'The purity of the blood': Poncet de la Grave,pronatalism and empire

This article will analyze key publications of Guillaume Poncet de la Grave (1725-1803), formerly the monarchy’s representative to the Admiralty Court, who worked during the Ancien Régime to restrict immigration to France, particularly that of people of color. He was also a passionate advocate for French imperial expansion. After the Revolution, in his political tract Réflections on the Unmarried, he expressed his anxiety over a declining French birthrate and a desire to have the state monitor marriage, sexuality, and reproduction in order to increase legitimate births. In this work he identified threats to what he referred to as ‘the purity of the blood’ within and without France, and proposed to the Republic legislation designed to eliminate them. Poncet de la Grave’s career has been largely neglected but his former position merits a closer look at his political writing, which expressed significant, constant objectives that demonstrate thematic continuity over a tumultuous time. French fears of depopulation and national ‘degeneration’ were still strong at the turn of the century, and remain of great interest to historians eager to understand how they were discussed in the context of great historical change.
