Deutsche Arbeiterpartei
Further pressure from the political right came in 1923 with the Beer Hall Putsch (aka Munich Putsch), a failed power seizure staged by the Nazi Party under Adolf Hitler in Munich. In 1920, the German Workers' Party had become the National Socialist German Workers' Party (NSDAP), or Nazi party, which would eventually become a driving force in the collapse of Weimar. Hitler named himself as chairman of the party in July 1921. On 8 November 1923, the "Kampfbund", in a pact with Erich Ludendorff, took over a meeting by Bavarian prime minister Gustav von Kahr at a beer hall in Munich.
