The Reichstag Peace Resolution passed by the Reichstag of the German Empire on 19 July 1917 was an attempt to seek a negotiated peace treaty to end World War I. The resolution called for no annexations, no indemnities, freedom of the seas, and international arbitration. Although it was rejected by the conservative parties, the German High Command, and the Allied powers and thus had no effect on the progress of the war, it brought the moderate parties that supported the resolution into a group that would shape much of the Weimar Republic's politics.

The Centre Party, officially the German Centre Party and also known in English as the Catholic Centre Party, is a Christian democratic political party in Germany. It was most Influential in the German Empire and Weimar Republic. Formed in 1870, it successfully battled the Kulturkampf waged by Chancellor Otto von Bismarck against the Catholic Church. It soon won a quarter of the seats in the Reichstag, and its middle position on most issues allowed it to play a decisive role in the formation of majorities. The party name Zentrum (Centre) originally came from the fact that Catholic representatives would take up the middle section of seats in parliament between the social democrats and the conservatives.
