Rat der Volksbeauftragten
A rift developed between the MSPD and USPD after Ebert called upon the OHL (Supreme Army Command) for troops to put down a mutiny by a leftist military unit on 23/24 December 1918, in which members of the "Volksmarinedivision" (People's Army Division) had captured the city's garrison commander Otto Wels and occupied the "Reichskanzlei" (Reich Chancellery) where the "Council of the People's Deputies" was situated. The ensuing street fighting left several dead and injured on both sides. The USPD leaders were outraged by what they believed was treachery by the MSPD, which, in their view, had joined with the anti-communist military to suppress the revolution. Thus, the USPD left the "Council of the People's Deputies" after only seven weeks. On 30 December, the split deepened when the Communist Party of Germany (KPD) was formed out of a number of radical left-wing groups, including the left wing of the USPD and the Spartacus League group.
