Aragon. At his death in 1458, the kingdom was again separated and Naples was inherited by Ferrante, Alfonso's illegitimate son.
Aragonese and Spanish Kingdom of Naples 
When Ferrante died in 1494, Charles VIII of France invaded Italy, using the Angevin claim to the throne of Naples, which his father had inherited on the death of King René's nephew in 1481, as a pretext, thus beginning the Italian Wars. Charles VIII expelled Alfonso II of Naples from Naples in 1495, but was soon forced to withdraw due to the support of Ferdinand II of Aragon for his cousin, Alfonso II's son Ferrantino. Ferrantino was restored to the throne, but died in 1496, and was succeeded by his uncle, Frederick IV. The French, however, did not give up their claim, and in 1501 agreed to a partition of the kingdom with Ferdinand of Aragon, who abandoned his cousin King Frederick. The deal soon fell through, however, and Aragon and France resumed their war over the kingdom, ultimately resulting in an Aragonese victory leaving Ferdinand in control of the kingdom by 1504.
The Spanish troops that were occupying Calabria and Apulia, led by Gonzalo Fernandez de Cordova and public inspectors to Fernando the Catholic, did not respect the new agreements and Frenchmen were expelled from Mezzogiorno. The agreements of peace that continued were never definitive, but they established at least for that the title of King of Naples was waiting to Carlos I of Spain and his future wife Claudia. Fernando the Catholic nevertheless continued to possessing the kingdom being considered to be a legitimate inheritor of his uncle Alfonso I of Naples and of the former one Kingdom of Sicily (Regnum Utriusque Siciliae)
The kingdom continued to be a focus of dispute between France and Spain for the next several decades, but French efforts to gain control of it became feebler as the decades went on, and Spanish control was never genuinely endangered. The French finally abandoned their claims to the kingdom by the Treaty of Cateau-Cambrésis in 1559. With the Treaty of London (1557) the new territory of "Stato dei Presidi" (State of Presidi) was born and was governed directly by Spain, as part of the Kingdom of Naples.
Austrian Habsburg and Spanish Bourbon Kingdom of Naples 
After the War of the Spanish Succession in the early 18th century, possession of the kingdom again changed hands. Under the terms of the Treaty of Rastatt in 1714, Naples was given to Charles VI, the Holy Roman Emperor. He also gained control of Sicily in 1720, but Austrian rule did not last long. Both Naples and Sicily were conquered by a Spanish army during the War of the Polish Succession in 1734, and Charles, Duke of Parma, a younger son of King Philip V of Spain was installed as King of Naples and Sicily from 1735. When Charles inherited the Spanish throne from his older half-brother in 1759, he left Naples and Sicily to his younger son, Ferdinand IV. Despite the two Kingdoms being in a personal union under the Austrian and Spanish dynasts, they remained constitutionally separate.
Being a member of the House of Bourbon, Ferdinand IV was a natural opponent of the French Revolution and Napoleon. In 1798, he briefly occupied Rome, but was expelled from it by French Revolutionary forces within the year. Soon afterwards Ferdinand fled to Sicily. In January 1799 the French armies installed a Parthenopaean Republic, but this proved short-lived, and a peasant counter-revolution inspired by the clergy allowed Ferdinand to return to his capital. However in 1801 Ferdinand was compelled to make important concessions to the French by the Treaty of Florence, which reinforced France's position as the dominant power in mainland Italy.
Napoleonic Kingdom of Naples 
Ferdinand's decision to ally with the Third Coalition against Napoleon in 1805 proved more damaging. In 1806, following decisive victories over the allied armies at Austerlitz and over the Neapolitans at Campo Tenese, Napoleon installed his brother, Joseph as King of Naples. When Joseph was sent off to Spain two years later, he was replaced by Napoleon's sister Caroline and his brother-in-law Marshal Joachim Murat, as King of the Two Sicilies.
Meanwhile, Ferdinand had fled to Sicily, where he retained his throne, despite successive attempts by Murat to invade the island. The British would defend Sicily for the remainder of the war but despite the Kingdom of Sicily nominally being part of the Fourth, Fifth and Sixth Coalitions against Napoleon, Ferdinand and the British were unable to ever challenge French control of the Italian mainland.
After Napoleon's defeat in 1814, Murat reached an agreement with Austria and was allowed to retain the throne of Naples, despite the lobbying efforts of Ferdinand and his supporters. However, with most of the other powers, particularly Britain, hostile towards him and dependent on the uncertain support of Austria, Murat's position became less and less secure. Therefore when Napoleon returned to France for the Hundred Days in 1815, Murat once again sided with him. Realising the Austrians would soon attempt to remove him, Murat gave the Rimini Proclamation in a hope to save his kingdom by allying himself with Italian nationalists. The ensuing Neapolitan War between Murat and the Austrians was short, ending with a decisive victory for the Austrian forces at the Battle of Tolentino. Murat was forced to flee, and Ferdinand IV of Sicily was restored to the throne of Naples. Murat would attempt to regain his throne but was quickly captured and executed by firing squad in Pizzo, Calabria. The next year, 1816, finally saw the formal union of the Kingdom of Naples with the Kingdom of Sicily into the new Kingdom of the Two Sicilies.
