What was not one of the Bolsheviks leaders of the Russian revolutions?

One of the prominent figures not associated with the Bolsheviks during the Russian revolutions was Leon Trotsky. While he played a crucial role in the October Revolution and was a key leader within the Bolshevik party, his later opposition to Joseph Stalin led to his exile and eventual assassination in 1940. Other notable figures, such as Alexander Kerensky, were part of the provisional government and not aligned with the Bolshevik ideology.
