Junior section called the 'pioneers' established in 1922 for children from 10. In 1926, it was renamed the ‘Komosomol’ and the age range extended to 10-28.
Komsomol helped carry out Party campaigns and assisted the Red Army. The Komsomol assisted with the police, did voluntary social work and set up political clubs to instil socialist value.
But only 6% of elgible children joined but it did grew under Stalin. Not all young people supported them and instead were more interested in Western culture. Thus therewere a small number of secret ‘oppositional’ youth organisations.
