Généalogie d’un problème public. La consanguinité et la promotion d’une régulation institutionnelle des unions

Abstract : This article sheds new historical light on a series of scientific studies undertaken since the nineteenth century that contributed to the framing of “first cousin unions” as a public problem. The rise of heredity theories as an object of knowledge, at a time of increasing secularization of marriage, generated controversies over endogamy that spread to medicine, public hygiene, natural sciences, and later eugenics and the social sciences. A thorough examination of the investigations into the effects of endogamy in human populations, with special attention paid to the uses of evidence, allows for a detailed analysis of the shifting definition of consanguinity and the issues at stake. Yet, it simultaneously shows the persistence of a fiction around blood, as well shedding light on religious views on unions between relatives, both in the natural and the social sciences.
