Why did Robespierre lose power after French military victories in 1794?

Maximilien Robespierre’s loss of power in July 1794 was directly linked to the success of French military efforts during the French Revolutionary wars.

The Committee of Public Safety had justified the Reign of Terror and strict economic controls—such as the Maximum—as necessary measures to defend the nation against foreign and domestic enemies. However, the decisive French victory against the Austrians at the Battle of Fleurus on June 26, 1794, fundamentally altered the political climate. By reoccupying Belgium and securing the frontier, the military threat that had sustained the radical government diminished.

Consequently, the Terror and the associated social and economic restrictions began to appear unnecessary and oppressive to the public and the National Convention. As the perceived need for such extreme measures evaporated, opposition to Robespierre intensified among his colleagues, leading to his downfall during the Thermidorian Reaction on July 27, 1794.1234
