Question

Why do you think something like the Reign of Terror happens during a revolution ?

Answer 1

The Reign of Terror or The Terror (French: la Terreur), is the label given by some historians to a period during the French Revolution. Different historians place the starting date at either 5 September 1793[1] or June 1793[2] or March 1793 (birth of the Revolutionary Tribunal) or September 1792 (September Massacres) or July 1789 (first decapitations)[3], but generally agree on an ending date of July 1794[1][2].

Between June 1793 and the end of July 1794, there were 16,594 official death sentences in France, of which 2,639 were in Paris.[2][4] But the total number of deaths in France was much higher, owning to death in imprisonment, suicide and casualties in foreign and civil war.

Answer 2

Basically, the Reign of Terror was when the power of revolution went to Robespierre's head. This happens because when people see all the change they made happen (like starting off the revolution), they get "Mad" with power and often use their power to simply show that they have it (Like killing off huge amounts of the population).

Hope this Helps!
