The concept of coalescent communities has been widely used by North American archaeologists as a framework for understanding cultural responses to social upheaval. In this article we explore how the concept of coalescence helps us understand the processes that led to the emergence of aggregated settlements in the Albuquerque district of the central Rio Grande Valley around the turn of the fourteenth century. We argue that such communities emerged as strategic local responses to disruptive social and demographic trends on a macroregional scale. Specifically, we use NAA and petrographic sourcing of Western Pueblo- and Rio Grande-style glaze-painted pottery in conjunction with settlement data from the site of Tijeras Pueblo (LA581) to explore how the amalgamation of immigrant and autochthonous people, technology, knowledge, and ritual creatively and radically transformed local and regional practices of community and identity formation.
