Deutsche Arbeiterpartei (DAP) — German Workers' Party. This was formed in 1919 by Anton Drexler, with Gottfried Feder, Dietrich Eckart and Karl Harrer, and derived in part from the Thule Society, the cover organization of the occult ariosophist Germanenorden. This party added the adjective "National Socialist" in its name and became the "National Socialist German Workers' Party" (NSDAP) in 1920. (Against the government) Deutsche Reformpartei — German Reform Party (splinter party). Deutschnationale Volkspartei (DNVP) — German National People's Party. It presented itself as a volksgemeinschaft or non-class party. It included remnants from the German Conservative Party, the Free Conservative Party, the Völkische movement, the Christian Social movement, and the Pan-German Association. It established two labor unions; one for the blue-collar worker (the DNAB) and one for the white-collar worker (DNAgB), which had been politically unimportant. The DNVP was the main authoritarian right party of Weimar Germany but moved to the radical right after coming under the control of press baron Alfred Hugenberg in 1928. It organized the National Opposition in 1929, together with leaders of Der Stahlhelm, Hjalmar Schacht, the president of the Reichsbank, and the Nazi Party, to oppose Chancellor Hermann Müller's Grand Coalition. It joined in coalition with Hitler's government in January 1933. (Against the government) Deutschsoziale Partei (DSP) — German Social Party.
