What type of challenge did the Spartacist uprising create for the Weimar Republic?

Correct answer: Left wing revolutionary challenge

The direct answer is option A, a left-wing revolutionary challenge. After the First World War, Germany faced political conflict about the form of the new government. The Spartacists, led by figures such as Rosa Luxemburg and Karl Liebknecht, wanted a socialist revolution and a council-based system influenced by the Russian Revolution. Therefore, their uprising challenged the new democratic Weimar government from the revolutionary left. Option A is correct because it describes both their ideology and their political action. Option B, complete monarchist support, is wrong because monarchists wanted restoration of monarchy, whereas Spartacists wanted a socialist revolutionary order. Option C, colonial expansion, is wrong because the uprising concerned Germany’s internal political system, not overseas empire-building. Option D, peaceful election campaign, is wrong because an uprising is an armed or forceful political challenge, not a normal election campaign. Memory cue: Spartacists equals socialist revolution and left-wing opposition to Weimar.
