In light of new and expanding research, the contributors to this volume premise that the relationship of Classic to Postclassic in the Northern and Southern Maya Lowlands is much more complex than was traditionally thought. The essays offer a useful introduction to current thought regarding the development of Lowland Maya civilization after the collapse of the Classic Period in the South. The contributors hold diverse opinions, but work toward a restructuring of thinking on the Postclassic, and on directions for future research, with suggestions of specific sites, regions, periods and questions for study. The ideas presented here emphasize the long-overdue redress of domination of Maya studies by a Classic Period point of view.
