What legal decree recognized Catholicism as the official religion of France while granting rights to the Huguenots?

The Edict of Nantes is the legal decree that recognized Catholicism as the official religion of France while simultaneously granting significant rights and protections to the Huguenots, who were French Protestants. Issued in 1598 by King Henry IV, this edict aimed to bring an end to the violent conflicts between Catholics and Protestants during the Wars of Religion in France. It established a framework for civil peace by allowing Huguenots to practice their religion freely in certain designated areas and provided them with political rights, including the right to hold public office and maintain fortified towns.

The other choices represent different historical documents or decrees that address various rights and issues but do not pertain to the specific recognition of Catholicism and the rights of Huguenots. The Declaration of the Rights of Man focuses on individual rights and liberties post-French Revolution, the Edict of Toleration refers to later religious toleration efforts, and the Constitution of 1791 established a constitutional monarchy but did not address the same religious freedoms as the Edict of Nantes.
