Final answer:
Robespierre's quote about the 'other task' refers to the Reign of Terror, which was a period of extreme violence and repression during the French Revolution aimed at protecting the revolutionary government from threats and ensuring the survival of republican ideals.
Step-by-step explanation:
When Robespierre mentioned that "the revolution imposes on you another task," he was alluding to the necessary actions required to protect the revolutionary government from internal and external threats during the tumultuous period of the French Revolution. This task involved the implementation of the Reign of Terror, a period of violent repression led by Robespierre and the Committee of Public Safety. This policy aimed to employ terror as a tool to lead enemies of the revolution, effectively silencing counterrevolutionaries and ensuring the survival of republican ideals. Arrests, imprisonments, and guillotine executions became rampant as those perceived to be a threat to the newly established republic, including aristocrats, émigrés, and opposing Jacobins, were swiftly dealt with. This phase eventually concluded with a backlash against the extreme measures, leading to Robespierre's execution and the end of the Terror.
