How did the Sicilian revolt of 1860 lead to Garibaldi’s Expedition of the Thousand?

The Sicilian revolt, which began on April 4, 1860, with an insurrection in Palermo known as the Gancia revolt, served as the primary catalyst for Giuseppe Garibaldi to launch his Expedition of the Thousand. Although the initial uprising was quickly suppressed, it spread across the island and demonstrated that Sicilian democrats were capable of overcoming internal divisions to oppose the Bourbon Kingdom of the Two Sicilies.12

Garibaldi, who had grown impatient with the cautious diplomatic strategies of Count Cavour, viewed the unrest as a critical opportunity to advance the Risorgimento. He decided to act on his own initiative to support the democratic revival in the south. By May 1860, he had organized a volunteer force that sailed from Liguria to Sicily, landing at Marsala on May 11. The indigenous revolutionary ferment and the existing anti-Bourbon sentiment on the island were instrumental in the success of his campaign, which ultimately led to the collapse of Bourbon rule and the unification of southern Italy with the north.12
