Having met Anton Drexler through his work, he met with the group of men that formed the German Workers' Party (DAP): Drexler, Gottfried Feder and Dietrich Eckart, joining their party in January 1920. In 1920 he met Hitler in the regional press office of the Reichswehr (Army of the Weimar Republic) and joined the renamed National Socialist German Workers' Party in March 1920. In the fall of 1920, he began his public appearances in Passau. On 15 May 1921 he was made editor-in-chief of "Völkischer Beobachter", the Party newspaper, turning out a series of posters and a book attacking the Jews.
