Subcommunal bastardy and regional religion: Micro and macro aspects of the debate on the sexual revolution

Birth reports throughout Europe and North America register low ratios of bastardy (5 percent or less) in premodern times and much higher ratios after 1750. Historians have difficulty explaining such a sudden turn about in an area of basic human behavior. By studying bastardy ratios at the settlement rather than communal (parish) level, I show that some premodern people did support a high incidence of illegitimacy. The turn‐about‐face in sexual matters was not as abrupt or as total as we have imagined.

This discovery does not impugn the accuracy of the baptismal register as an index to sexual conduct of the populace at large. The problem of explaining sexual restraint in premodern times remains. Historians have frequently posited religion as the controlling factor that moderated the sexual behavior of the masses. There are problems with this explanation and I suggest that it is only efficacious when it can be demonstrated at the subcommunal or settlement level.
