One reason the Hitler Youth so easily developed was that regimented organisations, often focused on politics, for young people and particularly adolescent boys were a familiar concept to German society in the Weimar Republic. Numerous youth movements existed across Germany prior to and especially after World War I. They were created for various purposes. Some were religious and others were ideological, but the more prominent ones were formed for political reasons, like the Young Conservatives and the Young Protestants. Once Hitler came onto the revolutionary scene, the transition from seemingly innocuous youth movements to political entities focused on Hitler was swift.
