Lydia Wilson Marshall's scholarship focuses on the archaeology of slavery, including slaving, emancipation, and self-emancipation. In her Ph.D. research, she investigated communities formed by runaway slaves in 19th-century coastal Kenya. After coming to Ã×À¼ÌåÓý, Marshall initiated a local research program about Putnam County’s so-called “Exodusters". The exodus of African Americans from the U.S. South in the late 1870s and early 1880s encompassed the relocation of tens of thousands of people to a variety of northern and western states, including Indiana. Most recently, she has undertaken a collaborative research project with Dr. Thomas Biginagwa (University of Dar es Salaam) at Kikole in southwestern Tanzania. Kikole was an early 20th-century entrepôt used in the trade of enslaved captives and ivory.
These research projects stem from a broader interest in the comparison of different systems of slavery, both between regions and across time. Marshall has explored this topic in depth in her edited books, "The Archaeology of Slavery: A Comparative Approach to Captivity and Coercion" (2015, SIU Press) and "Landscapes of Slavery in Africa" (2021, Routledge). She has additionally published her research in American Antiquity, Historical Archaeology, International Journal of Historical Archaeology, African Archaeological Review, and the Journal of African Archaeology, among other venues.
Her scholarship has been supported by grants from the National Science Foundation, the Social Science Research Council, the Fulbright-Hays Program, the Andrew W. Mellon Foundation, and the American Council of Learned Societies. She received the 2018 John L. Cotter Award for excellence in early career scholarship from the Society for Historical Archaeology.
