Prologue

This book revisits one of the great problems in Mayan archeology - the apparent collapse of Classic Maya civilisation from roughly AD830-950. During this period the Maya abandoned their power centres in the southern lowlands and rather abruptly ceased the distinctive cultural practices that marked their apogee in the Classic period. Archaeological fieldwork during the past three decades, however, has uncovered enormous regional variability in the ways the Maya experienced the shift from Classic to Post-classic society, revealing a period of cultural change more complex than acknowledged by traditional models. Featuring an impressive roster of scholars, the book presents the most recent data and interpretations pertaining to this perplexing period of cultural transformation in the Maya lowlands. Although the research reveals clear interregional patterns, the contributors resist a single overarching explanation. Rather, this volume's diverse and nuanced interpretations provide a new, more properly grounded beginning for continued debate on the nature of lowland Terminal Classic Maya civilisation.

This article reviews archaeological evidence on the development of Maya civilization in the southern lowlands. The evolution of sociopolitical complexity in the southern Maya lowlands is much discussed but as yet is incompletely resolved. Considerations are hampered by the fact that most early archaeological materials lie deeply buried beneath later human construction activity, making it difficult to locate remains that are directly relevant to questions bearing on the rise of complexity. Even should such remains be located, the overlying constructions usually make a real exposure of the earlier materials difficult. Nevertheless, sufficient evidence exists to posit a trajectory of complexity developing from Preclassic villages to Early Classic states to Late Classic attempts at creating hegemonic empires.

Palynology provides a record of past environmental change in the Maya Lowlands. The underlying principles are simple, but, as with all proxies, there are limitations. During the late glacial period, environmental change was governed by climate, which was cooler and much drier and supported sparse temperate vegetation. The early Holocene epoch was warmer and very wet in the southern Lowlands when mesic tropical forests predominated, while the northern Yucatan Peninsula was edaphically dry until eustatic sea level rose. The modern distributions of plant associations and climatic gradients were established at the end of the early Holocene. Climatic variability continued throughout the Holocene. However, the ability of palynology to identify climatic events is hindered after the Maya became numerous in the Lowlands. Then, multidisciplinary studies provide a better interpretation of events, especially during the late Holocene. Pollen records poorly reflect cyclical droughts seen in isotopic records, as natural vegetation has adapted to these fluctuations.
