The sixteen synodal provinces (1660)

Since 1620, when the Béarn region lost its independence, the Reformed Churches of the French kingdom had been organised into a framework of 16 provinces.

Based on the frontiers of 1620, each province was listed with its number of churches and the estimated number of its Reformed population around 1660. The only exceptions were Sedan, Metz, Alsace and the region Montbéliard.
