The French Quadrumvirate was a political organisation in France after the Autumn Revolutions of 1920, in which the Drumontian government was overthrown by a barricade-led revolution led by students and the ceasefire imposed by French soldiers in the Somme Theatre of the Great War. A four-member head of state was established, with a representative for the proletariat and the students (Laurént Enjolras), the political movements and the bourgeoisié (Jean Jaurés), the military (General Jean Baptiste Marchand) and the monarchists and the right (Philippe, duc d'Orleans). The purpose of the Quadrumvirate was stated to be:
- Restoration of the French democratic system after twenty-four years of dictatorship,
- Negotiation with the victorious Allied powers (the United Kingdom, Germany and Russia) in what would become the Treaty of Peterhof,
- Organisation of a stable transition towards democratic rule that pleases all the four represented sides of the Quadrumvirate, and
- Developing the destroyed regions of Metropolitan France and her Colonies after the war.
The French Quadrumvirate was extremely important for French history, establishing the system of multiple head of state that survives to this day, as well as being the restoration of democratic governance that would prevail in France until present day. While the temporary Quadrumvirate just lasted five years (and provisional government only seven), it is considered one of the most vital political periods of French history.
