THE CHRONOLOGY OF MAYAPAN : New Radiocarbon Evidence

Thirty-eight radiocarbon dates from Mayapan provide new information about the Postclassic chronology of this city. We analyze ceramic frequencies associated with our radiocarbon samples and discuss temporally diagnostic types in the Mayapan sequence. Radiocarbon samples from early construction contexts suggest that the Postclassic center was founded by at least the twelfth century, or possibly the eleventh century a.d. on a modest scale. Additional dates help to assign much of the city's later architecture to the thirteenth and fourteenth centuries a.d., and provide hints of violence, conflict, and abandonment events prior to the final collapse. Our results imply that Mayapan may have begun as a small center while Chichen Itza waned from its dominant political position on the peninsula, and that the establishment of Mayapan as a major regional capital may have been a process that took a century or longer to complete.
