Out of this Colloquy of Poissy came the edict of January 17th, 1562, which provided that Protestants were to surrender all the churches and ecclesiastical buildings they had seized, and prohibited them from meeting for public worship, whether within a building or not, inside the walls of any town. On the other hand, they were to have the right to assemble for public worship anywhere outside walled towns, and meetings in private houses within the walls were not prohibited. Thus the Protestants of France secured legal recognition for the first time, and enjoyed the right to worship according to their conscience. They were not satisfied--they could scarcely be, so long as they were kept outside the walls; but their leaders insisted on their accepting the edict as a reasonable compromise. "If the liberty promised us in the edict lasts," Calvin wrote, "the Papacy will fall to the ground of itself." Within one year the Huguenots of France found themselves freed from persecution, and in the enjoyment of a measured liberty of public worship. It can scarcely be doubted that they owed this to Catherine de' Medici. She was a child of the Renaissance, and was naturally on the side of free thought; and she was, besides, at this time persuaded that the Huguenots had the future on their side. In the coming struggle they regarded this edict as their charter, and frequently demanded its restitution and enforcement. Catherine de' Medici had shown both courage and constancy in her attempts at conciliation. To the remonstrances of Philip of Spain she had replied that she meant to be master in her own house; and when the Constable de Montmorency had threatened to leave the Court, he had been told that he might do as he pleased. But she was soon to be convinced that she had overestimated the strength of the Protestants, and that she could never count on the consistent support of their nominal leader, the vain and vacillating Antoine de Bourbon. Had Jeanne d'Albret been in her husband's place, things might have been different. The edict of January 17th, 1562, had exasperated the Romanists without satisfying the mass of the Protestants. The marked increase in the numbers of Protestant congregations, and their not very strict observance of the limitations of the edict, had given rise to disturbances in many parts of the country. Everything seemed to tend towards civil war. The spark which kindled the conflagration was the Massacre of Vassy.[217] § 12. _The Massacre of Vassy._
