Prussian Landtag elections in the Weimar Republic

The Free State of Prussia held elections to its Landtag between 1919 and 1933.

[1] From 1919 through 1928, these elections gave a plurality to the SPD.

In 1932 and 1933, the NSDAP (Nazi Party) won pluralities, generally in line with the rest of Germany.

[2][3] The Landtag subsequently was formally abolished as a result of the "Law on the Reconstruction of the Reich" of 30 January 1934 which replaced the German federal system with a unitary state.
