New Pathways of Sociopolitical Complexity in Southern Africa

Much is known about the economy and spatial organization of Zimbabwe culture entities of Mapungubwe, Great Zimbabwe and Khami but less in terms of their origins and relationship with each other. Based on little tangible evidence, it is believed and widely accepted that the societies based at Mapungubwe (ad 1220–1290), Great Zimbabwe (ad 1300–1450) and Khami (ad 1450–1820) rose, developed and eclipsed in tandem. A recent reexamination of the relationship between these settlements and related ones using local ceramics, imported artefacts, stone architecture and Bayesian modelling suggests this may not have been the case. The synthesis proffered revelations which temper the widely accepted assumption that sociopolitical complexity in southern Africa began in the Shashi-Limpopo Valley before anywhere else in the region. Firstly, there are numerous Zhizo and Leopard’s Kopje sites that predate Mapungubwe but contain prestige goods and stone structures dating from the late first millennium ad. Secondly, material culture studies and modelled radiocarbon dates indicate that Great Zimbabwe evolved out of Gumanye while Khami, like Mapungubwe, may have developed out of the Leopard’s Kopje. In fact, Great Zimbabwe was already a place of importance when Mapungubwe collapsed. Thirdly, Khami and Great Zimbabwe overlapped for over a century, before the latter buckled. Therefore, the evolution of sociopolitical complexity in southern Africa may have followed trajectories that are different from what the current understanding implies.     

The technology of tin smelting in the Rooiberg Valley,Limpopo Province,South Africa,ca. 1650–1850 CE

A substantial indigenous tin-smelting industry arose in the Rooiberg valley of northern South Africa in the second millennium CE. This study concentrates upon tin-smelting slags and refractory ceramics from two archaeological sites that date between ca. 1650 CE and ca. 1850 CE. These were studied by optical and electron microscopy, wavelength-dispersive x-ray fluorescence (WD-XRF), inductively-coupled plasma mass spectrometry (ICP-MS), and electron microprobe (EMPA). The slags are predominantly glassy; high SnO and relatively low SiO₂ contents indicate that tin is a major glass-forming element. Comparison of slag chemistries with the mineralogy of ore deposits and host rocks shows that alluvial cassiterite was used at one of the sites, while cassiterite from hard-rock mining was smelted at the other site. Since few preindustrial tin slags have been studied, we compare our findings to other published examples, mostly from southwest England.

Maritime Archaeology and Trans-Oceanic Trade: A Case Study of the Oranjemund Shipwreck Cargo, Namibia

Routine sand dredging for alluvial diamonds at Oranjemund on the southern coast of Namibia exposed remnants of a long forgotten Portuguese merchant ship believed to have wrecked in the 1530s. The rescue excavations yielded over 40 tons of cargo consisting of thousands of gold and silver coins, tons of copper and lead ingots, and large quantities of ivory together with food refuse, part of personal possessions and the superstructure of the ship. This paper discusses the cargo from the shipwreck. The varying provenances show that overland inter-and intra-regional networks fed into the maritime trade between Europe and the Indian sub-continent. As such, the wreck is a lens through which we can view what was happening on the seas as well as on land. Finally we consider wider issues raised by this discovery relating to the protection and management of such material wherever it may be found in future.     

Indigenous African Furnace Types and Slag Composition—Is there a Correlation?

Within variation, three major iron smelting furnaces were used in the Iron Age of sub‐Saharan Africa, ranging from the natural draught driven tall shaft to the forced draught powered low shaft and bowl furnaces. These furnace types are, however, mostly known from the ethnographic context. Often, archaeologists are confronted with remnants from the smelting process, forcing them to speculate on the anatomy of the extant furnaces. The presence of multiple fused tuyeres has been used to identify natural draught furnaces in the archaeological record. However, working back from smelting remains such as slag to the furnace type using physical and chemical evidence has generally proved to be ‘undoable’. Thus, when randomly selected, the chances are high that one cannot separate bowl furnace slags from those that formed in their tall or low shaft counterparts. This observation is hardly unexpected; analogous thermodynamics and thermo‐chemical reactions governed bloomery smelting irrespective of furnace type. Rehren et al. (2007) have labelled this phenomenon the ‘tyranny of system driven constraints’. In this study, we argue that the hierarchical use of statistical methods may add another layer of evidence which, when coupled to archaeological indicators, may be useful in correlating slag chemistry to furnace types used in antiquity.     

Seen but Not Told: Re-mapping Great Zimbabwe Using Archival Data,Satellite Imagery and Geographical Information Systems

The world renowned site of Great Zimbabwe is one of the most globally significant archaeological sites in Africa. Ironically, this importance is not matched by the little amount of information that is known about such an iconic site. The heritage of this regrettable situation was birthed by the destructive activities of late nineteenth and early twentieth century antiquarians who vandalised tons of evidence without record. Throughout the twentieth century, however, professional archaeologists made interventions that rescued information from various parts of the site but most of which was never published. A moratorium imposed on archaeological excavations at the site in the early 1990s failed to stimulate an active engagement with material that was archived since the first professional excavations began. Motivated by the need to understand the site in new ways, research was initiated to revisit the site’s patchy and scattered archives and to supplement them with field surveys. This paper discusses the re-mapping of the site which, for the first time, comprehensively produced themed layers of spatial, chronological and material culture distribution. The main outcome is that most existing maps ignored a large number of terraces on the hill and omitted evidence of occupation in key areas. When combined with excavation profiles that expose the massive rebuilding of the site by original residents, it becomes clear that settlement ebbed and flowed during the more than six centuries of occupation at the site.     

Ores, Furnaces, Slags, and Prehistoric Societies: Aspects of Iron Working in the Nyanga Agricultural Complex, AD 1300–1900

The Nyanga agricultural complex through its cultivation terraces and ridges represents one of the most intensified agricultural systems in southern African prehistory. In such a well developed system of land management and use, iron tools played a crucial role in clearing the land for cultivation as well as for domestic building purposes. Important to this dimension is the need to understand iron production and use in prehistoric societies. This paper aims for the first time to look at iron technology in the Nyanga agricultural complex through an initial analysis of iron extraction remains such as ore, slag, and furnace fragments. As a result, the technical data obtained will be used to develop hypotheses which future research can engage. This paper is a preliminary statement toward developing an understanding of iron production to meet various purposes from the deeper past to the historical period.Le complexe agricole Nyanga avec ses terrasses et collines cultivées représente un des systèmes agricoles les plus intensifs de la préhistoire de l'Afrique du sud. Dans ce système d'organisation et d'exploitation bien développé les outils en fer jouent un rôle important dans la cultivation du sol et la construction des bâtiments. Il est nécessaire de bien connaître les méthodes de production et d'utilisation du fer dans les sociétés préhistoriques. Cet article traite pour la première fois de la technologie du fer dans le complexe agricole Nyanga en présentant des analyses préliminaires des restes de l'exploitation du fer tels les minerais, les scories et les fragments de fourneaux. Les résultats de l'étude de ces techniques vont servir à développer des hypothèses qui aideront à faire avancer les recherches futures. Cet article représente un essai préliminaire pour développer nos connaisaences sur la production du fer destiné à de multiples usages depuis les temps les plus reculés jusqu à la période préhistorique.     

Decisive Evidence for Multidirectional Evolution of Sociopolitical Complexity in Southern Africa

While pioneers of archaeology in any given region have established the foundations of the discipline, their views have not remained unchanged in places such as Europe, North America and Australasia. In these regions, successive generations of researchers changed the direction of their work based not just on new observations but also in light of new methods and theories. For example, the idea of a Bronze Age revolution popularised by V. G. Childe in Europe was superseded by multiple alternatives over the years. In southern African Iron Age studies, John Schofield, Gertrude Caton-Thompson, Roger Summers, Keith Robinson and Peter Garlake created an impressive platform upon which successors could build. Confronting firm disapproval from more experienced researchers in the early 1980s, Huffman speculated that the evolution of sociopolitical complexity in our region was a linear relay from Mapungubwe to Khami via Great Zimbabwe. This position was sustained as the conventional wisdom largely, we argue, because no new research was being carried out in key areas of the region, and too few students, in particular African ones, were being trained to expand the focus of investigation. Here, we present new data to support our argument, that the pathway to sociopolitical complexity in southern Africa was multilinear. We propose looking forward rather than back, and to continue to seek the exposure of scales of interaction between multiple but chronologically overlapping entities associated with the rise of sociopolitical complexity in southern Africa.     

Exotica in Context: Reconfiguring Prestige,Power and Wealth in the Southern African Iron Age

Prestige goods, in various combinations and permutations, feature prominently in anthropological and archaeological templates of the emergence of social inequality and early state formation in premodern societies. In Africa, discussion of the contribution of prestige goods to the evolution of cultural behaviours such as class distinction and statehood has been conducted primarily through theoretical lenses that allocate significant weight to the proceeds of external long distance trade. The major outcome is that archaeologists have rarely paused to evaluate not just the definition of prestige goods but also the congruity between global ‘universals’ and African ‘particularities’. Using empirical evidence from the southern African historical and archaeological records, this paper seeks to evaluate the concept of prestige goods and to assess their contribution to the evolution of Iron Age (AD 200–1900) communities of different time periods, from locally centred positions. It reveals that the distribution, use and deposition of exotic imports in southern Africa is not compatible with the pattern suggested by the prestige goods model, and points towards their valuation as embedded within situational contexts of meaning. In fact, hinterland elites controlled neither the source nor the distribution of exotic goods from producer regions, making them a volatile source of power and prestige. While local elites used exotic imports when available, and imposed taxes on their citizens—payable in both local and external goods—land, cattle, religion and individual entrepreneurship were far more predictable and stable sources of prestige, wealth and power. This provides the basis for reassessing the development of complexity in the region and potentially contributes towards global debates on the impact of long-distance trade in the development of complex states.     

Post-colonial heritage conservation in Africa: perspectives from drystone wall restorations at Khami World Heritage site,Zimbabwe

Abstract

Before colonialism, heritage sites such as Khami were considered resting places for ancestors, valued more for the spirit of place than their monumentality. In this context, local custodians hardly intervened with the fabric of the site. With the introduction of modern conservation principles, which persist to this day, vegetation control and wall restorations became part of routine conservation measures. This paper discusses drystone wall restorations carried out at Khami between 2000 and 2015 focusing on the disjuncture between indigenous and local concepts of heritage, concerned with access and preserving the spirit of ancestors, and ‘western’ principles of restoration. It argues that while ignoring the structural disintegration of Khami would have resulted in possible delisting from the World Heritage List, the ‘neglect’ which Khami experienced was in tandem with its local social context; being a resting place for ancestors. While the reconstructions interfered with an acceptable physical context of local beliefs, restorations maintained the integrity of the site as a tourist destination with positive local economic benefits. Although compromises are by their nature unsatisfactory, modern heritage conservation in Africa must adapt and improvise to achieve a mix of local and international practices to reflect changed and changing realities.
