What does it take to fight for—and actually win—a socialist revolution? The Bolshevik party played a decisive role in the October 1917 Russian Revolution that brought the world's first workers' government to power, yet the significance of the revolution and its mass character have all too often been distorted by the legacy of what came after in the form of Stalinism. This talk examines the events that led to the Bolsheviks' successful seizure of power; the relationship of the party to the Russian working class; and the role of revolutionary organization in turning the desire to fight for a better world into reality.
