The Kingdom of the Two Sicilies () was a kingdom in Southern Italy from 1816 to 1860. The kingdom was the largest sovereign state by population and size in Italy before Italian unification, comprising Sicily and all of the Italian Peninsula south of the Papal States, which covered most of the area of today's Mezzogiorno. The kingdom was formed when the Kingdom of Sicily merged with the Kingdom of Naples, which was officially also known as the Kingdom of Sicily. Since both kingdoms were named Sicily, they were collectively known as the "Two Sicilies" (Utraque Sicilia, literally "both Sicilies"), and the unified kingdom adopted this name. The king of the Two Sicilies was overthrown by Giuseppe Garibaldi in 1860, after which the people voted in a plebiscite to join the Savoyard Kingdom of Sardinia. The annexation of the Kingdom of the Two Sicilies completed the first phase of Italian unification, and the new Kingdom of Italy was proclaimed in 1861. The Two Sicilies were heavily agricultural, like the other Italian states. Name The name "Two Sicilies" originated from the partition of the medieval Kingdom of Sicily. Until 1285, the island of Sicily and the Mezzogiorno were constituent parts of the Kingdom of Sicily. As a result of the War of the Sicilian Vespers (1282–1302), the King of Sicily lost the Island of Sicily (also called Trinacria) to the Crown of Aragon, but remained ruler over the peninsular part of the realm. Although his territory became known unofficially as the Kingdom of Naples, he and his successors never gave up the title "King of Sicily" and still officially referred to their realm as the "Kingdom of Sicily". At the same time, the Aragonese rulers of the Island of Sicily also called their realm the "Kingdom of Sicily". Thus, there were two kingdoms called "Sicily": hence, the Two Sicilies. This is readopted by Two Sicilies national football team, an Italian football club since December 2008. Background Origins of the two kingdoms In 1130 the Norman king Roger II formed the Kingdom of Sicily by combining the County of Sicily with the southern part of the Italian Peninsula (then known as the Duchy of Apulia and Calabria) as well as with the Maltese Islands. The capital of this kingdom was Palermo, which is on the island of Sicily. During the reign of Charles I of Anjou (1266–1285), the War of the Sicilian Vespers
