German Communism refers to the political movement in Germany that aimed to establish a communist society based on the ideas of Karl Marx and Friedrich Engels. It gained prominence after World War I, particularly with the formation of the Spartacist League in 1916, which later became the Communist Party of Germany (KPD). The movement sought to overthrow the Weimar Republic and implement a socialist state. The most notable event associated with German Communism was the German Revolution of 1918-1919, which led to the short-lived German Council Republic. Despite initial support, the KPD faced significant opposition from both the government and rival socialist factions, leading to its decline by the late 1920s.
