Explanation: Many of the leaders of the early Soviet Union, instrumental in its success against the democratic socialist provisional government, the anarcho-communists, and the legitimately reactionary White movement, were purged by the Soviet dictator Joseph Stalin (second in the list). He did so to present himself as the only figure of note who was a TRUE revolutionary, after the death of Vladimir Lenin (first in the list), the previous strongman leader of the Soviet Union.
Funny how everyone who had any prestige or revolutionary credentials was a reactionary traitor except for Stalin.
