8. Philippe Pétain
Once celebrated as a hero of World War I, Marshal Philippe Pétain’s legacy was forever tarnished by his leadership of Vichy France during World War II. Pétain oversaw a government that actively collaborated with Nazi Germany, including the deportation of Jews and suppression of resistance movements. After the war, he was arrested, tried for treason, and sentenced to death—a punishment later commuted to life imprisonment. Pétain’s dramatic fall from grace remains a sobering example of how wartime choices can redefine history.
