Summary and Keywords
The urban history of Africa is as ancient, varied, and complex as that of other continents, and the study of this history shares many of the theoretical, conceptual, and methodological challenges of urban history generally. Knowledge of Africa’s historic cities is based on archaeological investigation, analysis of historic documents, linguistics, and ethnographic field methods. The historiography of cities in Africa has debated what constitutes a city, how urbanization can be apprehended in the archaeological record and in documentary sources, why cities emerged, and how historic cities have related to states. The great impact colonization had on African urbanization is a major topic of research, including in the study of postcolonial cities. The “informality” of much contemporary urbanization, both in terms of economic activities and architecture, has been a major topic of research since the 1970s.
With few exceptions, prior to the 20th century cities were relatively small, with no more than 20,000–30,000 inhabitants. Religion, trade, and the concentration of power were major factors in the rise of cities across the continent. The largest and most well-studied cities were often the capitals of important states. At times networks of city-states flourished, as in Hausaland, Yorubaland, and along the Swahili coast. The cities of northern Africa shared many morphological characteristics with other cities of the Mediterranean Basin and the Middle East, being characterized by a high density of population, masonry architecture, and encircling city walls. South of the Sahara, cities tended to be multinucleated, with low densities of population and built-over surfaces, and they tended to merge with surrounding agricultural landscapes in an urban–rural continuum. Perishable construction materials such as earth, wattle, and thatch were widely used for both domestic and public architecture.
