Despite recent emphasis on the impact of nationalism on archaeology, the discussion has centered more on the ideological framework of the culture-historical school of archaeology, particularly on the concept of archaeological culture. Comparatively little attention has been paid to how archaeologists contributed to the construction of the national past. This article examines Slavic archaeology, a discipline crisscrossing national divisions of archaeological schools, within the broader context of the ‘politics of culture’ which characterizes all nation-states, as ‘imagined communities’ (Anderson 1991). Indeed, the current academic discourse about the early Slavs in Ukraine, Russia, and Romania appears as strikingly tied to political, rather than intellectual, considerations. In eastern Europe, the concept of archaeological culture is still defined in monothetic terms on the basis of the presence or absence of a list of traits or types derived from typical sites or intuitively considered to be representative cultural attributes. Archaeologists thus regarded archaeological cultures as actors on the historical stage, playing the role individuals or groups have in documentary history. Archaeological cultures became ethnic groups, and were used to legitimize claims of modern nation-states to territory and influence.
