The Edict of Amboise, also known as the Edict of Pacification, was signed at the Château of Amboise on 19 March 1563 by Catherine de' Medici, acting as regent for her son Charles IX of France. The treaty officially ended the first of the French Wars of Religion, inaugurating a period of official peace in France by guaranteeing the Huguenots religious privileges and freedoms. This peace would be broken in 1567 by the renewal of religious hostilities.
