Inspired by current studies that underscore the limits of imperial power over the colonized, the proposed research seeks to demonstrate the centrality of Lunda medical auxiliaries in the construction of missionary medicine in Zambia’s Mwinilunga District between 1890 and 1964. The project hypothesizes that although Brethren missionaries who worked in the district perceived such auxiliaries as allies in the combat against local healing systems, Lunda medical employees were at the center of foraging medical hybridity, and read their own meanings into mission medicine. They also, the hypothesis continues, provided the agency through which Lunda medicine itself appropriated some elements of the Euro-Christian version of biomedicine. This project will examine how this ambiguous position of the auxiliaries, alone with changing disease patterns in the district, influenced social and working relations between Lunda medical auxiliaries and their Brethren employers.
