The prehistory of Botswana concerns the sophisticated environmental knowledge, economic strategies, and social networks of the hunter-gatherer, pastoralists, and agropastoralist communities that have called Botswana home. Diverse subsistence strategies and societal structures ranging from heterarchical to hierarchical have coincided and responded flexibly to climate and environmental variables. Botswana has also played a central, but often overlooked, role in precolonial trade within the interior of Africa and across the Indian Ocean.
Botswana contains well-preserved archaeological records for the Middle Stone Age, Late Stone Age, and Iron Age periods, including one of the highest concentrations of rock art in the world at Tsodilo Hills. The prehistory of Botswana extends over 100,000 years and includes successful, innovative, and adaptive occupations in a wide variety of environmental zones, from the Okavango Delta to the Kalahari sandveld, and better-watered hardveld areas in the east. Stone Age peoples adapted to both arid and wet lands, and the archaeological record includes early evidence for freshwater fish exploitation. Hunting with bone points dates to 35,000 years ago, with additional evidence for poisonous, reversible arrowheads between 21,000 and 30,000 years ago. Evidence for ritualized behavior through rock paintings, rock carvings, and the intentional destruction and abandonment of stone tools at Tsodilo Hills provides further insights to the social dimensions of early peoples. In the Iron Age, hunter-gatherer communities and agropastoralists participated in a regional and later protoglobal trade across the Indian Ocean for a thousand years before European involvement; as the regional economy intensified, large polities such as Bosutswe and even kingdoms such as the Butua state emerged, controlling access to resources such as game, ivory, salt, specularite, and gold. In the modern era, the historical archaeology of sites such as Old Palapye (Phalatswe) provide additional insight to historical documents that can contradict Eurocentric understandings of Botswana’s past.
