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.
From the period of the “Scramble for Africa” in the 1880s to the era of decolonization that began in the 1950s, culture and media played essential roles in constructing images of the colonized subject as well as governing newly conquered empires. In the struggle for political independence, Africans used film, music, literature, journals, and newspapers to counter European ideas about African society as well as to provide the foundations for postcolonial national identities. With sovereignty largely realized across Africa in the 1960s and 1970s, the roles of culture and media were critical in forging the bonds of nationhood and solidifying the legitimacy of the new states. However, those official efforts increasingly clashed with the aspirations of cultural activists, who desired a more thorough transformation of their societies in order to transcend the colonial legacy and construct progressive communities. Media and culture became a forum for political conflict whereby governments increasingly restricted creativity and subsequently sought complete control of the means of cultural creation and diffusion. Both the aspirations of public officials and opposition activists suffered during a period of prolonged economic crisis in Africa, which began in the 1970s and stretched into the 1990s. The sinews of governance as well as the radical pretensions of culture workers were torn asunder as many parts of Africa suffered state collapse, civil war, famine, and epidemic diseases (including the HIV/AIDS and Ebola crises). The dawn of the new millennium coincided with the age of neoliberal globalization that, for many African countries, was synonymous with structural adjustment programs and oversight from such international lending institutions as the International Monetary Fund (IMF) and the World Bank. This often required the privatization of media across Africa and included the greater prominence of non-African media sources on radio, television, and the cinema throughout the continent. It also was reflected in a shift among African culture workers, who frequently centered on the impact of globalization on African societies in their work. Filmmakers, musicians, and writers often use their platforms to speak to the wider world beyond Africa about the place of African societies in the globalized world.
