What edict announced a policy of toleration to all religions?

The Edict of Nantes, issued in 1598 by King Henry IV of France, announced a policy of toleration to all religions, particularly granting significant rights to the Huguenots (French Protestants). This edict aimed to bring an end to the Religious Wars in France and established a framework for coexistence between Catholics and Protestants. It allowed Huguenots to practice their religion freely and maintain fortified towns, though it was later revoked in 1685 by Louis XIV, leading to renewed persecution.
