A pioneer movement is an organization for chilren operated by a communist party. Typically children enter into the organization in elementary school and continue until adolescence. The adolescents then typically joined Komsomol or a similar organization. Prior to the 1990s there was a wide cooperation between pioneer and similar movements of about 30 countries, coordinated by the international organization, International Committee of Children's and Adolescents' Movements (French: Comité international des mouvements d'enfants et d'adolescents, CIMEA), founded in 1958, with headquarters in Budapest.
