I assess economic changes on three dimensions: foreign trade, local craft production, and household wealth. Trade is evaluated for obsidian and ceramics (INAA, petrography, type classification) and local crafting is evaluated for ceramic, lithic, textile, and molded ceramic items. Wealth is measured using all excavated artifacts, with the relative values of artifact classes based on Colonial Nahuatl wills. Prior to Aztec rule, trade was increasing and diversifying, but craft production was low. Under Aztec rule, trade reoriented toward the Basin of Mexico, craft production remained low, and household wealth stabilized. Pre-Aztec inter-household variation for all dimensions is low, before increasing during the Yata phase.
Cultural changes are evaluated for ritual activities and foodways. I evaluate the degree of interhousehold variability, the overall similarity to other parts of Central Mexico, the degree of change under Aztec rule, and immigration versus emulation as potential explanations for that change. Evaluation is based on the distinction between high and low visibility objects and practices. The Dongu and Ninupi phase households at Calixtlahuaca were culturally homogeneous and regionally distinctive. During the Yata phase, the site became moderately more Aztec, but this change was unevenly distributed among households.
Together, the economic and cultural patterns at Calixtlahuaca indicate that the pre-Aztec local organization of power was relatively collective, but that this was partially overlaid by relatively indirect and non-collective Aztec imperial rule, with mildly negative effects.
The Central Highland capital of Teotihuacan had variable influence throughout Mesoamerica. One pronounced occurrence of this influence has been identified at Matacapan, which displays strong material culture and architectural connections to Teotihuacan. This research therefore employs a modified world-systems framework which removes the assumption of hierarchy and instead focuses on regional interaction within the periphery. It views the establishment of regional distribution networks centered at Matacapan that articulate with the two neighboring polities as a form of incorporation, the process wherein external groups are brought into a system.
To assess incorporation, four potential Matacapan-centered networks are analyzed. These networks consist of the distribution of two ceramic types and obsidian blades produced from two sources. Artifacts from survey, surface collection, and excavation were subjected to ceramic analysis, lithic analysis, petrography, neutron activation analysis, and X-ray fluorescence analysis to identify source, form, and production technology. These data aid in determining network participation in each polity. By assessing importation in these local polities, the form and degree of their incorporation will be identified.
Incorporation of indigenous polities into regional networks was not uniform within the Western Tuxtlas Region. Two Matacapan-centered networks were identified, and they differ in form and extent. One indigenous polity, Teotepec, participated in both networks while the other, Totocapan, participated in one. I argue that Teotepec’s incorporation into a second network was strategic in that it was mutually beneficial to both involved parties. Additionally, indigenous Tuxtlas’ polities were able to negotiate interaction with their Teotihuacan-affiliated neighbor for desired goods without forfeiting political or cultural autonomy.
I then test the practical application of this methodology by applying it to a mortuary sample including individuals from distinctive socioeconomic groups from the pre-Hispanic city of Teotihuacan, Mexico. The study recovers and uses the dietary isotope ratios within bone and tooth samples from 81 individuals buried throughout the city 1) to define the dietary correlates of wealth and status at Teotihuacan and 2) to identify individuals displaying lifetime dietary changes consistent with changes in socioeconomic status. In addition to supplementing our current understanding of Teotihuacan foodways and processes of geographic migration into the city, I identify an adult male individual from the La Ventilla B apartment compound who displays dietary changes throughout his life that are consistent with downward socioeconomic mobility from a high status socioeconomic group in early adolescence to an intermediate status group later in adulthood. I conclude by identifying ways to move forward with the comparative archaeology of socioeconomic mobility in premodern contexts and highlight the applicability of archaeological information to our understanding of present-day processes of social mobility.
Medieval European urbanization presents a line of continuity between earlier cities and modern European urban systems. Yet, many of the spatial, political and economic features of medieval European cities were particular to the Middle Ages, and subsequently changed over the Early Modern Period and Industrial Revolution. There is a long tradition of demographic studies estimating the population sizes of medieval European cities, and comparative analyses of these data have shed much light on the long-term evolution of urban systems. However, the next step—to systematically relate the population size of these cities to their spatial and socioeconomic characteristics—has seldom been taken. This raises a series of interesting questions, as both modern and ancient cities have been observed to obey area-population relationships predicted by settlement scaling theory.
To address these questions, we analyze a new dataset for the settled area and population of 173 European cities from the early fourteenth century to determine the relationship between population and settled area. To interpret this data, we develop two related models that lead to differing predictions regarding the quantitative form of the population-area relationship, depending on the level of social mixing present in these cities. Our empirical estimates of model parameters show a strong densification of cities with city population size, consistent with patterns in contemporary cities. Although social life in medieval Europe was orchestrated by hierarchical institutions (e.g., guilds, church, municipal organizations), our results show no statistically significant influence of these institutions on agglomeration effects. The similarities between the empirical patterns of settlement relating area to population observed here support the hypothesis that cities throughout history share common principles of organization that self-consistently relate their socioeconomic networks to structured urban spaces.
During WWII Japanese Americans were forcibly removed from their homes on the West Coast to ten incarceration centers, disrupting existing communities and forcing the formation of new ones. Amache is one of ten incarceration centers which housed families and individuals. The site resembled an urban center with public facilities and residential areas that functioned as neighborhoods. Archival and archaeological data indicate that residents developed socially defined neighborhoods. Internees modified each neighborhood through the creation of landscape features and development of social activity which provided a venue for residents to interact and form a sense of community identity.
Neighborhood residents clustered based on their affiliation to previous communities both in California and in the temporary detention centers. Clustering in demographically similar neighborhoods facilitated the development of new social interactions and led to the proliferation of landscape features and social events seen in the archaeological and archival record. I identify patterns of neighborhood interaction through an examination of the archaeological record and social network analysis using archival newspapers. Applying archaeological data in partnership with social network data illustrates the range of strategies used by incarcerees to create new communities and problematizes working with a single data source when attempting to identify socially defined neighborhoods.
