But democracy was no simple task, and the Provisional Government that took over the country's administration needed the cooperation of the Petrograd Soviet, an organization that united leftist industrial laborers, to function and survive. Under the uncertain leadership of Alexander Kerensky, however, the Provisional Government mismanaged Russia's continuing involvement in the war, prompting angry reactions from the Petrograd workers, who drifted further and further to the left. The Bolsheviks, a communist group led by Vladimir Lenin, seized the political opportunity from this confusion and launched a second revolution in Russia during the same year. The communists violently overthrew the fragile liberal-socialist order in October, after which Russia witnessed several years of civil war between communists and conservatives wishing to restore the monarchy.
