The Deutsches Jungvolk in der Hitlerjugend (pronounced [ˈdɔʏtʃəs ˈjʊŋfɔlk]; DJ, also DJV; German for "German Youngsters in the Hitler Youth") was the separate section for boys aged 10 to 13 of the Hitler Youth organisation in Nazi Germany. Through a programme of outdoor activities, parades and sports, it aimed to indoctrinate its young members in the tenets of Nazi ideology. Membership became fully compulsory for eligible boys in 1939. By the end of World War II, some had become child soldiers. After the end of the war in 1945, both the Deutsches Jungvolk and its parent organization, the Hitler Youth, ceased to exist.
