Following the abortive Beer Hall Putsch (in November 1923), Nazi youth groups ostensibly disbanded, but many elements simply went underground, operating clandestinely in small units under assumed names. In April 1924, the "Jugendbund der NSDAP" was renamed "Grossdeutsche Jugendbewegung" (Greater German Youth Movement). On 4 July 1926, the "Grossdeutsche Jugendbewegung" was officially renamed "Hitler Jugend Bund der deutschen Arbeiterjugend" (Hitler Youth League of German Worker Youth). This event took place a year after the Nazi Party was reorganised. The architect of the re-organisation was Kurt Gruber, a law student from Plauen in Saxony.
