The history of the Protestant Reformed churches in France in the century following the Wars of Religion, their trials and sufferings, is well documented. It is a tragic page in modern European history and retains the attention of commentators because rarely has a people group been persecuted so intensely for so long, to the point of virtual extinction. Less known, perhaps because of the linguistic barriers, is the development of church life and the theological struggles in the Protestant churches during that period. Recent publications contribute to rectify this lack. The present article is an introduction to some of the issues of the time which have perennial interest.
