Final answer:
Georges Danton was a key figure in the French Revolution but was never the leader of the Committee of Public Safety. It was Maximilien Robespierre who led the Committee during the Reign of Terror. Danton was executed by guillotine in April 1794 due to his opposition to the regime's violent measures.
Step-by-step explanation:
When questioning when Georges Danton became the leader of the Committee of Public Safety, it's important to clarify that Danton was indeed a prominent figure in the early stages of the French Revolution but he was never the leader of the Committee of Public Safety. Instead, it was Maximilien Robespierre who came to dominate the Committee and the political arena, particularly during the Reign of Terror.
Danton, known for his initial support of the revolution, later expressed disagreement with the extreme measures taken during the Reign of Terror, leading to his execution by guillotine in April 1794. Danton's execution was a symbol of the radical and violent phase of the revolution that sought to silence dissent. The Reign of Terror came to an end with the execution of Robespierre and his followers in July 1794, marking a shift away from Jacobin radicalism toward a more moderate government, known as the Directory.
