The Mountain (French: La Montagne) was a political group during the French Revolution whose members, called Montagnards, sat on the highest benches in the Assembly. They were the most radical group and opposed the Girondists. The term, which was first used during a session of the Legislative Assembly, came into general use in 1793. Led by Maximilien Robespierre, the Montagnards unleashed the Reign of Terror in 1794.
