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.
Italy
An Allied invasion of Sicily began in July 1943, leading to the collapse of the Fascist regime and the fall of Mussolini on 25 July. Mussolini was deposed and arrested by order of King Victor Emmanuel III in co-operation with members of the Grand Council of Fascism, who lost faith in him for having led Italy to ruin by allying with Germany. On 8 September, Italy signed the Armistice of Cassibile, ending its war with the Allies. The Germans helped by the Italian fascists shortly succeeded in taking control of northern and central Italy. The country remained a battlefield for the rest of the war, as the Allies were slowly moving up from the south.
