Why did many French Catholics reject the Edict of January?

The Edict of January 1562, issued by Catherine de’ Medici in an attempt to achieve religious reconciliation, granted Calvinists a degree of legal toleration and licensed coexistence.12

Many French Catholics rejected the edict because they viewed these concessions as a dangerous sign of favor toward the Protestant minority. This opposition was driven by devout Catholics who found leadership in the noble house of Guise, which positioned itself as the champion of Roman Catholicism in France.132

For these extremists, the edict was unacceptable because it provided legal protections to a group they considered heretical. This fundamental disagreement over religious policy and the crown's authority to grant such rights became a primary catalyst for the outbreak of the French Wars of Religion in 1562, beginning with the Massacre of Vassy.12
