The Ruhr uprising (German: Ruhraufstand) or March uprising (Märzaufstand) was an uprising that occurred in the Ruhr region of Germany from 13 March to 6 April 1920. It was a left-wing workers’ revolt triggered by the call for a general strike in response to the Kapp Putsch, then became an armed rebellion when far-left workers used the strike as an opportunity to attempt the establishment of a council republic.[1]
