This paper discusses the emergence of silver metallurgy some two millennia ago in the south central Andes. It is argued that the availability of multiple abundant resources and a high population density were instrumental in the development of this complex technology. The potential for such resource-rich environments to stimulate and sustain innovation is briefly discussed, particularly for prestige goods in societies engaged in socially competitive networks. The Puno Bay area of Lake Titicaca and its hinterland is shown to be one such resource-rich region, which may have contributed to its role in developing a complex and labour-intensive silver metallurgy as part of a larger mining-metallurgical landscape.

A community is an active assemblage of human and non-human elements bound together by interactions. Archaeologies of communities shed light on sets of overlapping and geographically emplaced assemblages of individuals, practices, spaces, buildings, objects, animals and landscapes. This article presents an archaeology of communities based a remarkably well preserved Late Formative (ad 1–500) patio group at Khonkho Wankane, Bolivia. Excavation data provide a high-resolution chronology and document two varieties of assemblages: (1) those that played a greater role in biologically and socially reproducing the community, such as daily food and tool production; and (2) those that played a greater role in its transformation, such as gatherings, work parties and construction projects. In the patio group, intimate meetings took place in small, private spaces where incense was burned. Larger gatherings took place in an outdoor space where painted Kalasasaya small jars and bowls were active elements in interactions between residents and visitors. These events most likely involved work parties that contributed to the physical and social construction of the community. Assemblages at multiple scales built a diverse Late Formative community, which played a principal role in regional interaction networks. Within a few generations of residents leaving their homes in Khonkho, local and regional interactions generated the emergence of a state at Tiwanaku.

The formation of a state on Crete at the beginning of the second millennium bc has usually been considered under the secondary state paradigm. Most explanations rely on the role of conspicuous consumption and emulation mechanisms at a time when Cretan elites were exposed to the developed stratified systems of the east Mediterranean. A careful review of the data, especially those derived from funerary contexts, struggles to identify such dynamics but reveals a varied range of identities being negotiated and redefined simultaneously at the local and regional level. Informed by ethnographic parallels, an alternative model for Crete is proposed in which change is understood as a social phenomenon that involved a wide proportion of the population and brought broad benefits that sustained the adoption and development of the transformed systems. Crete is presented as a rich archaeological example that may also help in rethinking similar processes in other parts of the Mediterranean and further afield.
