Abstract:The intensification of fieldwork in northern Mesopotamia, the upper region of the TigrisEuphrates basin, has revealed two cycles of expansion and reduction in social complexity between 4400-2000 BC. These cycles include developments in social inequality, political centralization, craft production and economic specialization, agropastoral land use, and urbanization. Contrary to earlier assessments, many of these developments proceeded independently from the polities in southern Mesopotamia, although not in isolation. This review considers recent data from excavations and surveys in northern Iraq, northeastern Syria, and southeastern Turkey with particular attention to how they are used to construct models of early urban polities.Key words: Mesopotamia, complex society, urbanism, collapse 1
IntroductionOver a span of more than two millennia, northern Mesopotamia witnessed the emergence of urban complex society, its collapse and rebirth, and a further episode of collapse. This time span (ca. 4400-2000 BC) has been intensively studied by archaeologists over the last two decades, largely because of twin push (the closure of Iraq to foreign archaeology) and pull (salvage campaigns in advance of dam projects) forces. As a result, what was once considered to be the periphery of early urbanism and state formation in southern Mesopotamia (modern southern Iraq) has emerged as a region of interest in its own right. In many ways we now have a superior understanding of major social developments in the north (e.g., urbanism, craft production, agricultural and pastoral organization, the development of the landscape) than we do for the south, and improvements in chronology have revealed that many aspects of social complexity that were once assumed to have been imported from southern Mesopotamia have earlier and entirely indigenous origins.This review describes the development of social complexity from 4400 BC to the collapse of urban society at the end of the 3rd millennium BC in northern (or upper) Mesopotamia, defined here as the Tigris and Euphrates River valleys and the plains and steppe between them that fall today in northern Iraq, northern Syria, and southeastern Turkey (Fig. 1).Much archaeological research in the region, and in the Near East in general, adopts a culture historical approach that emphasizes typology and the development of sequences of material culture; here the emphasis is on anthropologically oriented research published since 1990.Geographically, the focus is on the river valleys and alluvial plains of Syria, and particularly the Upper Khabur basin of Hassake province. Occasionally I refer to sites beyond northern Mesopotamia proper when they are relevant to the discussion, particularly the western Syrian 2 cities of Ebla and Umm al-Marra; the important Syrian city of Mari, on the Euphrates near the Iraqi border, is largely southern Mesopotamian in orientation and will be not be discussed (although see Margueron 2004).In Mesopotamian archaeology generally, social complexity is described throug...
