Explanation:

The Edict of Nantes was an official document signed in 1598 in France by the king of that time King Henry IV with the main purpose of guaranteeing the rights to the Calvinists Protestant population, also called the Huguenots considering before this document was signed only the Catholic population had civil rights as this was the official religion of the nation, while population from other religions were considered as heretics and therefore were not protected by the government. Because of this, this document was an important step towards religious tolerance and the protection of all the population by the government as it allowed people in France to follow a different religion to the official and still have civil rights. Thus, the Edict of Nantes states that "Catholicism was to be the official religion in France but Protestants could worship freely" as this document meant the Protestant population could worship freely and being protected by the government despite they were not part of the official religion.
