The Spartacist revolt in January 1919 posed a significant challenge to the Weimar government, leading Chancellor Ebert to use military force to suppress it, resulting in the execution of key leaders and a split among left-wing groups. Subsequent protests and strikes across Germany in response to economic issues were largely local and disorganized, but notable events included the rise and fall of a left-wing government in Bavaria and the formation of the Ruhr Army to resist right-wing attacks. Despite the left's attempts, the Weimar government managed to survive due to its military support and the division among both left and right extremists.
