Final answer:
The Reign of Terror, a period of intensified repression and violence during the French Revolution, began in 1793 and ended with the execution of Robespierre and his supporters on July 27, 1794. It lasted approximately one year and a month.
Step-by-step explanation:
Duration of the Reign of Terror
The Reign of Terror refers to the period of the French Revolution marked by extreme violence and systematic executions. This period began in 1793, following the execution of King Louis XVI, and was characterized by the aggressive suppression of dissent by the revolutionary government. It was principally overseen by Maximilien Robespierre and the Committee of Public Safety, which implemented policies leading to the arrest and execution of many using the guillotine. This period of violent repression lasted until July 27, 1794, when Robespierre and his supporters were overthrown and executed, marking the end of the Terror.
Dissension within the revolutionary government, combined with the reduced external threat to France, led to the fall of Robespierre and the cessation of the Terror. Following the end of the Terror, there was a shift towards a more conservative government with the establishment of the Directory, although this new government struggled with internal conflicts and challanges, eventually leading to the rise of Napoleon Bonaparte.
