would remain so until 1933. Over the next few years he was very active as a propaganda speaker throughout Bavaria, and was named a Reichsredner, or national speaker. During a debate in the Landtag in July 1927 concerning a drop in Bavarian tourism, Buttmann ascribed it not to anti-Semitic agitation, but to the presence of Jews in the Alpine spa of Bad Reichenhall, along with other non-German influences such as jazz music, which he denounced using vulgar, racist terms. In September 1932, Buttmann became the head of the Main Department (Hauptabteilung) for Popular Education in the Nazi Party's Reichsleitung (National Leadership). After the Nazi seizure of power, Buttmann was considered by many to be a natural candidate to become the Education Minister in Bavaria but the post instead went to Hans Schemm, the powerful Gauleiter of the Bavarian East March. In October 1933, Buttmann was one of the founding members of Hans Frank's Academy for German Law. In November 1933, Buttmann was elected to the Reichstag from electoral constituency 24, Upper Bavaria-Swabia where he would continue to serve until 1945. From 1933 to 1945 he also served as Chairman of the German Language Association. In 1933 and 1934 he published and edited the journal Völkische Kultur. From 5 May 1933 until 1 October 1935 he served as head of the Department for Cultural Policy in the Reich Ministry of the Interior with the rank of Ministerial Director.
