 Following the Congress of Vienna in 1815, the political and social Italian unification movement, or "Risorgimento", emerged to unite Italy consolidating the different states of the peninsula and liberate it from foreign control.A prominent radical figure was the patriotic journalist Giuseppe Mazzini, member of the secret revolutionary society "Carbonari" and founder of the influential political movement Young Italy in the early 1830s, who favoured a unitary republic and advocated a broad nationalist movement.His prolific output of propaganda helped the unification movement stay active.
