Foodways in societies at every social scale are linked in complex ways to processes of social change. This dissertation explores the interrelationship between foodways and processes of rapid social transformation. Drawing on a wide range of archaeological and ethnographic data from the Cibola region, I examine the role of foodways in processes of population aggregation and community formation and address how changes in the scale and diversity of social life interacted with the scale and organization of food production and consumption practices. To address the interrelationships between foodways and social transformations, I employ a conceptual framework focused on two social dimensions of food: cuisine and commensality. This study comparatively examines cuisine and commensality through time by investigating a range of interrelated food activities including: food production, storage, preparation, cooking, consumption and discard.

While settlement patterns and other more obvious manifestations of aggregation have been studied frequently, by examining foodways during periods of aggregation and social reorganization this study provides new insights into the micro-scalar processes of social transformation, cuisine change, and economic intensification associated with increases in settlement size, density, and social diversity. I document how food production and preparation intensified in conjunction with increases in the size of settlements and the scale of communal commensal events. I argue that foodways were a critical aspect of the social work of establishing and maintaining large, dense communities in the 13th and 14th centuries. At the same time, widespread changes in commensal practices placed a larger burden on household surplus and labor and women were likely the most affected as maize flatbreads and other foods made with finely ground flour were adopted and became central to cuisine. As such, this study provides insights into how rapid social transformations in the late 13th and 14th centuries were experienced differently by individuals, particularly along gendered lines. Studies of foodways, and specifically the social dimensions of food, offer a promising and often underutilized source of information about past processes of population aggregation, social integration, and transformations in the political economies of small-scale societies the past.

Coalescence is a distinctive process of village aggregation that creates larger, socially cohesive communities from smaller, scattered villages. This dissertation asks: how do individual and collective social relationships change throughout the process of coalescence, and how might these relationships contribute to the social cohesiveness of a coalescent community?

Coalescent communities share characteristics that reveal the relationship between collective action and collective identities in their social dynamics. Collective identity is a shared sense of oneness among members of a group. It can be understood as the product of two processes: categorical and relational identification. Categorical identification is a shared association with a specific category, such as an ethnic group or a religious association. Relational identification is the product of direct, interpersonal interaction. The potential for a group to engage in collective action is linked to the intensity (prominence as compared to other aspects of identity) and scale (social unit and size of group) of categorical and relational identification.

Patterns in the intensity and scale of categorical and relational identification are used to trace changing social dynamics through the process of community coalescence. The case study is a sequence of four sites that were successively occupied by the same Ancestral Wendat (Iroquoian) community over a period of 150 years in south-central Ontario. The intensity of categorical identification is assessed by measuring the consistency of decorative styles among pottery vessels. The intensity of relational identification is assessed by measuring production variability among ceramic pots and pipes using microscopic characterization.

The analyses reveal a correlation between the intensity and scale of categorical and relational identification and village-scale social cohesion and collective action. Village-scale categorical identification was less intensive during the period of initial aggregation, with a subsequent increase in intensity observed at fully coalesced sites where evidence of social cohesion and village-scale collective action is present. As coalescence progressed, the intensity of relational identification at the village scale decreased. This evidence suggests that changing dynamics of categorical and relational ties among community members were intertwined with the development of social cohesion and the increased potential for village-scale collective action at the culmination of coalescence.

Mobility is an important aspect of the lives of religious individuals described by medieval texts in early and late medieval Ireland, and biogeochemical methods can be used to detect mobility in archaeological populations. Stories are recorded of monks and nuns traveling and founding monasteries across Ireland, Scotland, England, Wales, and other areas of Europe. However, these texts rarely address the quotidian lives of average monks and nuns who lived in monastic communities. This dissertation seeks to understand if travel was a typical part of the experiences of religious and lay people in early and late medieval Ireland. It also aims to increase understanding of how monastic communities related to the local lay communities, including addressing if the monastery was populated by those who grew up in the local area. Another methodological aim of this dissertation is to advance the field of archaeological biogeochemistry by (1) adding to the bioavailable strontium baseline in Ireland and (2) quantifying the contribution of ocean-derived strontium to coastal environments. These topics are explored through the biogeochemical analysis of 88 individuals buried at 5 early and late medieval monasteries in Ireland and the analysis of a total of 85 plant samples from four counties in Ireland. The three papers in this dissertation present: (1) a summary of the mobility of religious and lay people buried at the monasteries (Chapter 2), (2) a case study presenting evidence for fosterage of a local child at the early medieval monastery of Illaunloughan, Co. Kerry (Chapter 3), and (3) a study designed to quantify the impact of sea spray on bioavailable strontium in coastal environments (Chapter 4). The majority of lay and religious individuals studied were estimated to be local, indicating that medieval Irish Christianity was strongly rooted in the local community. The study of ocean-derived strontium in a coastal environment indicates that sea spray has a non-uniform impact on bioavailable strontium in coastal regions. These findings shed new light on medieval monastic and lay life in Ireland through the application of biogeochemical methods, contributing to the growth of the field of archaeological chemistry in Ireland.

This paper studies the change in social diversity and interaction space from the Classic to Postclassic periods in the Mimbres Valley and East Mimbres Area. Between the Classic and Postclassic periods the Mimbres region of the American Southwest exhibits an increase in diversity of ceramic wares. Previous research suggests that increased diversity of ceramics indicates a more diverse community, which could pose challenges to local social interaction (Nelson et al. 2011). I am interested in whether the architecture of plazas, focal points of communities' social structures, change in response to the growing social diversity. To examine this, I quantify the diversity of painted ceramics at Classic and Postclassic villages as well as the extent of the enclosure of plazas. I find that there is a definite shift towards greater plaza enclosure between the Classic and Postclassic periods. I conclude this paper with a discussion of possible interpretations of this trend regarding the social reactions of Mimbres communities to the changes which reshaped the region between the Classic and Postclassic periods.

This dissertation develops a multidimensional approach to examine the ways in which people in small-scale societies create, perpetuate, justify, and overcome social inequality. Inequality can exist within a number of independent domains, some of which are likely to be subtle and dissimilar from those familiar to Western society. The advantages and disadvantages of inequality can shift between various groups and across social scales. Recent ethnographic work suggest that the most common domain of inequality in small-scale societies may involve status accrued to founding lineages. This hypothesis is examined in relation to four additional domains, each inspired by ethnographic data from indigenous groups of the U.S. Southwest: differential access to productive resources, ritual knowledge and practice, nonlocal objects and styles, and material wealth. Analyses are carried out with data from seven archaeological sites in the Mimbres region of southwestern New Mexico, spanning a period from approximately 250 to 1130 C.E. Results show that inequality was present throughout the Mimbres archaeological sequence but that it shifted over time, across space and social scales, and varied in magnitude in non-directional ways. Results also identify persistent factionalism wherein groups vied for moral authority based on differences in residential antecedence and justified via religious differences. Insight from this research benefits the social sciences by developing a number of methodological approaches, particularly to the archaeological study of primacy and antecedence, by demonstrating the necessity of a nuanced, multi-faceted approach to inequality, and by revealing the complex and plastic nature of inequality.

This dissertation research examines neighborhood socio-spatial organization at Calixtlahuaca, a Postclassic (1100-1520 AD) urban center in highland Mesoamerica. Neighborhoods are small spatial units where residents interact at a face to face level in the process of daily activities. How were Calixtlahuaca's neighborhoods organized socio-spatially? Were they homogenous or did each neighborhood contain a mixture of different social and economic groups? Calixtlahuaca was a large Aztec-period city-state located in the frontier region between the Tarascan and Triple Alliance empires. As the capital of the Maltazinco polity, administrative, ritual, and economic activities were located here. Four languages, Matlazinca, Mazahua, Otomi, and Nahua, were spoken by the city's inhabitants. The combination of political geography and an unusual urban center provides an opportunity for examining complex neighborhood socio-spatial organization in a Mesoamerican setting. The evidence presented in this dissertation shows that Calixtlahuaca's neighborhoods were socially heterogeneous spaces were residents from multiple social groups and classes coexisted. This further suggests that the cross-cutting ties between neighborhood residents had more impact on influencing certain economic choices than close proximity in residential location. Market areas were the one way that the city was clearly divided spatially into two regions but consumer preferences within the confines of economic resources were similar in both regions. This research employs artifact collections recovered during the Calixtlahuaca Archaeological Project surface survey. The consumption practices of the residents of Calixtlahuaca are used to define membership into several social groups in order to determine the socio-spatial pattern of the city. Economic aspects of city life are examined through the identification of separate market areas that relate to neighborhood patterns. Excavation data was also examined as an alternate line of evidence for each case. The project contributes to the sparse literature on preindustrial urban neighborhoods. Research into social segregation or social clustering in modern cities is plentiful, but few studies examine the patterns of social clustering in the past. Most research in Mesoamerica focuses on the clustering of social class.

Environmental change has often been cited as affecting choices made whether to pursue cooperative or competitive strategies. The Flagstaff region provides a unique opportunity to address how environmental changes may affect choices made between competition and cooperation. Part of the region was a prehistoric frontier zone between three archaeological cultures and these groups had to contend with a marginal and highly variable climate for agriculture. These regional patterns of climatic variation are well documented and further the eruption of Sunset Crater Volcano in the midst of this frontier zone devastated local environments and reshaped the landscape. As groups re-colonized the frontier zone, they actively sought to negotiate new boundaries using both competitive and cooperative strategies that can be discerned archaeologically, including intergroup violence and the construction and use of communal ritual architecture. Dendroclimatological data is used to identify periods of environmental change and expectations for cooperative and competitive responses to these changes are developed based on anthropological theory and ethnographic case studies. These expectations are then tested against the archaeological record. Three lines of evidence are used to assess changes in levels of competition: (1) use of defensive sites, (2) presence of skeletal trauma, and (3) emergence of specialized social roles and weapons technologies. Two lines of evidence are used to assess changes in levels of cooperation (1) use of communal ritual architecture and (2) patterns of exchange. In some cases the expected relationships between favorable conditions and evidence of increased cooperation and between unfavorable conditions and evidence of increased competition are found. However, in other cases the expectations are not supported, with local historical and cultural contingencies appearing to override environmental influences. Contrasts between patterns of cooperation and competition found in the culturally diverse frontier zone versus the patterns found in the more culturally homogenous heartland are identified that suggest greater likelihood of the emergence of conflict in settings with pre-existing contexts of social differences.

Anthropological attention to landscapes has revealed them to be more than where people subsist: landscapes are inherently social entities. People create landscapes in their interactions with the environment and each other. People conceptualize, or imbue the landscape with meaning such that given places serve to impart cultural knowledge, identity, and social order. The link between people and their landscape thus underscores the importance of a landscape focus in the attempt to understand people. Furthermore, as a product of cultural behavior, the landscape constitutes a form of material culture that may be marked in ways that are consistent with how it is conceptualized. The material dimension of people's relationship with their landscape renders it a fruitful focus of archaeological inquiry. The main goal of this study is to identify how the Wixárika of Jalisco, Mexico, conceptualize the landscape, and to assess its relevance to understanding the ancient past. As adherents of a Mesoamerican tradition, the Wixárika offer a distinctive perspective on the landscape, and one with potential to elucidate the ancient past.

Given that a major share of a society's culturally significant cognitive features is expressed most productively by means of language, in this study I rely on aspects of language to ascertain Wixárika landscape conceptualization and materialization. Through the linguistic analysis of placenames and place-talk, I determine the meanings with which the Wixárika landscape is imbued. Through the analysis of the utterance of placenames, I provide examples of how the landscape is instilled with meaning. Utilizing native terminology, I characterize the content of the Wixárika landscape, and describe the process, in terms of movements, whereby the landscape is actualized.

Results indicate that the Wixárika conceptualize their landscape in diverse ways, including as a dwelling, a repository of memories, and a source of identity. The process and manifestation of Wixárika landscape conceptualization yield insights pertinent to understanding ancient landscapes, especially with regard to content and scope. This study is significant in that it represents the landscape from an indigenous perspective. It also sheds light on the construction of a living landscape, and thus is a useful framework for contemplating the past.
