Ruhr Red Army
The Ruhr Red Army or Red Ruhr Army (German: Rote Ruhrarmee) was a paramilitary of 50,000 to 80,000 left-wing workers that fought in the Ruhr uprising in Weimar Germany from 13 March to 6 April 1920. The Ruhr Red Army was formed in Germany's Ruhr region in reaction to the right-wing Kapp Putsch from left-wing militias that supported the establishment of a council republic.
