Throughout the Guianas, people of all ethnicities fear one particular kind of demonic spirit. Called baccoo in Guyana, bakru in coastal Suriname, and bakulu or bakuu among Saamaka and Ndyuka Maroons in the interior, these demons offer personal wealth in exchange for human life. Based on multisited ethnography in Guyana and Suriname, this paper analyzes converging and diverging conceptions of the “same” spirit among several Afro- and Indo-Guianese populations. We argue that transformations in how people conceptualize bakulu reveal how supposedly radical moral differences are constructed within and between populations in the multi-ethnic Caribbean. More than figurative projections of monetized inequality or racial and ethnic prejudices, baccoo actively mediate how people throughout the Guianas think about and experience the everyday conduct of economic and racial relations.
