This biography reveals the life of one of the American left's most controversial and charismatic figures in the early twentieth century: anarchist, activist, and revolutionary Carlo Tresca. Emigrating to America at age twenty-five from Italy, Tresca became a leader in the fight for workers' rights, alongside activists like Elizabeth Gurley Flynn and Emma Goldman. Tresca played many roles for his cause: newspaper editor, labor agitator and organizer, civil libertarian, anti-fascist, and an indomitable foe of Stalinism. He continued to fight for the rights of the oppressed until gunned down by Mafioso Carmine Galante, a crime which would never be prosecuted. This engaging book not only relates Tresca's adventure-filled story, but brings to life the volatile world of radical politics in early twentieth century America.
