The study of West Africa has contributed to the expansion of comparative arid-lands floodplain prehistory, from both the data collection (cultural and historical) and the theoretical aspects. The neoevolutionary approach that often pictures Africa as a backward continent has been successfully challenged. In the Middle Senegal Valley and in the Inland Niger Delta, research on their societies’ complexity done along these two subcontinent’s floodplains has described new processes (including urbanization) that were not previously featured in the archaeological literature. The two floodplains, because of their ecological diversity, with the richness of their ecological diversity, attracted Saharan populations affected by drought at the end of the second millennium and the first millennium BC. However, after their initiation occupation the two areas took different trajectories in complexity and settlement organization. Large complex settlements have been found at Jenne-jeno and in the Ile a Morphil that illustrate whole new trajectories of civilization. These forms of complexity, found in areas with historically known polities, were not included in the range of possibilities predicted by standard complexity theories regarding civilizational development. Ethnographic and historical data, reveal the existence of societies with a central authority embedded within and balanced by a diffuse, segmented and heterarchical power structure; often as a strategy to resist the individual consolidation of power. These societies exhibit evidence of horizontal differentiation and consensus-based decision making. All these types of organization are characterized by the presence of several sources of power vested in corporate entities, such as lineages, age groups, cults and secret societies.

Southern Nigeria is rich in copper alloy cast works, such as those of the 9th-century burial goods of Igbo-Ukwu, the busts from 13th-century Ife, and the heads and plaques from the early 16th century from Benin City. Much scholarship has been devoted to these centers and yet there are other, perhaps even more historically important, works which have barely been acknowledged. The label “Lower Niger Bronzes” was proposed in the 1960s by William Fagg to account for those few pieces which did not fit with the three well-known centers’ works.
On closer examination, these bronzes are far more numerous and of greater antiquity than previously realized. The quality and composition of these works indicate that most were likely cast prior to the European coastal trade in Nigeria which dates from the late 15th century. Leopard skull replicas, humanoid bell heads, small hippos, scepter heads, and masks make up only a portion of the works now under study. Without their original cultural contexts, these artifacts are somewhat mysterious, yet with careful study of their compositions and forms, much is revealed of a period of southern Nigerian history which predates the current arrangement of ethnic groups.
The West African savannas are a major area of independent plant domestication, with pearl millet, African rice, fonio, several legumes, and vegetable crops originating there. For understanding the origins of West African plant-food-producing traditions, it is useful to have a look at their precursors in the Sahara during the “African humid period” between 10,500 and 4,500 years ago. The Early and Middle Holocene Saharan foragers and pastoralists intensively used wild grasses for food but did not intentionally cultivate. Due to increasing aridity in the late 3rd millennium
The Mali Empire is one of the largest and most widely known precolonial African states. It has featured in films, video games, works of fiction, and its memory is still a profound force in the articulation of social and political identities across Mande West Africa. Founded in the 13th century in the south of modern Mali, it quickly grew from a small kingdom to a vast empire stretching from the Senegambia in the west to Ivory Coast in the south. Before its disintegration in the late 16th century, its connections to distant trade networks stretched from Europe to China and its rulers became famous across the Old World for their wealth. In the absence of indigenous written histories, knowledge of the Mali Empire has been based on a complex combination of oral traditions, medieval Arabic chronicles, European accounts, oral histories, and archaeology. Through a critical analysis of these sources, it has been possible to learn much about Mali’s history, including aspects its social organization, political structure, belief systems, and historical evolution. However, there is much we still do not know, including the location and nature of its capital(s).

Recent narratives on the origin of food production in the West African forest zone have replaced earlier diffusion-based models with viewpoints that emphasize the diversity of sources for plants and animals exploited and domesticated in the region. Management of indigenous tree species, including oil palm and incense tree, managed first by indigenous foragers, have the longest history in the area, dating back to over 8,400 before present (
In the early 21st century, understanding West Africa’s Stone Age past has increasingly transcended its colonial legacy to become central to research on human origins. Part of this process has included shedding the methodologies and nomenclatures of narrative approaches to focus on more quantified, scientific descriptions of artifact variability and context. Together with a growing number of chronometric age estimates and environmental information, understanding the West African Stone Age is contributing evolutionary and demographic insights relevant to the entire continent.
Undated Acheulean artifacts are abundant across the region, attesting to the presence of archaic Homo. The emerging chronometric record of the Middle Stone Age (MSA) indicates that core and flake technologies have been present in West Africa since at least the Middle Pleistocene (~780–126 thousand years ago or ka) and that they persisted until the Terminal Pleistocene/Holocene boundary (~12ka)—the youngest examples of such technology anywhere in Africa. Although the presence of MSA populations in forests remains an open question, technological differences may correlate with various ecological zones. Later Stone Age (LSA) populations evidence significant technological diversification, including both microlithic and macrolithic traditions. The limited biological evidence also demonstrates that at least some of these populations manifested a unique mixture of modern and archaic morphological features, drawing West Africa into debates about possible admixture events between late-surviving archaic populations and Homo sapiens. As in other regions of Africa, it is possible that population movements throughout the Stone Age were influenced by ecological bridges and barriers. West Africa evidences a number of refugia and ecological bottlenecks that may have played such a role in human prehistory in the region. By the end of the Stone Age, West African groups became increasingly sedentary, engaging in the construction of durable monuments and intensifying wild food exploitation.
From at least 3.4 million years ago to historic periods, humans and their ancestors used stone as the raw material for tool production. Archeologists find stone tools on all the planet’s habitable landmasses, even in its cold and ecologically sparse Arctic regions. Their ubiquity and durability inform archeologists about important dimensions of human behavioral variability. Stone tools’ durability also gives them the ability to contribute to the study of long-term historical processes and the deeper regularities and continuities underlying processes of change. Over the last two millennia as ceramics, livestock, European goods, and eventually Europeans themselves arrived in southern Africa, stone tools remained. As social, environmental, economic, and organizational upheavals buffeted African hunter-gatherers, they used stone tools to persist in often marginal landscapes. Indigenous Africans’ persistence in the environment of their evolutionary origins is due in large part to these “small things forgotten.” Stone tools and their broader contexts of use provide one important piece of information to address some of archaeology and history’s “big issues,” such as resilience in small-scale societies, questions of human mobility and migrations, and the interactions of humans with their environments. Yet, stone tools differ in important ways from the technologies historians are likely to be familiar with, such as ceramics and metallurgy, in being reductive. While ceramics are made by adding and manipulating clay-like substances, stone tools are made by removing material through the actions of grinding, pecking, or fracture. Metals sit somewhere in between ceramics and stone: they can be made through the reduction of ores, but they can also be made through additive processes when one includes recycling of old metals. Stone-tool technologies can also be more easily and independently reinvented than these other technologies. These distinctions, along with the details of stone tool production and use, hold significance for historians wishing to investigate the role of technology in social organization, economy, consumption, contact, and cultural change.
Political complexity in archaeological research has traditionally been defined as socio-political differentiation (roles, statuses, offices) integrated through centralized systems of power and authority. In recent decades the assumption that complex organizational forms tend to be hierarchical in structure has been called into question, based upon both archaeological research and ethnological observations worldwide, including in classic archaeological case studies of centralization. Moreover, there has been an increasing interest in exploring variability in political legitimizations and articulations of power and authority globally. Until these theoretical shifts, West African complex societies, both archaeological and from ethnographic analyses, were largely ignored in discussions of political complexity since many (but not all) conformed poorly to the expectations of highly centralized power and administration. West African ethnohistoric and archaeological examples are now playing important roles in current discussions of heterarchical organizational structures, checks on exclusionary power, cooperation, urbanism, ethnicity, and the nature of administration in states.
