Three visions of anthropology collided in San Cristóbal de las Casas, Chiapas in the 1950s. Infrastructural improvements, indigenista politics, and increased US social science funding intensified research on Indigenous Chiapas. The scene drew together imperial travelers, modernist ethnographers, and Mexican development administrators. Among them was Danish explorer-archaeologist Frans Blom, who struggled to establish his estate as a reputationally redeeming fieldwork institute. This article parses how some modernist anthropologists distanced themselves from Blom’s imperial legacy, while others pressed his ideas of cultural continuity into implicit, controversial claims for their centrality to ancient and modern Maya studies writ large.
