Geographies of sexuality have paid minimal attention to interracial relatio
ns. To rectify this, we examine the genealogy of the criminalization and pu
nishment of "interracial" relations. Drawing on three historical moments in
the evolution of race relations in Anglo-America, we argue that the crimin
alization of these relations has historically been grounded in material rel
ations and not in abstract ideals of racial purity or fears of racial degen
eration. Using a strategy of "unnatural discourse," we suggest that as the
American capitalist system expanded, the punishment of multiracialized sexu
al relations has generated and retained important ideological functions tha
t have never been far removed from their material base.
