[7] In the early days of the German revolution, the Council of the People's Deputies, the revolutionary government led by Friedrich Ebert of the Social Democratic Party, needed reliable troops in Berlin to protect its position.
[6] Freikorps units suppressed the Marxist Spartacist uprising and were responsible for the extrajudicial executions of revolutionary communist leaders Karl Liebknecht and Rosa Luxemburg on 15 January 1919.
The Kapp Putsch of March 1920, a failed attempt to overthrow the government of the Weimar Republic, drew its military support from the Freikorps, in particular the Marinebrigade Ehrhardt.
Some Freikorps members were then accepted into the Reichswehr, Germany's official army, but more joined the Nazi Stormtroopers (SA), illegal far right formations such as the Organisation Consul, or groups such as the Stahlhelm that were associated with political parties.
The Citizens' Defense paramilitary groups were voluntary, honorary associations based on part-time membership that performed self-protection tasks in local areas.
As a result of the Allied disarmament requirements, the Citizens' Defense forces at Reich level were released from their military subordination and placed under the control of the individual state ministries.
