Final answer:
The removal of Maximilien Robespierre from power in 1794 ended the Reign of Terror in the French government.
Step-by-step explanation:
The event that changed in 1794, taking away the emergency that was fueling the radicals in the French government and therefore the Reign of Terror, was the removal of Maximilien Robespierre from power. Robespierre was a key figure in the radical Jacobin Party and had been leading the Reign of Terror, which involved the execution of thousands of perceived enemies of the revolutionary government. However, by 1794, opposition to Robespierre's repressive policies had grown, and he was executed along with other leaders of the Terror on the guillotine.
