Giuseppe Mazzini Giuseppe Mazzini was an Italian revolutionary, born in Geneva on June 22, 1807 in a middle class family. He was a patriot, political activist, writer, founder of young Italy and played very important role in liberal nationalism who strived to found a unified democratic republic of Italy. He was one of the three revolutionaries who made a significant contribution in Italian unification. His efforts led to the unification of Italy. He believed in single unified republic instead of being a patchwork of small state kingdoms so in 1830, he joined the revolutionary Carbonari (a Young Italy), whose basic principle was the union of the several states and kingdoms into one republic. In 1831, at the age of 24 he was sent into exile for attempting a revolution in Liguria. He founded underground societies like Young Italy in Marseilles, and Young Europe in Berne. To evoke people's reaction Mazzini wrote several essays that voiced the injustice to the working class such as the peasants, professionals, artist, and intellectuals. He was elected as a member of Constituent Assembly and acquired the responsibilities of framing a constitution for the roman public.
