Task: Question Answering
Input (English): Passage: In 1918, party membership was approximately 200,000. In the late 1920s under Stalin, the party engaged in an intensive recruitment campaign, the "Lenin Levy", resulting in new members referred to as the Lenin Enrolment, from both the working class and rural areas. This represented an attempt to "proletarianize" the party and an attempt by Stalin to strengthen his base by outnumbering the Old Bolsheviks and reducing their influence in the Party. In 1925, the party had 1,025,000 members in a Soviet population of 147 million. In 1927, membership had risen to 1,200,000. During the collectivization campaign and industrialization campaigns of the first five-year plan from 1929 to 1933, party membership grew rapidly to approximately 3.5 million members. However, party leaders suspected that the mass intake of new members had allowed "social-alien elements" to penetrate the partys ranks and document verifications of membership ensued in 1933 and 1935, removing supposedly unreliable members. Meanwhile, the party closed its ranks to new members from 1933 to November 1936. Even after the reopening of party recruiting, membership fell to 1.9 million by 1939. Nicholas DeWitt gives 2.307 million members in 1939, including candidate members, compared with 1.535 million in 1929 and 6.3 million in 1947. In 1986, the CPSU had over 19 million membersapproximately 10% of the Soviet Unions adult population. Over 44% of party members were classified as industrial workers and 12% as collective farmers. The CPSU had party organizations in 14 of the Soviet Unions 15 republics. The Russian Soviet Federative Socialist Republic itself had no separate Communist Party until 1990 because the CPSU controlled affairs there directly.
