The Bantu Expansion stands for the concurrent dispersal of Bantu languages and Bantu-speaking people from an ancestral homeland situated in the Grassfields region in the borderland between current-day Nigeria and Cameroon. During their initial migration across most of Central, Eastern, and Southern Africa, which took place between approximately 5,000 and 1,500 years ago, Bantu speech communities not only introduced new languages in the areas where they immigrated but also new lifestyles, in which initially technological innovations such as pottery making and the use of large stone tools played an important role as did subsequently also farming and metallurgy. Wherever early Bantu speakers started to develop a sedentary way of life, they left an archaeologically visible culture. Once settled, Bantu-speaking newcomers strongly interacted with autochthonous hunter-gatherers, as is still visible in the gene pool and/or the languages of certain present-day Bantu speech communities. The driving forces behind what is the principal linguistic, cultural, and demographic process in Late Holocene Africa are still a matter of debate, but it is increasingly accepted that the climate-induced destruction of the rainforest in West Central Africa around 2,500 years ago gave a boost to the Bantu Expansion.

The University of Wisconsin-Madison has been a prominent producer of doctorates in African history since 1963. As of 2017 the institution had granted more than 110 degrees. Philip D. Curtin and Jan Vansina, both pioneers in launching the field, led the program until 1975 and were joined in 1969 by Steven Feierman. Together, they supervised an initial cohort of graduates, several of whom became leaders of the then still-formative field, particularly in its methodological infrastructure, as well as in economic and demographic history, slavery in Africa and the Atlantic slave trade, and medical history. The distinguishing features qualifying a diverse array of individual intellectual trajectories as a coherent “school” include a focus on epistemologically historical approaches anchored in the intellectual perspectives of Africans as historical actors and often also as they engaged broader commercial Atlantic and Indian Ocean and world contexts; smaller numbers of more recent doctorates had subsequently sustained these orientations. Former graduates of the program, William W. Brown, David Henige, and Thomas T. Spear, returned after 1975 to update this framework by bringing social theory and cultural history to bear on the African historical actors at the program’s core. Since 2005, a third generation of faculty members, Neil Kodesh, James Sweet, and Emily Colacci (all students of Wisconsin PhDs teaching at other institutions), have added contemporary approaches to the Wisconsin school’s continuing commitment to Africans’ distinctive epistemologies as they engaged the flows of modern global history. Professionally, Madison graduates have, accordingly, led the ongoing effort to bring Africa in from its initial marginality—as the continent seen as uniquely without a history—into the historical discipline’s core. An aphoristic summary of the Wisconsin legacy might be “Africans’ worlds and Africans in the world.”
