Origin and Collapse of Complex Societies in Oaxaca (Mexico): Evaluating the Era from 1965 to the Present

I summarize recent archaeological work in Oaxaca, Mexico, with a focus on questions central to world prehistory: the origin and collapse of complex societies. Monte Albán was the capital of an emerging civilization in the southern highlands of Mexico during the second half of the first millennium B.C. Soon after the foundation of the ancient city, there is evidence for state formation and a political expansion into regions outside the Valley of Oaxaca. Centuries later, Monte Albán went into decline, giving way to the competing small polities found throughout Oaxaca at the time of the Spanish conquest. Since the late 1960s, our knowledge of these changes has been transformed by study of Oaxaca's pre–Monte Albán past, regional settlement surveys, and processual model building. Evolutionary and historical perspectives allow for significant refinement of current debates surrounding the rise and fall of complex societies in Oaxaca.     

Crema Ware and Elite Power at Monte Albán: Ceramic Production and Iconography in the Oaxaca Valley,Mexico

Abstract

During the Terminal Formative, or Monte Albán II period (ca. 100 B.C.-A.D. 200), the Zapotec state was centered in the Oaxaca Valley, Mexico. Reassessment of ceramic data from excavations at the Zapotec capital of Monte Albán, in conjunction with data acquired from recent investigations at a secondary center (Cerro Tilcajete) and a tertiary center (Yaasuchi) in the Oaxaca Valley, sheds light on the production and distribution of elaborately decorated crema- (cream-) paste ceramics. This analysis suggests that such ceramics were produced at Monte Albán as prestige goods and distributed to local elites residing at administrative sites throughout the valley. The distribution of decorated crema vessels—and in particular, bowls bearing incised lightning motifs associated with the preeminent Zapotec deity, Cociyo—via gift-giving networks represented an attempt by elites at the capital to control local elites and integrate them into the regional sociopolitical hierarchy. Data from Cerro Tilcajete and Yaasuchi indicate that local elites at these centers acquired and used some crema vessels. These vessels were fewer in number and less varied than the cremas enjoyed by elites at the capital. Elites at Cerro Tilcajete and Yaasuchi apparently sponsored the local production of ceramics intended to imitate crema vessels. By supplementing the flow of true crema ceramics from Monte Albán, the production of local imitations would have subverted attempts by elites at the capital to control both the distribution of prestigious ceramics and the subordinate elites who desired them. This regional study of ceramics in the Oaxaca Valley illustrates the intersection of economy and ideology in state society, as well as the role that prestige goods can play in the creation and legitimization of—as well as resistance to—institutionalized sociopolitical difftrences.     

‘M GLOW BLUE’: ARCHAEOMETRIC RESEARCH AT MICHIGAN'S FORD NUCLEAR REACTOR

The Ford Nuclear Reactor operated from 1957 to 2003 on the University of Michigan's North Campus in Ann Arbor, Michigan. Over its 45‐year lifespan, the facility played a key role in archaeometric research, fostering early methodological studies using INAA and supporting archaeological materials science investigations of lithics, ceramics, metals and bone. One small part of the FNR's abundant legacy was the initiation of trace‐element studies of Oaxacan ceramics, which are now beginning to shed light on early exchange interactions and the origin of the Monte Albán state in the Valley of Oaxaca, Mexico, between 500 bce and 200 ce .     

Ceramic Microtypology and the Territorial Expansion of the Early Monte Albán State in Oaxaca,Mexico

Abstract

The Late and Terminal Formative (ca. 300 B.C. to A.D. 200) was the crucial period during which the early Monte Albán state came into being and began to extend its political influence over a wide area in what is now the Mexican state of Oaxaca. One of the most distinctive and frequent ceramic types of this period is the G.12, which is a grayware (gris) bowl with characteristic incising on the interior rim and base. Originally defined by Alfonso Caso, Ignacio Bernal, and Jorge Acosta based on their excavations at Monte Albán, the G.12 bowl has also been found at many other Oaxacan sites. The incised motifs on the interior bases of G.12 bowls show substantial variability, but researchers have been uncertain whether any portion of this variability shows chronological patterning. We present a new microtypology of G.12 bowls based on our recent excavations at three sites near SanMartín Tilcajete, some 27 km south of Monte Albán. Our analysis yields a finer-grained chronology that helps elucidate the step-by-step territorial expansion of the emergent Monte Albán state.     

Domestic Faunal Assemblages from the Classic Period Valley of Oaxaca,Mexico: A Perspective on the Subsistence and Craft Economies

During the Classic period (ad 200–800), urban Monte Albán in the Valley of Oaxaca was one of the most monumental cities in Mesoamerica. Yet relatively little is known about the Classic-period economy that sustained this prehispanic centre. In this paper, we compare the faunal assemblages at two outlying Classic-period sites located in the central valleys of Oaxaca—Ejutla and El Palmillo. This analytical comparison provides a new empirical perspective on two important aspects of the ancient Oaxacan economy, subsistence strategies and household craft manufacture. Although Ejutla and El Palmillo have rather distinct environmental settings, the faunal component of the diet at the sites is found to be similar with some subtle differences. More marked distinctions between the sites are noted in the use of bone as a raw material for tools and ornaments. When the findings from the faunal comparison are situated within the context of other domestic remains from Classic-period Ejutla and El Palmillo, intraregional variation in household strategies of production and exchange is evidenced, providing a preliminary vantage on the complex economy that underlay this prehispanic polity.     

A processual study of Inka state formation

Traditional interpretations of how the Inka empire developed emphasize the disjunctive transformation of a village-level society through the agency of a single charismatic ruler. New evidence from the Inka heartland indicates that it was in fact the formation of a centralized state in the Cusco Valley of highland Peru that enabled the rapid campaigns of Inka territorial expansion during the 15th and 16th centuries. By using archaeological data and ethnohistoric documents to develop independent lines of evidence, it is possible to describe Inka state formation processes anthropologically. Settlement and excavation data from the Vilcanota Valley provide several indicators of the development of a centralized Inka state during the Killke Period (c. A.D. 1000–1400), while multiple accounts of the Inka past describe the transformation of Inka society over a period of several generations leading up to the first campaigns of imperial conquest. Both lines of evidence are consistent with the kinds of changes described for other known cases of state formation. The formation of the Inka state and its expansion in the Cusco region created conditions in which the agency of Inka rulers could direct the expansion of a mighty empire in only a few generations of conquest.     

ASSESSING NATURAL CLAY COMPOSITION IN THE VALLEY OF OAXACA AS A BASIS FOR CERAMIC PROVENANCE STUDIES

The Oaxaca Clay Survey was initiated to provide baseline data on clay composition within the Valley of Oaxaca, Mexico, to assist in provenance determination of prehistoric ceramics. Natural clays were sampled from 135 locations throughout the valley, and analysed using INAA in combination with ceramic petrography. Observed geographical trends in trace‐element and mineralogical composition confirm that while parent material (surficial geology) strongly affects clay composition, a continuum of variation exists within the valley. The study develops and tests a continuous spatial model of clay composition that provides greater resolution in ceramic sourcing than bedrock alone. By establishing a regional framework for Oaxaca Valley clays, the survey will support significant advances in our understanding of pottery production and exchange within the valley, and provide a more robust means for monitoring exchange between the valley and neighbouring regions.     

Some Political Processes of Ranked Societies

This article explores the emergence of inequality in two regions of Mesoamerica: the Soconusco and Valley of Oaxaca. Dichotomous models that propose a continuum of political strategy (i.e., Leach 1954; Renfrew 1974; Spencer 1993; Blanton et al. 1996) are used to examine the different processes evident in the comparison of settlement, mortuary, and architectural data between these two regions. The elite in Early and Middle Formative Soconusco appear to integrate society with a comparatively external oriented and exclusionary strategy whereas in the Valley of Oaxaca Early and Middle Formative elites employed a more group-oriented, internally focused, and corporate strategy. Environment richness and proximity of competing communities may account for the primary, and perhaps unintentional, emergence of inequality in the Soconusco around 1400 B.C.E. In the Valley of Oaxaca inequality emerged as many as 250 years later in a less circumscribed area. Such environmental, political, and chronological factors may be responsible for some of the differences in integrative strategies evident in the two regions.     

Managing the risk of climatic variability in late prehistoric northern Chile

The concept of risk management encompasses the diverse strategies employed in preventing and mitigating losses associated with social and environmental calamities. Building on the growing literature on risk, we use archaeological data from the Tarapacá Valley, located in northern Chile, to document the risk-reduction tactics mobilized by the valley’s inhabitants to navigate the increasingly volatile environmental and social conditions of the Late Intermediate Period (AD 1000–1450). With the onset of exceptionally unpredictable environmental conditions after AD 1100, residents of the Tarapacá Valley chose strategies such as increased trade and agricultural diversification and extensification to minimize shortages in staple resources. Threats of raiding and intra-community strife exacerbated the risks associated with subsistence shortfalls. Valley communities elected a number of strategies to curtail conflict-induced risk, including movement of settlements and field systems to defensible locations, construction of walls and other defensive features, and the introduction of plazas. Rock art data suggest that trade was increasingly embedded in ritually sanctioned events involving groups from different ecological zones. While studies of risk have focused disproportionately on environmental hazards, subsistence-related crises are often compounded by social hazards that require their own risk-mitigating strategies, further constraining options for coping with subsistence stress.     

Boundaries,scale, and internal organization

The abstract systems properties of size, centralization, and boundary permeability are related in a theoretical model, wherein size and permeability are positively associated and these two properties are in turn negatively associated with centralization. The model is tested with regional archaeological survey data for 1500 B.C.–A.D. 1520 from the Valley of Oaxaca, Mexico. The results point out the conditions under which the model does and does not hold in the cultural evolution of this complex society.     

Chiefdoms at the threshold: The competitive origins of the primary state

The origins of the primary state are examined, paying particular attention to the interacting complex chiefdoms that precede state formation. A comparative analysis is undertaken of the evolutionary trajectories of two well-documented cases of prehistoric complex chiefdoms in North America and Mesoamerica: Cahokia and Monte Albán. Of special concern are the strategies that the rulers of these powerful, expansionist chiefdoms pursued in response to varying conditions of local competition or resistance. The crucial difference between the two developmental outcomes, the analysis concludes, derived from the varying degrees of inter-polity competition confronted by Cahokia and Monte Albán. The higher level of inter-polity competition in Monte Albán’s case required a complete administrative transformation in order for the leadership’s goal-oriented, expansionist strategies to succeed, resulting in the successful formation of a primary state.     

Unintended effects of technology on climate change adaptation: an historical analysis of water conflicts below Andean Glaciers

Climate change adaptation measures can generate long-term unintended consequences, as this paper demonstrates through an empirical case study of water conflicts at Lake Parón in Peru’s Cordillera Blanca mountain range. This decade-long struggle culminated in 2008 when a coalition of local groups (stakeholders) from the Cruz de Mayo and Caraz communities in the Callejón de Huaylas seized control of the Lake Parón reservoir from a private multinational corporation, Duke Energy. This clash over Parón’s water in the Llullán and Santa River watersheds emerged much earlier than climatic-hydrologic models had predicted, and it occurred, this paper argues, largely because of previously successful climate adaptation measures. The drainage tunnel and floodgates originally installed at Parón in the 1980s to prevent a climate-related outburst flood led to unintended or perverse outcomes because these technological artifacts subsequently allowed a diversity of stakeholders—including rural subsistence farmers, urban residents, national park officials, tourism promoters, the state energy company Electroperú, and Duke Energy—to manage water differently depending on their priorities and the existing governance structures. Neoliberal reforms that altered state-society-environment relations in Peru played a key role in these changing stakeholder power dynamics that were reflected in the management of water infrastructure at Parón. Examining this water conflict that emerged from the unintended effects of climate adaptation demonstrates not only how technology and society are mutually constitutive, but also why the politics of technologies must be considered more carefully in the analysis of social-ecological systems, hydro-social cycles, and climate change adaptation.     

Commoner Power: A Case Study from the Classic Period Collapse on the Oaxaca Coast

This article argues that the agency of commoners has not been adequately theorized in archaeological studies of the political dynamics of complex societies. Recent developments in social theory emphasize that political relations are produced through social negotiations involving commoners as well as elites. This paper considers the role of commoners in the Classic period collapse in the lower Río Verde Valley, Oaxaca, Mexico. Regional survey and excavation data demonstrate that the Classic-to-Postclassic transition was marked by dramatic changes in settlement patterns and sociopolitical organization, including the decline of the Late Classic regional center of Río Viejo. The research indicates that rather than passively reacting to the sociopolitical developments of the Classic-to-Postclassic transition, commoners actively rejected many of the ruling institutions and symbols that were central to the dominant ideology of the Late Classic state. Early Postclassic people reused and reinterpreted the sacred spaces and objects of the Río Viejo state such as carved stone monuments and public buildings. The evidence from the lower Verde is examined in the context of an emerging theoretical perspective in archaeology that considers commoner power. We argue that commoners contribute to the social negotiation of dominant discourses through three overlapping forms of social interaction: engagement, avoidance, and resistance.     

The origins and development of complex prehispanic society in the Lower Santa Valley,Peru: Implications for theories of state origins

A major issue in attempts to construct cross-culturally valid theories of state origins is the relative roles of irrigation agriculture, population growth, and warfare in the rise of complex society. Recently, data from the coast of Peru has provided the stimulus for the formulation of the “coercive theory” of state origins. This theory proposes that state formation in circumscribed environments was the result of population pressure, internecine (local level) warfare, and the incorporation of defeated groups into ever larger, victorious polities. Yet, although the pioneering study of settlement patterns was carried out in Virú Valley, the lack of a comprehensive regional study of the development of prehispanic subsistence-settlement systems in any Peruvian coastal valley meant that the “coercive theory” rested on a precarious data base. Selected results of an extensive and systematic survey carried out in 1979–1980 in the Lower Santa Valley, an area only partly studied prior to our research but long famous for its large number of major prehispanic walls and fortresses, are discussed. Following a discussion of the problem, research methods and data for the early periods leading to state formation are outlined. Analysis of settlement patterns, maize-based carrying capacity, and settlement-cluster ceramic assemblages is then carried out to suggest refutation of the “coercive” model and acceptance of an alternative model of multivariate causality. External, or intervalley, warfare is shown to have been an important socioenvironmental stress leading to sociocultural complexity not only in Santa, but probably in adjacent valleys as well.     

‘Es honor de su nación’: Legal Rhetoric,Ethnic Alliances and the Opening of an Indigenous Convent in Colonial Oaxaca

This article examines the manner in which the caciques (noble Indians) and principales (Indian notables) from the Oaxaca region in New Spain adopted a ‘legal rhetoric’ in their quest to open a convent for noble Indian women during the eighteenth century. Through a close reading of the legal documentation produced in the petition for the convent for indigenous women in Antequera, I find that the caciques strategically used the same laws that had placed them in a subordinated place in the social hierarchy of the colony in order to negotiate certain rights and privileges. Aware of their belonging to the legally determined category of ‘Indians,’ indigenous peoples from the Valley of Oaxaca appealed specifically to the laws that had granted them a special judicial place in the colonial scheme. By referencing the Recopilación de las leyes de las Indias and several royal decrees (cédulas), the caciques appealed to colonial officials at a key historical moment, when Bourbon reforms sought to modernize all institutions, including the Catholic Church.     

瓦哈卡:多元文明的民间传承

瓦哈卡城是墨西哥瓦哈卡州的首府,不同时期的历史遗存在这里交相辉映、相得益彰,1987年,联合国教科文组织将瓦哈卡历史中心和阿尔班山考古遗址列入《世界遗产名录》,在此后不到三十年的时间里,瓦哈卡市建立起了完善的遗产管理体系,大量的博物馆和历史遗迹,由政府和民众共同保护着,在保留了殖民时期文化要素的基础上,通过博物馆和学校的传播,增强了当地土著族群对自身文化的自信心和认同感,     

Culturally modified skeletal remains from the site of Huamelulpan,Oaxaca, Mexico

A series of crania from the site of Huamelulpan, Oaxaca, Mexico (400 BC to AD 800), were examined. Four showed notable cultural modifications. One exhibited a healed trephination, while the other three were perforated through the frontal. The cultural context and significance of these modifications is discussed, especially in relationship to the site of Monte Albán, where trephination was more common than anywhere else in Mesoamerica. The post-mortem cranial perforations appear to be connected with the practice of ancestor veneration. © 1997 John Wiley & Sons, Ltd.     

New radiometric dating of water management features at the prehistoric Purrón Dam Complex,Tehuacán Valley,Puebla, México

Recent investigations at the prehistoric Purrón Dam Complex in the Tehuacán Valley of southern Puebla, México applied radiometric dating to more securely date the complex. Ceramic-based dating in the 1960′s placed the Dam's origin to the Formative Period. While Formative Period origins are widely accepted, the chronology lacks resolution and direct dates. Samples from impounded sediments behind the dam and from prehistoric canal fill were dated through Optically Stimulated Luminescence (OSL) as well as both standard ¹⁴C and accelerated mass spectrometry (AMS) assays. These samples directly date the functioning of the water management features within the complex. The results confirm the Formative Period origins of the Purrón Dam, and offer new insights into the construction and functioning of the dam and irrigation system.     

Feminicide as ‘act’ and ‘process’: a geography of gendered violence in Oaxaca

Feminicide in Mexico is most notoriously associated with the serial deaths of women in and around Ciudad Juárez. A 2005 congressional investigation expanded, nonetheless, the geographical scope of feminicide, arguing that the phenomenon was present throughout the country. One location that was identified early on as also experiencing a high rate of feminicide was the state of Oaxaca, in the southern part of Mexico. Inscribed within this shifting geopolitical terrain, this article draws on an understanding of feminicide as both act and process in order to offer a critical portrayal of feminicide in Oaxaca. Beginning with a discussion of the profiles of feminicide in Oaxaca, the analysis moves out to explore the multifaceted processes that enable feminicide to occur. In so doing, we also explore how feminicide intertwines with other forms of social and political violence in Oaxaca. From an ethical-moral terrain, this article joins a broader movement in certain corners of feminist geography that is concerned with ‘making bodies count’ and the politics of witnessing acts of violence.     

A spatial method for integrating data of different types

Systematically recording archaeological, historical, ethnographic, and other information in a geographical-temporal frame has great advantages. The method allows the logical ordering of disparate facts, error checking, making connections that might otherwise go undetected, better comparison, manipulating temporal and spatial scales, and specifying the fields within which causal processes do and do not operate. The application of this spatial method in the Valley of Oaxaca, Mexico, generated new hypotheses about the late prehispanic-earlies colonial transition; it brings us closer to a single history, as opposed to segregated prehistory and history.
