SolvedSources: ALast updated: 14 October 2026

Leon Trotsky, one of the leaders of the Soviet revolution, was exiled after his conflict with Stalin and from 1937 lived in the Coyoacán district of Mexico City. Having survived an armed raid on his house in May 1940, he was attacked with an ice axe in his study on 20 August 1940 by a Soviet NKVD agent who had infiltrated his circle under a false identity, and died in hospital the next day. The assassin was seized at the scene, convicted of murder in Mexico and served 20 years; on his release in 1960 he was decorated as a Hero of the Soviet Union. Trotsky's house in Coyoacán is now a museum open to visitors.
