1930 German federal election in the context of "German Democratic Party"

The German Democratic Party (Deutsche Demokratische Partei, DDP) was a liberal political party in the Weimar Republic, considered centrist or centre-left. Along with the right-liberal German People's Party (Deutsche Volkspartei, DVP), it represented political liberalism in Germany between 1918 and 1933. It was formed in 1918 from the Progressive People's Party and the liberal wing of the National Liberal Party, both of which had been active in the German Empire.

After the formation of the first German state to be constituted along pluralist-democratic lines, the DDP took part as a member of varying coalitions in almost all Weimar Republic cabinets from 1919 to 1932. Before the Reichstag elections of 1930, it united with the Volksnationale Reichsvereinigung, which was part of the national liberal Young German Order (Jungdeutscher Orden). From that point on the party called itself the German State Party (Deutsche Staatspartei, DStP) and retained the name even after the Reich Association left the party. Because of the connection to the Reich Association, members of the left wing of the DDP broke away from the party and toward the end of the Republic founded the Radical Democratic Party, which was unsuccessful in parliament. Others joined the Social Democratic Party of Germany (SPD).
