On the extreme left of the political spectrum, the Communist Party (KPD) in Germany after the First World War drew its support mainly from the workers. They based their ideas on a communist revolution where the workers rise up against the ruling classes. This was the dream of German Communists such as Karl Liebknecht and Rosa Luxemburg. They wanted to achieve something similar to the Russian Revolution of 1917, when a Communist State was created. The Communist Party detested the Weimar Republic.
