Across contexts as disparate as the United States, Australia, China, Japan, India, Russia, Spain and Europe more broadly, concepts of national identity are deeply intertwined with racial “purity” (Segal 1991; Weiner 1995; Dikötter 1997; Ang and Stratton 1998; Collins 1998; Tolz 2007; Goode 2009; Ghoshal 2021). Scientific rhetoric and technologies, from phrenology to genetics, have often been co-opted into shoring up myths about homogeneity and purity, and archaeology is no exception (Díaz-Andreu 1995; Epperson 1997; Arnold 2006; Challis 2013; Hakenbeck 2019; Pai 2020). What Rafi Greenberg and Yannis Hamilakis add to this discussion with their book Archaeology, Nation, and Race (2022) is a deep consideration of the myriad ways in which the metaphor of purification shows up throughout archaeological practice. Their discussion invites a consideration of what it is about archaeology in particular that lends it to arguments about the salience of nationalist racial categories and homogeneity.
