One of the first major events in the arts during the Weimar Republic was the founding of an organization, the (November Group) on December 3, 1918. This group was established in the aftermath of the November beginning of the German Revolution of 1918–1919, when Communists, anarchists and pro-republic supporters had fought in the streets for control of the government. In 1919, the Weimar Republic was established. Around 100 artists of many genres who identified themselves as avant-garde joined the November Group. They held 19 exhibitions in Berlin until the group was banned by the Nazi regime in 1933. The group also had chapters throughout Germany during its existence, and brought the German avant-garde art scene to world attention by holding exhibits in Rome, Moscow and Japan.
