This article, largely on the basis of in-depth research in archives in Lisbon, provides an account of the trading systems linking Delagoa Bay to its southern hinterland. Within this framework we argue that the role of the slave trade has been previously underestimated. There is evidence that the booming demand for slaves in Brazil and on the Mascarene Islands hit this region with force. The scale of that trade is difficult to establish because it was, by and large, illicit and so not systematically recorded. There are indications of a significant trade prior to 1823 and a substantial one after that date. There is also evidence that northern Nguni groups, including the Zulu kingdom, were deeply involved in this trading system. The main sources of captives, however, were militarily weak societies, like the Tembe, which lived closer to the Bay.

This forum article explores the major intellectual trajectories in the historical archaeology of Eastern Africa over the last sixty years. Two primary perspectives are identified in historical archaeology: one that emphasizes precolonial history and oral traditions with associated archaeology, and another that focuses mostly on the era of European contact with Africa. The latter is followed by most North American practice, to the point of excluding approaches that privilege the internal dynamics of African societies. African practice today has many hybrids using both approaches. Increasingly, precolonial historical archaeology is waning in the face of a dominant focus on the modern era, much like the trend in African history. New approaches that incorporate community participation are gaining favor, with positive examples of collaboration between historical archaeologists and communities members desiring to preserve and revitalize local histories.

The development of small-scale kingdoms in the post-Roman world of northwestern Europe is a key stage in the subsequent emergence of medieval states. Recent excavations at Rhynie in north-eastern Scotland have thrown important light on the emergence of one such kingdom, that of the Picts. Enclosures, sculptured ‘symbol stones’ and long-distance luxury imports identify Rhynie as a place of growing importance during the fifth to sixth centuries AD. Parallels can be drawn with similar processes in southern Scandinavia, where leadership combined roles of ritual and political authority. The excavations at Rhynie and the synthesis of dated Pictish enclosures illustrate the contribution that archaeology can make to the understanding of state formation processes in early medieval Europe.

Cette contribution reconsidère le site de Garumele (Niger) à la lumière de récents travaux archéologiques. Garumele est dit dans les sources historiques avoir été la capitale de l'empire de Kanem-Borno peu avant la fondation de Birnin Gazargamo (deuxième moitié du quinzième siècle). Cet article reconcilie sources archéologiques et historiques pour évaluer la véracité de cette tradition – mais aussi pour considérer les facteurs méthodologiques et théoriques qui contribuent au mystère des origines du Kanem-Borno.

The Luzira head, a pottery figure discovered in a Ugandan prison compound in 1929, has remained curiously anonymous ever since. New archaeological work on the northern shores of (Lake) Victoria Nyanza has defined a formative period of political centralisation at the end of the first millennium AD. The authors show that this period of early to late Iron Age transition is where this remarkable object and related figurative material belongs. This has implications both for the formation of kingdoms in Uganda and for the story of African art more generally.

The monarchies and other polities of precolonial Madagascar exerted a strong influence on each other. For this reason, in recent years it has become more interesting to trace their inter-relationship than to emphasize their autonomy. The Betsimisaraka kingdom, which flourished on Madagascar's east coast in the early eighteenth century, has generally been regarded as a polity standing rather outside the mainstream of state formation in Madagascar, not least because of the identity of its founder, the son of an English pirate. Research in European and South African archives demonstrates the close connection between the Betsimisaraka kingdom and the Sakalava kingdom of Boina.
