Trial for Trotsky
In Moscow, 17 leading Communists went on trial, accused of participating in a plot engineered by Leon Trotsky to overthrow Stalin’s regime and assassinate its leaders. After a seven-day trial, 13 of them were sentenced to death. Trotsky fled to Mexico where he was assassinated in 1940.
