On this day, January 11th, 1943, Italian-American Carlo Tresca is assassinated in New York City. Tresca was a newspaper editor, orator and labor organizer who was a leader of the Industrial Workers of the World during the early 1900s. Tresca openly condemned fascism, Stalinism, and Mafia trade union involvement. Tresca had been arrested for his involvement in labor strikes and was on parole at the time of his assassination. Tresca also became openly anti-Mafia in his weekly newspaper and was aware of the risk he was taking. After leaving his parole officer on January 11th, he was crossing Fifth Avenue and 13th Street, when a black Ford pulled up next to him and Tresca was shot in the back by an unknown gunman. Although several theories have been examined as to who his assailants were, it is of general opinion that he was assassinated by the Mafia.
