In this episode Rebecca Grollemund (Missouri) and David Schoenbrun (Northwestern) join editor Marissa Moorman (Wisconsin) to discuss recent insights and the continuing complexity of classifying five millennia of Bantu language expansions using statistics, computational methods, and other tools. In the wide-ranging conversation, the authors make a powerful case for the utility of collaborative, multidisciplinary, and multigenerational scholarship, talk about the need to bring an eye for contingency to the big questions still surrounding the so-called Bantu-migration, and recount the joy and passion which the late Jan Vansina brought to this project and his scholarship in general. Grollemund, Schoenbrun, and Vansina’s open access article, entitled ‘Moving Histories: Bantu Language Expansions, Eclectic Economies, and Mobilities’, features in the March 2023 issue of the JAH. *For a sampling of further works on Bantu language expansions and related social histories, see: C.
