The German Centre Party (German: Deutsche Zentrumspartei or just Zentrum) is a lay Catholic political party in Germany, primarily influential during the Kaiserreich and the Weimar Republic. In English it is often called the Catholic Centre Party. Formed in 1870, it battled the Kulturkampf which the Prussian government launched to reduce the power of the Catholic Church. It soon won a quarter of the seats in the Reichstag (Imperial Parliament), and its middle position on most issues allowed it to play a decisive role in the formation of majorities. Its support for the Nazi Party in the early 1930s was decisive in the passage of the Enabling Act, whereby Adolf Hitler assumed dictatorial powers and the Nazi party became the only legally permitted party in the country.
