German Democratic PartyThe German Democratic Party, or Deutsche Demokratische Partei (DDP), was founded by leaders of the former Progressive Party and the left wing of the National Liberal Party in the early days of the Weimar Republic. Their leaders included Walther Rathenau, Eugen Schiffer, Otto Preuss, Otto Gessler, and Erich Koch-Weser.
The Democrats were a left-wing liberal party, and, along with the Social Democrats, the political party most committed to maintaining a democratic, republican form of government. The party was attacked by some for being a party of Jews and professors (and, indeed, Jews formed one of its most loyal constituencies).
The Democrats did well in the first Reichstag election, and joined the first government of the Weimar Republic as part of the Weimar Coalition of Philipp Scheidemann. They resigned from the government to protest the Treaty of Versailles later that year, but soon returned. In later elections, their showing consistently worsened. An attempted merger with the "Young Germans" to form the German State Party in 1930 failed miserably, and the party's Reichstag deputation became practically insignificant. The party was abolished by the Nazis in 1933.
