Anarchist Czolgosz shot American President McKinley. He approached him at the beginning of a conference in New York thinking he was an amateur and shot him in the tripe. Leon Czolgosz was executed in the electric chair in October, 28 years old. The persecution of anarchists spread throughout the United States and several anarchist groups rejected their action and even considered it a spy. However, its action coincides with the strategy that anarchism used in the early nineteenth century to seek the murder of significant people worldwide, the expansion of anarchism and social transformation. His last words were: "I killed the president because he was the enemy of good people, of good workers. I don't regret my crime."
