The Edict of Nantes, issued on 13 April 1598, by Henry IV of France, granted the Calvinist Protestants of France (also known as Huguenots) substantial rights in a nation still considered essentially Catholic. In the Edict, Henry aimed primarily to promote civil unity. The Edict offered many specific concessions to the Protestants, such as amnesty and the reinstatement of their civil rights, including the right to work in any field or for the State and to bring grievances directly to the king. It marked the end of the religious wars that had afflicted France during the second half of the 16th century.
