This chapter traces the consequences of Copán’s dynastic collapse for the realms that had been colonies or allies of the lowland Maya capital. All of these domains underwent demographic declines and political fragmentation. The nature of the changes, however, differed depending in part on what relations an area’s inhabitants had enjoyed with Copán’s agents. A crucial event in this process was the secession of Quirigua from the colonial network in CE 738. This dramatic development precipitated changes in governance at Copán even as it offered novel opportunities for former allies to advance claims to power that had not been available to them when Copán’s rulers enjoyed greater regional predominance. Ultimately, however, processes of political centralization and hierarchy building were curtailed among all participants in this network by CE 1000.
