The archaeological sites of Mexico"s Yucatan peninsula, including Chichen Itza and Uxmal, are among the most visited ancient cities of the Americas. The past 20 years have seen a revolution in our interpretations of social and political process in the northern Maya lowlands, but the great advances made by archaeologists in our understanding of this half of the Maya region are under-represented in both scholarly and popular literature. The aim of this volume is to present the results of new and important archaeological, epigraphic, and art historical research in the Mexican states of Yucatan, Campeche, and Quintana Roo to a broad audience of scholars, students, and educated laymen who are interested in the ancient Maya. This volume consists of original and timely contributions of the sort often published in journals. The writing style of the volume, however, is intended to be lively and approachable so as to be accessible and of particular use to undergraduate and graduate students, as well as to more advanced scholars. The organization of the volume is temporal (from the Middle Preclassic to colonial and modern periods), so that readers will understand how new data and interpretations have changed the whole of our understanding of Maya history.
