The Peace of Alais, also known as the Edict of Alès or the Edict of Grace, was a treaty negotiated by Cardinal Richelieu with Huguenot leaders and signed by King Louis XIII of France on 27 September 1629. It confirmed the basic principles of the Edict of Nantes, but differed in that it contained additional clauses, stating that the Huguenots no longer had political rights and further demanding they relinquish all cities and fortresses immediately. It ended the religious warring while granting the Huguenots amnesty and guaranteeing tolerance for the group. Unfortunately for the Huguenots, the Peace did not last permanently. Louis XIV resumed persecution of Protestants, culminating in a revocation of the Edict of Nantes in 1685.
