At the news of the Russian Revolution of February 1917, exiled revolutionaries from around the world began to flock back to the homeland. Trotsky left New York on 27 March 1917, sailing for St. Petersburg. Bukharin left New York in early April and returned to Russia by way of Japan (where he was temporarily detained by local police), arriving in Moscow in early May 1917. Politically, the Bolsheviks in Moscow were a minority in relation to the Mensheviks and Social Democrats. As more people began to be attracted to Lenin's promise to bring peace by withdrawing from the Great War, membership in the Bolshevik faction began to increase dramatically — from 24,000 members in February 1917 to 200,000 members in October 1917. Upon his return to Moscow, Bukharin resumed his seat on the Moscow City Committee and also became a member of the Moscow Regional Bureau of the party.
