Leon Trotsky was assassinated on August 20, 1940, in Mexico City on the orders of Joseph Stalin. Trotsky, a key figure in the Russian Revolution and a prominent opponent of Stalin's regime, had been living in exile since the late 1920s. Stalin viewed him as a significant threat to his power and sought to eliminate him to consolidate his control over the Soviet Union. The assassination was carried out by Ramón Mercader, a Spanish communist covertly working for the Soviet secret police.
