The All-German People's Party was a minor political party in West Germany active between 1952 and 1957. It was a Christian, pacifist, centre-left party that opposed the re-armament of West Germany because it believed that the remilitarisation and NATO integration would make German reunification impossible, deepen the division of Europe and pose a danger to peace.

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.
