At the conclusion of the conflict in 1598, the Protestant Henry of Navarre, heir to the French throne, converted to Catholicism and was crowned Henry IV of France. He issued the Edict of Nantes, which granted Huguenots substantial rights and freedoms. His conversion did not end Catholic hostility towards protestants or towards him personally, and he was eventually murdered by a Catholic extremist. The wars of religion threatened the authority of the monarchy, already fragile under the rule of Catherine's three sons and the last Valois kings: Francis II, Charles IX, and Henry III. This changed under the reign of their Bourbon successor Henry IV. The edict of Nantes was revoked later in 1685 with the Edict of Fontainebleau by Louis XIV of France. Henry IV's wise governance and selection of able administrators did leave a legacy of a strong centralized government, stability, and economic prosperity that has gained him the reputation as France's best and most beloved monarch, earning him the designation "Good King Henry".
