Step-by-step explanation:
The main factors that caused the Reign of Terror were the political uncertainty, the threat of counter-revolution, and the radicalization of the Jacobins.
During the French Revolution, there was a lot of political turmoil and instability, with different factions vying for power. This led to fear and mistrust, which fueled the violence of the Reign of Terror.
The threat of counter-revolution was another significant factor. The Jacobins, who were the ruling party at the time, saw anyone who opposed them as potential enemies. They used the guillotine to eliminate perceived threats to the revolution.
