The Communist Youth League (Komsomol) was founded in 1917-1918 in urban centers. Its leadership's perception of the peasantry and its quest to maintain a respectable proportion of workers in the membership impeded expansion in rural areas: in the name of “proletarian purity,” many leaders and activists opposed the blanket admission of all but the poorest peasants into their midst. But demographic realities made the Komsomol's outreach to young peasants imperative: peasants made up eighty percent of the Russian population; their children nineteen years of age or younger accounted for half of the rural population in the mid-1920s. More important, the state and the Party had reduced their rural personnel at the end of the civil war and the Komsomol found itself pressured to fill the gap.
