The Treaty of Nemours abolishes tolerance to Protestants in France.

Articles of the Treaty of Nemours (or Treaty of Saint-Maur) were agreed upon in writing and signed in Nemours on 7 July 1585 between the Queen Mother, Catherine de' Medici, acting for the King, and representatives of the House of Guise, including the Duke of Lorraine. Catherine hastened to Saint-Maur-des-Fossés, where on 13 July the treaty was signed between King Henry III of France and the leaders of the Catholic League, including Henri, duc de Guise. The king was pressured by members of the Catholic League to sign the accord which was recognized by contemporaries as a renewal of the old French Wars of Religion.
