A number of recent studies1 suggest that prostitution – ‘The act or practice of indulging in promiscuous sexual relations, especially for money’2 – in western society increased dramatically in the late nineteenth century, both in real terms and in popular consciousness. ‘Large scale, conspicuous prostitution’, they argue, ‘was a by-product of the first, explosive stage in the growth of the modern, industrial city…’ It is a proposition of this article that such changes were, in fact, far more widespread. From the evidence of Guatemala it appears that prostitution also increased during these years in agricultural export societies. Under the impact of demands from industrializing nations, colonial and neo-colonial regimes overhauled domestic economic and social structures to increase raw material and food production for export. Unprecedented but unstable economic prosperity, urbanization, and the social disorganization resulting from the implementation of systems of forced labour and removal from the land created a climate propitious for an increase in and institutionalization of commerical sex. This paper is an examination of the growth of female prostitution in late nineteenth-century Guatemala City, of the situation and attitudes of the women involved, and of state efforts to control the traffic. More broadly, it argues that attempts to regulate prostitution must be understood as part of a liberal drive to mobilize and control society as a whole in the interest of a class-defined vision of national development.
