Sicily
The Expedition of the Thousand led by Giuseppe Garibaldi captured Sicily in 1860, as part of the . The conquest started at Marsala, and native Sicilians joined him in the capture of the southern Italian peninsula. Garibaldi's march was completed with the Siege of Gaeta, where the final Bourbons were expelled and Garibaldi announced his dictatorship in the name of Victor Emmanuel II of Kingdom of Sardinia. Sicily became part of the Kingdom of Sardinia after a referendum where more than 75% of Sicily voted in favour of the annexation on 21 October 1860 (but not everyone was allowed to vote). As a result of the Kingdom of Italy proclamation, Sicily became part of the kingdom on 17 March 1861.
Kingdom of the Two Sicilies
A monarchy over the areas which would later become known as the Two Sicilies existed as one single kingdom, including a peninsular and an insular part, dating from the Middle Ages. 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 actual island of Sicily.
