France invades Algeria
France invaded Algeria in 1830, annexing the coastal Mediterranean provinces in 1834. This conquest brought with it attention to prostitution in the colony. Although Parent-Duchatelet's first edition hardly mentioned the Maghreb, the editors of the second (1857) edition included a report in On Prostitution in the City of Paris from Doctor Alphonse Bertherand, chief doctor of the French Army, describing prostitution at the time of conquest.

This document is interesting for its contradictions. It contains sweeping generalizations about the women of the East, yet makes important distinctions among tribal groups and urban Algerians. It describes Algerian women as slaves of Islamic custom who yet trade sex freely. And it imposes a curious form of what we might call "gender washing," depicting the treatment of Algerian women as a justification for French colonization, as if France in 1857 was some sort of paradise of gender egalitarianism and women's agency.
