Book excerpt: Mobility and Migration in Ancient Mesoamerican Cities is the first focused book-length discussion of migration in central Mexico, west Mexico and the Maya region, presenting case studies on population movement in and among Classic, Epiclassic, and Postclassic Mesoamerican societies and polities within the framework of urbanization and de-urbanization. Looking beyond the conceptual dichotomy of sedentism versus mobility, the contributors show that mobility and migration reveal a great deal about the formation, development, and decline of town- and city-based societies in the ancient world. In a series of data-rich chapters that address specific evidence for movement in their respective study areas, an international group of scholars assesses mobility through the isotopic and demographic analysis of human remains, stratigraphic identification of gaps in occupation, and local intensification of water capture in the Maya lowlands. Others examine migration through the integration of historic and archaeological evidence in Michoacán and Yucatán and by registering how daily life changed in response to the influx of new people in the Basin of Mexico. Offering a range of critical insights into the vital and under-studied role that mobility and migration played in complex agrarian societies, Mobility and Migration in Ancient Mesoamerican Cities will be of value to Mesoamericanist archaeologists, ethnohistorians, and bioarchaeologists and to any scholars working on complex societies.
