100 years ago, Europe was beset by WWI.
Just 3 years later, Lenin's Bolshevik Party led workers to power in Russia.
How did a party of only 8,000 members in February 1917 grow to a quarter of a million in less than nine months, and win the majority of workers, peasants, and soldiers to take power in a virtually bloodless October Revolution?
How was this party constructed? How were its members educated and developed? How did it weather repression and the ebbs and flows of the struggle? What practical lessons can 21st-century socialists gain from a careful study of Bolshevism?
