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.
Italians
During the subsequent Swabian rule under the Holy Roman Emperor Frederick II, who spent most of his life as king of Sicily in his court in Palermo, Muslims was progressively eradicated until the massive deportation of the last Muslims of Sicily. As a result of Arab expulsion, many towns across Sicily were left depopulated. By the 12th century, Swabian kings granted immigrants from northern Italy (particularly Piedmont, Lombardy and Liguria), Latium and Tuscany in central Italy, and French regions of Normandy, Provence and Brittany (all collectively known as "Lombards".) settlement into Sicily, re-establishing the Latin element into the island, a legacy which can be seen in the many Gallo-Italic dialects and towns found in the interior and western parts of Sicily, brought by these settlers. It is believed that the Lombard immigrants in Sicily over a couple of centuries were a total of about 200,000.
