The world’s largest youth organization was founded on October 29, 1918, and accepted young people aged 14 to 28.
In effect, it was a "gateway" to joining the only party in the USSR—the Communist Party, which provided privileges and career advancement. However, expulsion from the Komsomol could ruin one's career.
Most often, expulsions were due to "immoral behavior": various crimes, hooliganism, drunkenness resulting in detention, failure to pay child support, or having children out of wedlock.
This was because Komsomol members were expected to exhibit high moral standards and be exemplary individuals.
Additionally, during the years of political repression, children of “enemies of the people” convicted under political charges could be expelled from the Komsomol.
Members who failed to pay dues to the organization—about 1% of their salary—were also expelled.
