Sicilian revolution of 1848
The Sicilian revolution of independence of 1848 occurred in a year replete with revolutions and popular revolts. It commenced on 12 January 1848, and therefore was the first of the numerous revolutions to occur that year. Three revolutions against Bourbon rule had previously occurred on the island of Sicily starting from 1800: this final one resulted in an independent state surviving for 16 months. The constitution that survived the 16 months was quite advanced for its time in liberal democratic terms, as was the proposal of an Italian confederation of states. It was in effect a curtain raiser to the end of the Bourbon kingdom of the Two Sicilies which was started by Giuseppe Garibaldi's Expedition of the Thousand in 1860 and culminated with the siege of Gaeta of 1860–1861.
