The Treaty of Nemours abolishes tolerance to Protestants in France.

The Treaty of Nemours were articles that 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.

Protestantism is a branch of Christianity that emphasizes justification of sinners through faith alone, the teaching that salvation comes by unmerited divine grace, the priesthood of all believers, and the Bible as the sole infallible source of authority for Christian faith and practice. The five solae summarize the basic theological beliefs of mainstream Protestantism.
