In 1921, due to the Occupation of the Ruhr by French and Belgian troops he moved to Detmold. That same year he founded the "Cheruskerbund - Heimatbund für Lippe", which in 1924 was incorporated into "Der Stahlhelm". Teudt joined the German National People's Party (DNVP). He likely joined the "" in 1924 and in 1925 supported the "Nationalsozialistische Freiheitsbewegung Deutschlands". In 1928/29, he became "Gauherr" or "Deutschmeister" of the "Deutschbund" in Detmold. Teudt founded the "Vereinigung der Freunde germanischer Vorgeschichte" in 1928 and in 1929 published the book "Germanische Heiligtümer". Though his ideas overlapped with those of Hermann Wirth and Wirth published some articles in Teudt's monthly "Germanien", after the Nazi takeover of power the two became competitors.
