Foreign archaeologists working in the Maya region collaborated with the United Fruit Company during the first half of the twentieth century. In Guatemala, the Company funded research projects in Quiriguá (1910–1915) and Zaculeu (1946–1949). These collaborations supported the broad objectives of U.S. imperialism in the region, but comparing the projects suggests the fact of collaboration did not determine how they operated in the field. Drawing on theories of racialization, I suggest that the Company functioned as a conduit through which broader political economies of race and labor conditioned the practice of archaeology. In Quiriguá, archaeologists’ reliance on United Fruit’s administrative mechanisms led to the reproduction of the Company’s notorious labor practices and the exploitation of Afrodescendant labor in the context of a field site. In Zaculeu, a comparable dependence resulted in scientific methods being used to demonstrate Indigenous deficiency and racial continuity in the service of Company public relations and tourism development objectives. Despite wide-ranging changes in archaeological practice and governmental policy, comparing the cases illustrates how the operations of a corporate firm tied a field science into broader political economies of racialized labor. In so doing, I seek to shift analytical attention from the circulation of ideas about the past to the context of archaeological fieldwork, in which relationships of exploitation were renewed—and in which they might be contested today.
