1) In the late 18th century, France declared itself a republic but soon descended into turmoil due to military setbacks, factionalism in government, and counterrevolutionary uprisings.
2) To combat these threats, the radical Jacobin faction known as "The Mountain" seized control of the government and instituted a period of violent repression known as "The Terror" from 1793-1794.
3) Though initially successful at eliminating opposition, The Terror grew increasingly violent and unstable, leading to the overthrow and execution of its leader Maximilien Robespierre in 1794 and the eventual establishment of a new constitutional government.
