Philippe-Antoine Merlin, known as Merlin de Douai was a French politician and lawyer.

The Mountain was a political group during the French Revolution. Its members, called the Montagnards, sat on the highest benches in the National Convention. The term, first used during a session of the Legislative Assembly, came into general use in 1793. By the summer of 1793, that pair of opposed minority groups divided the National Convention. That year, the Montagnards were influential in what is commonly known as the Reign of Terror.
