What are leon trotskys crimes?

Leon Trotsky, a key figure in the Russian Revolution, faced accusations of various crimes primarily related to his opposition to Joseph Stalin's policies and his role in the Bolshevik regime. He was accused of promoting Trotskyism, which advocated for permanent revolution and criticized Stalin's concept of socialism in one country. Additionally, he was blamed for the failures of the Red Army during the Russian Civil War and for fostering dissent within the Communist Party. Ultimately, these allegations led to his exile and assassination in 1940, as Stalin sought to eliminate any threats to his leadership.
