Drawing on a case study from the Maya site of Actuncan, Belize, this article presents collective remembering as a way to conceptualize the relational construction of memory by ancient societies. Emphasizing the process of remembering allows archaeologists to investigate how memory divides as well as unites. Over time, the interactions between humans and between humans and their landscape that take place as part of everyday life produce memories of the past that are inaccurate and inconsistent between individuals. In particular, people who interact frequently, either due to geographic proximity or similarity in socioeconomic status, tend to form mnemonic communities—communities based on a similar understanding of the past—that may serve as identity markers differentiating them from other groups. At Actuncan, the community’s past was collectively remembered across times of prosperity and subjugation. First, the site was a Late and Terminal Preclassic seat of an early divine king who built a monumental ceremonial center. Second, when the site was subjugated during the Early and Late Classic periods, the ceremonial center fell out of use, but the site’s commoner households remained continuously occupied. Finally, in the Terminal Classic period, the site’s residents reestablished Actuncan as a local seat of authority following the Classic Maya collapse. The community’s use of the Preclassic monumental core during the Terminal Classic period indicates that the memory of the site’s Preclassic apogee served to legitimize their Terminal Classic authority. However, the Preclassic past was remembered in a manner consistent with contemporaneous cultural forms and the site’s recent past of subjugation.
