Neuchâtel adopted the Reformation in 1530. What impact did this decision by the citizens of the city have on the population? This book describes the disci-pline that has since surrounded the parishioners of the canton of Neuchâtel and the lordship of Valangin and evoked three centuries of Neuchâtel consis-tories. Based on the analysis of thousands of cases, it draws back the cur-tain on daily life, love, the revolts of a small population, mostly rural, in which the sources speak only rarely.
