While the recent application of the house model to archaeology (Joyce and Gillespie 2000 Beyond Kinship: Social and Material Reproduction in House Societies. University of Pennsylvania Press, Philadelphia) has renewed interest in the nature of Classic Maya social organization, the relationships between Classic Maya social units and Classic Maya polities remain poorly understood. This article examines the effects of the Classic Maya collapse of Copan, Honduras on its constituent social units in an effort to ascertain the flexibility and resilience of these groups within larger political structures. Previous researchers suggested that Copan's collapse was limited largely to the ruling elite. However, the Copan Postclassic Archaeological Project has documented a distinct, possibly foreign occupation in the site center from a.d. 950 to 1100. These data suggest that the longevity of all Classic Copaneco social groups in the wake of dynastic collapse was significantly shorter than some have postulated. These data demonstrate that Classic Maya social units were not semiautonomous groups but, instead, were integrated within polities. Thus, they must be understood within larger political frameworks.
