in Sicily, with Palermo as his capital. After Napoleon's defeat, King Ferdinand IV was restored by the Congress of Vienna of 1815 as Ferdinand I of the Two Sicilies. He established a concordat with the Papal States, which previously had a claim to the land. There were several rebellions on the island of Sicily against the King Ferdinand II, but the end of the kingdom was only brought about by the Expedition of the Thousand in 1860, led by Garibaldi, an icon of the Italian unification, with the support of the House of Savoy and their Kingdom of Sardinia with its economic, political and cultural powerhouse in Northern Italy. The expedition resulted in a striking series of defeats for the Sicilian armies against the growing troops of Garibaldi. After the capture of Palermo and Sicily, he disembarked in Calabria and moved towards Naples, while in the meantime the Piedmontese also invaded the Kingdom from the Marche. The last battles fought were that of the Volturnus in 1860 and the siege of Gaeta, where King Francis II had sought shelter, hoping for French help, which never came. The last towns to resist Garibaldi's expedition were Messina (which capitulated on 13 March 1861) and Civitella del Tronto (which capitulated on 20 March 1861). The Kingdom of the Two Sicilies was dissolved and annexed to the new Kingdom of Italy, founded in the same year. Southern and Northern Italy in 1860 At the time of Italian unification, the gap between the former Northern states of Italy and the Southern two Sicilies was significant: Northern Italy had about 75,500 kilometers of roads and 2,316 kilometers of railroads, combined with a wide range of canals connected to rivers for freight transportation; iron and steel production was 17,000 tons per year. By contrast, in the former Bourbon Southern state, there were 14,700 kilometers of roads, 184 kilometers of railroads (only around Naples), no canals connected to rivers and iron and steel production was 1,500 tons per year. In 1860, illiteracy rates on the Italian peninsula averaged 75%, with the lowest level of 54% in the northwestern Kingdom of Sardinia (also known as "Piedmont"), and the highest in the south, where illiteracy in the Kingdom of the Two Sicilies reached 87%. In 1860 the southern merchant navy amounted to 260,000 tons, whereas the northern merchant navy came to 347,000 tons, apart from the Venetian navy annexed in
