Nicola Sacco (April 22, 1891 – August 23, 1927) and Bartolomeo Vanzetti (June 11, 1888 – August 23, 1927) were Italian-born American anarchists who were controversially convicted of murdering a guard and a paymaster during the April 15, 1920 armed robbery of the Slater and Morrill Shoe Company in Braintree, Massachusetts, United States. Seven years later, they were electrocuted in the electric chair at Charlestown State Prison. Both men adhered to an anarchist movement.
