22. In 1917, what party did Leon Trotsky join?
From Quiz The Rise and Fall of Leon Trotsky
Answer:
Bolshevik
After escaping exile, Trotsky spent the next decade touring Vienna, Paris, Switzerland, Spain, and the United States while writing, organizing, and generally arguing for revolutionary socialism. He tried to bring the Bolsheviks and Mensheviks together, refusing to commit fully to either version of socialism.
The events of 1917 changed everything. Trotsky returned to Russia after the February Revolution and quickly found that his positions had moved much closer to Lenin's than to any other socialist faction. Trotsky joined the Bolsheviks, and his own organization, the Mezhraiontsy (Inter-District Group), merged with the party in August 1917.
After just a couple months, he had become one of the party's leading figures, serving as chairman of the Petrograd Soviet and playing a major role in planning and directing the October Revolution. Revolutionary politics, as it turns out, can be tricky. Trotsky has spent almost as much time criticizing Lenin over the years as agreeing with him.
