League of German Girls
It was called the "Jungmädelbund" in German, and commonly abbreviated in period and contemporary historical writings as JM. Since this was a girls' organization, it fell under the League of German Girls (BDM), which was led by the "BDM-Reichsreferentin" (National Speaker of the BDM), who reported to the overall head of the Hitler Youth, Baldur von Schirach (who was later succeeded by Artur Axmann).
