The Jilava massacre took place during the night of November 26, 1940, at Jilava penitentiary, near Bucharest, Romania. Sixty-four political detainees were killed by the Iron Guard (Legion), with further high-profile assassinations in the immediate aftermath. It came about halfway through the fascist National Legionary State and led to the first open clash between the Guard and "conducător" Ion Antonescu, who ousted the Legion from power in January 1941.
