Giuseppe Mazzini

Mazzini founded the secret society Young Italy (Giovine Italia) in Marseille. The organization aimed to achieve Italian unification through popular insurrection and republican government. It recruited thousands of members and inspired uprisings in the 1830s and 1840s.

Mazzini organized an armed invasion of Savoy from Switzerland, intending to spark a republican revolution. The attempt failed due to poor coordination and betrayal, forcing Mazzini into exile. He was sentenced to death in absentia by Piedmontese authorities.

Mazzini became one of the triumvirs governing the short-lived Roman Republic after the pope fled. He implemented progressive reforms including universal male suffrage and freedom of the press. The republic was crushed by French troops in July 1849, and Mazzini returned to exile.

Mazzini organized an ill-fated expedition led by Carlo Pisacane to spark a revolt in the Kingdom of the Two Sicilies. The rebels were quickly defeated and killed by local peasants and Bourbon troops. The failure discredited Mazzini's insurrectionary strategy.
