This essay is concerned with the construction of colonial categories and national identities and with those people who ambiguously straddled, crossed, and threatened these imperial divides.1 It begins with a story about métissage (interracial unions) and the sorts of progeny to which it gave rise (referred to as métis, mixed bloods) in French Indochina at the turn of the century. It is a story with multiple versions about people whose cultural sensibilities, physical being, and political sentiments called into question the distinctions of difference which maintained the neat boundaries of colonial rule. Its plot and resolution defy the treatment of European nationalist impulses and colonial racist policies as discrete projects, since here it was in the conflation of racial category, sexual morality, cultural competence and national identity that the case was contested and politically charged. In a broader sense, it allows me to address one of the tensions of empire which this essay only begins to sketch: the relationship between the discourses of inclusion, humanitarianism, and equality which informed liberal policy at the turn of the century in colonial Southeast Asia and the exclusionary, discriminatory practices which were reactive to, coexistent with, and perhaps inherent in liberalism itself.2
