Claim: On July 29, 1900, Gaetano Bresci an Italian-American Anarchist, assassinated Umberto I of Italy.
Evidence: Gaetano Bresci (Italian pronunciation: [ɡaeˈtaːno ˈbreʃʃi; November 10, 1869 – May 22, 1901) was an Italian anarchist who assassinated King Umberto I of Italy on July 29, 1900. Bresci was born on November 10, 1869, at Coiano, in Prato, Tuscany, and emigrated from Italy to the United States in his late twenties, making his living as a weaver in Paterson, New Jersey, which had a large Italian-American community. Bresci had thought of killing Italian King Umberto I when he lived in Italy. While the king was visiting Monza, on July 29, 1900, Bresci shot him four times with a five-shot .32 revolver. A monument, the Cappella Espiatoria, was later erected on the spot where the king was murdered. Umberto I (Italian: Umberto Rainerio Carlo Emanuele Giovanni Maria Ferdinando Eugenio di Savoia; 14 March 1844 – 29 July 1900), nicknamed the Good (Italian: il Buono), was the King of Italy from 9 January 1878 until his assassination on 29 July 1900.
