Leon Trotsky

Leon Trotsky is primarily known for his role as a key figure in the Bolshevik Revolution and as a prominent Marxist theorist. His writings on revolutionary strategy and the nature of the Soviet state are highly influential.

Among his most significant works are "The History of the Russian Revolution," which provides a detailed account from a participant's perspective, and "My Life," his autobiography. "Permanent Revolution" also outlines his key theoretical contributions.

While he is primarily known as Leon Trotsky, he used several pseudonyms during his revolutionary career, including 'Pero' and 'Antid Oto,' to evade Tsarist authorities.
