FRANCIS II. (1836-1894), king of the Two Sicilies, son of Ferdinand II. and Maria Cristina of Savoy, was the last of the Bourbon kings of Naples. His education had been much neglected and he proved a man of weak character, greatly influenced by his stepmother Maria Theresa of Austria, by the priests, and by the _Camarilla_, or reactionary court set. He ascended the throne on the death of his father (22nd of May 1859). As prime minister he at once appointed Carlo Filangieri, who, realizing the importance of the Franco-Piedmontese victories in Lombardy, advised Francis to accept the alliance with Piedmont proposed by Cavour. On the 7th of June a part of the Swiss Guard mutinied, and while the king mollified them by promising to redress their grievances, General Nunziante collected other troops, who surrounded the mutineers and shot them down. The incident resulted in the disbanding of the whole Swiss Guard, the strongest bulwark of the dynasty. Cavour again proposed an alliance to divide the papal states between Piedmont and Naples, the province of Rome excepted, but Francis rejected an idea which to him savoured of sacrilege. Filangieri strongly advocated a constitution as the only measure which might save the dynasty, and on the king's refusal he resigned. Meanwhile the revolutionary parties were conspiring for the overthrow of the Bourbons in Calabria and Sicily, and Garibaldi was preparing for a raid in the south. A conspiracy in Sicily was discovered and the plotters punished with brutal severity, but Rosalino Pilo and Francesco Crispi had organized the movement, and when Garibaldi landed at Marsala (May 1860) he conquered the island with astonishing ease. These events at last frightened Francis into granting a constitution, but its promulgation was followed by disorders in Naples and the resignation of ministers, and Liborio Romano became head of the government. The disintegration of the army and navy proceeded apace, and Cavour sent a Piedmontese squadron carrying troops on board to watch events. Garibaldi, who had crossed the straits of Messina, was advancing northwards and was everywhere received by the people as a liberator. Francis, after long hesitations and even an appeal to Garibaldi himself, left Naples (6th of September) with his wife Maria Sophia, the court, the diplomatic corps (the French and English ministers excepted), and went by sea to Gaeta, where a large part of the army was concentrated. The next day Garibaldi entered Naples, was enthusiastically welcomed, and formed a provisional government. King Victor Emmanuel had decided on the invasion of the papal states, and after occupying Romagna and the Marche entered the Neapolitan kingdom. Garibaldi's troops defeated the Neapolitan royalists on the Volturno (1st and 2nd of October), while the Piedmontese captured Capua. Only Gaeta, Messina, and Civitella del Tronto still held out, and the siege of the former by the Piedmontese began on the 6th of November 1860.
