The last 20 years have seen growing attention in Scandinavian archaeology towards the study of the Iron Age household. The aim of this paper is to challenge the conceptions of what the household is and argue for the potential in approaching households as heterogenous, emergent assemblages, with an untapped potential in diachronic and spatial studies. Inherent in the vast archaeological record of the Scandinavian Iron Age is a capacity for broader perspectives to explore household processes’ duration and change. Drawing on theoretical insights from the Communities of Practice (COP) framework and assemblage-based thinking, the paper accentuates the household as a key arena for learning, knowledge and identity formation and a heterogeneous unit bound up in changing spheres of interaction. Household practices, or the shared repertoire of households, represent analytical mechanisms that allow for the study of variation, continuity and recalibration, thus providing essential entry points to studies of social processes.
