Iron production was a particularly important precolonial African technology, with iron becoming a central component of socioeconomic life in many societies across the continent. Iron-bearing ores are much more abundant in the earth’s crust than those of copper, and in Africa, iron was recovered from these ores using the bloomery process, until the importation of European iron in the later second millennium eventually undermined local production. Although smelting was most intensively focused in regions where all the necessary components of a smelt were plentiful—iron ore, ceramic, fuel, and water—frequent occurrences of small-scale, local iron production mean that iron slag and associated remains are common finds on archaeological sites across Africa.
The archaeological remains found on iron production and iron-working sites can provide detailed information about the past processes that were undertaken at these sites, as well as the people involved with the technologies both as practitioners and consumers. A variety of analytical approaches are commonly used by archaeometallurgists to learn more about past iron technologies, particularly those methods that explore the chemistry and mineralogy of archaeological samples. By interpreting the results of these analyses in conjunction with ethnographic, historical, and experimental data, it is possible to reconstruct the techniques and ingredients that past smelters and smiths employed in their crafts, and address important questions concerning the organization of production, the acquisition of raw materials, innovations and changes in technological approach, and the environmental and social changes that accompanied these technologies.
Analysis of ceramics in archaeological contexts has provided a range of information regarding African history. Archaeologists have approached ceramics as a craft as well as an indicator of identity and status. The Africanist focus on the technological development of ceramic manufacture and production has taken several forms. The most notable are (1) the origins of ceramic production, (2) the spread and independent invention of this technology and regional styles through typological analysis, and (3) technological change related to the identity of the producers and consumers including changing dietary practices over time. The various arguments put forth for the first production and use of ceramics in different regions of the continent are connected to the exploitation of available resources such as fish as well as the rise of agricultural production. Following the appearance and technical history of ceramics in various regions of the continent, a focus on foodways and regional cuisine has placed ceramics at the forefront of interpretation.
Promoted by necessity, scarcity, and/or abundance, trade is one of the most essential cultural behaviors that promoted contact and exchange of ideas, commodities, and services between individuals and communities and variously transformed African societies of different regions and time periods. Anthropological, historical (including historical linguistics), and archaeological evidence points to the existence, on the one hand, of intra-African trade and, on the other, of external trade between Africa and those outside the continent. Traditionally, however, trade and exchange involving perishable and organic commodities such as grain and cattle have until now been very difficult to identify due to a lack of well-resolved documentation techniques. By comparison, that some objects such as metal artifacts, glass beads, ceramics, and porcelain are pyrotechnological products, with a high survival rate that makes their trade and exchange easily visible archaeologically. Given the well-known regional differences across the continent, it is essential to combine multiple sources and techniques, in a multipronged way, to provide a dynamic picture of the mechanics of precolonial African trade and exchange of various time periods and geographies.
The Maghrebi tradition of historical literary production extends back to the early centuries of Islamic expansion and conquest in North Africa and comprises a rich corpus including dynastic chronicles (tarikh), biographies (tarajim), and hagiographies (manaqib/rijjal), and, since the 20th century, positivist national histories as well. While this tradition had evolved since its inception, 19th- and 20th-century Maghrebi historical production both influenced and was influenced by the extension of European military, economic, and political power into the Maghreb. Grappling with the legacies of colonialism, nationalism, and pan-Arabism, among others, Maghrebi historians continue to sow the rich terrain of historical literary production in the postcolonial period by absorbing, reacting to, and building upon new trends in the historical profession.

Environmental constraints have large impacts on populations, especially in semi-arid regions such as Africa. Climate and weather have long affected African societies, but unfortunately the traditional climatic record for the continent is relatively short. For that reason, historical information has often been used to reconstruct climate of the past. Sources of historical information include reports and diaries of explorers, settlers, and missionaries; government records; reports of scientific expeditions; and historical geographical and meteorological journals. Local oral tradition is also useful. It is reported in the form of historical chronicles compiled centuries later. References to famine and drought, economic conditions, floods, agriculture, weather events, and the season cycle are examples of useful types of information. Some of the records also include meteorological measurements. More recently chemical and biological information, generally derived from lake cores, has been applied to historical climate reconstruction. Early works provided in most cases qualitative, discontinuous information, such as drought chronologies. However, a statistical method of climate reconstruction applied to a vast collection of historical information and meteorological data allowed for the creation of a two-century, semi-quantitative “precipitation” data set. It consists of annual indices related to rainfall since 1800 for ninety regions of the African continent. This data set has served to illustrate several 19th-century periods of anomalous rainfall conditions that affected nearly the entire continent. An example is widespread aridity during several decades early in that century.

Understanding paleoclimates has been an important component of archaeological research for over a century. Human settlement, mobility, and subsistence activities are predicated on interactions with the natural world, and by reconstructing the broader environmental context, archaeologists can recognize the primary external catalyst of cultural change. Modern paleoenvironmental reconstruction methods employ techniques developed over the last century as well as those that are at the frontiers of scientific inquiry. Archaeologists intent on providing basic environmental context must first describe the sedimentology of surficial deposits in order to understand landform evolution. Furthermore, descriptions of soils, which form in stable, weathered sedimentary deposits, are critical indicators of past climate. Soils are first described in excavation test units using macro-scale classification schemes, but increasingly microscopic techniques such as soil micromorphology in thin sections and DNA sequences of endemic microbiota are being used. Various types of plant and animal communities hosted in archaeological deposits also provide critical environmental details as they are often temperature and precipitation dependent. Generally speaking, the simpler and smaller the organism is, the more restricted its habitat tends to be. Therefore, microfauna and floral remains often provide the greatest level of precision in environmental reconstruction. Finally, light stable isotopes of carbon, oxygen, and nitrogen can be assayed from a wide variety of organic matter, and they provide specific information about biotic communities and precipitation that are useful to understand paleoenvironments. The simultaneous integration of multiple lines of evidence is being performed in archaeological research projects across the African continent and provides the best means to fully comprehend the framework in which human biological and cultural evolution occurred.
While there are a handful of defined methods for working with primary historical sources in archaeology, few archaeologists take these as their main points of departure or rely upon them too rigidly. This is to do both with the highly variable nature of the historical and archaeological material available for certain African contexts, and also with how archaeologists conceive of the relationship between these two bodies of evidence: as antagonistic, supplementary, entangled and subjective, mutually creative, and so on. Some methodologies focus on the potentials for consonance and dissonance between written and material sources. Others utilize oral traditions to provide insights into chronology, memory, historical and political dynamics, and the material aspects of these. Still other approaches focus on how historical and archaeological sources offer complementary perspectives on the local and the global, events and processes, and other shifts in scale. While these methods are diverse and contingent, they are united insofar as archaeologists take their cues from objects and from preoccupations with time and space. Archaeologists see their work concerning primary historical sources not as filling in gaps in written records but as addressing the partialities of the records themselves by engaging with an array of complex questions about meaning, authority, and materiality
Perspectives on southern Africa’s past in the eras before the establishment of European colonial rule have been heavily shaped by political conflicts rooted in South Africa’s history as a society of colonial settlement. The archive of available evidence—archaeological finds, recorded oral materials, and colonial documents—together with the concepts used to give them meaning are themselves products of heavily contested historical processes. Archaeological evidence indicates that Homo sapiens, descended from earlier forms of hominin, was present in southern Africa at least 200,000 years ago, but many members of the South African public reject evolutionary notions of the past. From about 200
