safe havens (places de sûreté), which were military strongholds such as La Rochelle, in support of which the king paid 180,000 écus a year, along with a further 150 emergency forts (places de refuge), to be maintained at the Huguenots' own expense. Such an act of toleration was unusual in Western Europe, where standard practice forced subjects to follow the religion of their ruler — the application of the principle of cuius regio, eius religio.

While it granted certain privileges to Huguenots, the edict reaffirmed Catholicism as the established religion of France. Protestants gained no exemption from paying the tithe and had to respect Catholic holidays and restrictions regarding marriage. The authorities limited Protestant freedom of worship to specified geographic areas. The Edict dealt only with Protestant and Catholic coexistence; it made no mention of Jews, or of Muslims, who were offered temporary asylum in France when the Moriscos were being expelled from Spain.
