Militant League for German Culture
On 31 March 1925 Ziegler became a member of the Nazi Party, with his membership number being the comparatively low 1317. From 1925 to 1931 he worked under Wilhelm Frick in Thuringia, serving as deputy gauleiter from 1930 to 1931. In 1928 he was appointed head of the Militant League for German Culture. It was also Ziegler who in 1926 came up with the name "Hitler-Jugend" (Hitler Youth) for the Nazi youth movement. Ziegler was a close friend of the Schirach family and in 1925 he introduced Baldur von Schirach, who would go on to lead the Hitler Youth, to Adolf Hitler.
