'''Ferdinand I''' ([[Italian language|Italian]]: ''Ferdinando I''; 12 January 1751 – 4 January 1825) was [[Kingdom of the Two Sicilies|King of the Two Sicilies]] from 1816 until his death. Before that he had been, since 1759, [[King of Naples]] as '''Ferdinand IV''' and [[King of Sicily]] as '''Ferdinand III'''. He was deposed twice from the throne of Naples: once by the revolutionary [[Parthenopean Republic]] for six months in 1799, and again by a [[Invasion of Naples (1806)|French invasion]] in 1806, before being restored in 1815 at the end of the [[Napoleonic Wars]].

Ferdinand was born in Naples as the third son of [[Charles III of Spain|King Charles VII]] and [[Maria Amalia of Saxony|Queen Maria Amalia]]. In August 1759, Charles succeeded his half-brother [[Ferdinand VI of Spain]] as King Charles III, but treaty provisions made him ineligible to hold all three crowns. On 6 October, he abdicated his Neapolitan and Sicilian titles in favour of his third son, Ferdinand, because his eldest son [[Infante Philip, Duke of Calabria|Philip]] had been excluded from succession due to intellectual disability and his second son [[Charles IV of Spain|Charles]] was heir-apparent to the Spanish throne. Ferdinand was the founder of the cadet [[House of Bourbon-Two Sicilies]].

==Childhood==
[[Image:Ferdinand IV at age nine.jpg|thumb|left|Ferdinand in 1760, at age nine]]
Ferdinand was born in [[Naples]] and grew up amidst many of the monuments erected there by his father which can be seen today; the Palaces of [[Palace of Portici|Portici]], [[Caserta Palace|Caserta]] and [[Museo di Capodimonte|Capodimonte]].

Ferdinand was his parents' third son; his elder brother [[Charles IV of Spain|Charles]] was expected to inherit Naples and Sicily. When his father ascended the Spanish throne in 1759, he abdicated the thrones of Naples and Sicily in  Ferdinand's favour in accordance with the treaties forbidding the union of the two crowns. A [[Regent|regency]] council presided over by the Tuscan [[Bernardo Tanucci]] was set up. Tanucci, an able, ambitious man, wishing to keep the government as much as possible in his own hands, purposely neglected the young king's education, and encouraged him in his love of pleasure, his idleness and his excessive devotion to [[outdoor sports]].<ref name=Acton>{{cite book|last=Acton|first=Harold|title=The Bourbons of Naples (1731-1825)|year=1957|publisher=Faber and Faber|location=London|edition=2009|isbn=9780571249015|page=150}}</ref><ref name=EB1911/>

==Reign==
Ferdinand's minority/childhood ended in 1767, and his first act was the expulsion of the [[Society of Jesus|Jesuits]]. The following year he married [[Maria Carolina of Austria|Archduchess Maria Carolina]], daughter of [[Maria Theresa|Empress Maria Theresa]]. By the marriage contract, the queen was to have a voice in the council of state after the birth of her first son, and she was not slow to avail herself of this means of political influence.<ref name=EB1911/>

Tanucci, who attempted to thwart her, was dismissed in 1777. The Englishman Sir [[John Francis Edward Acton|John Acton]], who in 1779 was appointed director of marine, won Maria Carolina's favour by supporting her scheme to free Naples from Spanish influence, securing ''rapprochement'' with the [[Archduchy of Austria]] and the [[Kingdom of Great Britain]]. He became practically and afterward actually prime minister. Although not a mere grasping adventurer, he was largely responsible for reducing the internal administration of the country to a system of [[espionage]], [[corruption]] and [[cruelty]].<ref name=EB1911/>

==French occupation and the Parthenopaean Republic==
Although peace was made with France in 1796, the demands of the [[French Directory]], whose troops occupied Rome, alarmed Ferdinand once more. At his wife's instigation, he took advantage of [[Napoleon]]'s absence in the [[French campaign in Egypt and Syria]] and of [[Horatio Nelson]]'s victories to go to war. Ferdinand marched with his army against the French and entered Rome (29 November). On the defeat of some of his columns, Ferdinand hurried back to Naples. On the approach of the French, Ferdinand fled on 23 December 1798 aboard Nelson's ship {{HMS|Vanguard|1787|6}} to [[Palermo]], leaving his capital in a state of anarchy.<ref name=Davis>{{cite book|last=Davis|first=John|title=Naples and Napoleon: Southern Italy and the European Revolutions, 1780-1860|year=2006|publisher=Oxford University Press|isbn=9780198207559|url=https://books.google.com/books?id=yWuH77qlSWEC}}</ref><ref name=EB1911/> The weather was extremely stormy and the king's 6-year-old younger son [[Prince Alberto of Naples and Sicily|Prince Alberto]] died of exhaustion during the voyage, in the arms of [[Emma, Lady Hamilton]], Nelson's mistress.<ref>Oman, Carola, ''Nelson'', 1950 ed., pp.293-4</ref>

The French entered the city despite the fierce resistance of the ''[[lazzaroni (Naples)|lazzaroni]]'', and with the aid of the nobles and bourgeoisie, established the [[Parthenopean Republic]] in January 1799. A few weeks later, when the French troops were recalled to northern Italy, Ferdinand sent a hastily assembled force under [[Fabrizio Ruffo|Fabrizio Cardinal Ruffo]] to reconquer the mainland kingdom. Ruffo, with the support of British artillery, the Church, and the pro-Bourbon aristocracy, succeeded in reaching Naples in May 1799, and the Parthenopean Republic collapsed.<ref name=EB1911/> After some months, King Ferdinand returned to the throne.

The king and the queen were anxious that no mercy should be shown to the rebels, and Maria Carolina (a sister of the executed [[Marie Antoinette]]) made use of Lady Hamilton to induce Nelson to carry out her vengeance.<ref name=EB1911/>

==Third Coalition==
The king returned to Naples soon afterwards,{{when?|date=October 2025}} and ordered the execution of several hundred French [[Wartime collaboration|collaborators]]. This stopped only when the French successes forced him to agree to a treaty which included amnesty for members of the French party. When the [[War of the Third Coalition]] broke out between France and the [[Austrian Empire]] in 1805, Ferdinand signed a treaty of neutrality with the former. A few days later, Ferdinand allied himself with Austria and allowed an [[Anglo-Russian occupation of Naples|Anglo-Russian force]] to land at Naples.<ref name=EB1911/>

[[File:Piastra 1805.jpg|thumb|left|[[Neapolitan piastra|Piastra]] of Ferdinand IV of [[Kingdom of Naples|Naples]], dated 1805]]

The French victory at the [[Battle of Austerlitz]] on 2 December enabled Napoleon to launch an [[Invasion of Naples (1806)|invasion of the Kingdom of Naples]]. Ferdinand fled to [[Palermo]] on 23 January 1806, followed soon after by his wife and son, and on 14 February 1806 the French again entered Naples. Napoleon declared that the [[House of Bourbon|Bourbon]] dynasty had forfeited the crown, and proclaimed his brother [[Joseph Bonaparte|Joseph]] King of Naples and Sicily. But Ferdinand continued to reign over the latter kingdom (becoming the first King of Sicily in centuries to actually reside there) under British protection.<ref name=EB1911/>

Parliamentary institutions of a feudal type had long existed on the island, and [[Lord William Bentinck]], the British minister, insisted on a reform of the constitution on English and French lines. The king indeed practically [[abdicated]] his power, appointing his son Francis as regent, and the queen, at Bentinck's insistence, was [[exile]]d to Austria, where she died in 1814.<ref name=EB1911/>

==Restoration==
[[File:Vincenzo Camuccini - Ritratto di Ferdinando I delle due Sicilie.jpg|thumb|right|''Portrait of Ferdinand I of the Two Sicilies'' by [[Vincenzo Camuccini]], 1818-1819]]

After the fall of Napoleon, [[Joachim Murat]], who had succeeded Joseph Bonaparte as king of Naples in 1808, was dethroned in the [[Neapolitan War]] in 1815, and Ferdinand returned to Naples. By a secret treaty he had bound himself not to advance further in a constitutional direction than Austria should at any time approve; but, though on the whole he acted in accordance with [[Klemens Wenzel von Metternich|Metternich]]'s policy of preserving the ''[[status quo]]'', and maintained with but slight change Murat's laws and administrative system. Ferdinand took advantage of the situation to abolish the Sicilian constitution, in violation of his oath, and to proclaim the union of the two states into the [[Kingdom of the Two Sicilies]] (12 December 1816).<ref name=EB1911/>

Ferdinand was now completely subservient to Austria, an Austrian, [[Count Nugent]], being even made commander-in-chief of the army. For the next four years, Ferdinand reigned as an [[absolute monarch]] within his domain, granting no constitutional reforms.

==1820 revolution==
[[File:Palermo insurrection of 1820.jpg|thumb|left|Palermo insurrection of 1820]]

The suppression of liberal opinion caused an alarming spread of the influence and activity of the secret society of the [[Carbonari]], which in time affected a large part of the army.<ref name=EB1911/> In July 1820, a military revolt broke out under General [[Guglielmo Pepe]], and Ferdinand was terrorised into signing a constitution on the model of the [[Spanish Constitution of 1812]]. On the other hand, a revolt in [[Sicily]], in favour of the recovery of its independence, was suppressed by Neapolitan troops.

The success of the military revolution at Naples seriously alarmed the powers of the [[Holy Alliance]], who feared that it might spread to other Italian states and so lead to a general European conflagration. The [[Troppau Protocol]] of 1820 was signed by Austria, [[Prussia]] and Russia, although an invitation to Ferdinand to attend the adjourned [[Congress of Laibach]] (1821) was issued at which he failed to distinguish himself. He had twice sworn to maintain the new constitution but was hardly out of Naples before he repudiated his oaths and, in letters addressed to all the sovereigns of Europe, declared his acts to have been null and void. Metternich had no difficulty in persuading the king to allow an Austrian army to march into Naples "to restore order".<ref name=EB1911/>

The Neapolitans, commanded by General Pepe, made no attempt to defend the difficult [[defile (geography)|defile]]s of the [[Abruzzi]],<ref name=EB1911>{{EB1911|wstitle=Ferdinand IV. of Naples|volume=10|pages=264–265|inline=1}}</ref> and were defeated at [[Battle of Rieti]] (7 March 1821). The Austrians entered Naples.

==Later years==
Following the Austrian victory, the Parliament was dismissed and Ferdinand suppressed the Liberals and Carbonari. The victory was used by Austria to force its grasp over Naples' domestic and foreign policies. [[Count Charles-Louis de Ficquelmont]] was appointed as the Austrian [[ambassador]] to Naples, practically administering the country as well as managing the occupation and strengthening Austrian influence over Neapolitan elites.

Ferdinand died in Naples on 4 January 1825. He was the last surviving child of Charles III.
