What notable event occurred during the convention meeting on July 27-28, 1794?

The notable event that occurred during the convention meeting on July 27-28, 1794, was the execution of Robespierre and his followers. This moment marked a significant turning point in the French Revolution, as Robespierre, who had been a dominant figure in the Reign of Terror, was arrested along with several of his allies. His execution effectively ended the intense period of political purges that characterized the Reign of Terror, which had sought to eliminate perceived enemies of the revolution through radical measures.

The significance of this event lies in the symbolic and political shift that followed. After Robespierre’s downfall, the revolutionary government began to move away from his radical policies, leading to a more moderate phase in the revolution. This transition marked a crucial pivot towards stabilizing the political climate in France, ultimately culminating in the establishment of new governing structures, although it would take some time for the effects of Robespierre's execution to play out fully in French politics.
