Jacobin

The Society of the Friends of the Constitution (French:Société des amis de la Constitution), after 1792 re-named Society of the Jacobins, Friends of Freedom and Equality (French:Société des Jacobins, amis de la liberté et de l'égalité), commonly known as the Jacobin Club (Club des Jacobins) or just collectively Jacobins (French: [ʒa.kɔ.bɛ̃ ], English /ˈdʒæ.kə.bɪnz/), was the most famous and influential political club in the development of the French Revolution. Initially founded by anti-Royalist deputies from Brittany, the Club grew into a nationwide republican movement, with a membership estimated at a half million or more. The Jacobin Club was heterogeneous and included both prominent parliamentary factions of the early 1790s, the radical Mountain and the more moderate Girondists.
