What rights did the Edict of January of 1562 give to French Calvinists?

The Edict of January 1562, issued by Catherine de’ Medici during her regency for Charles IX, was a significant attempt to achieve religious reconciliation in France following the failure of the Colloquy of Poissy.12

This decree granted French Calvinists, or Huguenots, the right of licensed coexistence with specific legal safeguards. By providing this degree of toleration, the edict established a legal framework for the Huguenots to practice their faith, which they accepted, though it was strongly rejected by devout Catholics.12

Because the crown could protect its Protestant subjects in law but struggled to defend them against the violent opposition of Catholic extremists—led by the house of Guise—the edict failed to prevent the outbreak of the first Wars of Religion in 1562.132
