My dissertation explores the “politics of mobility” over the course of Kenya’s colonial and postcolonial histories. Moving between the technopolitical strategies of the state and the quotidian practices of Kenyans, I consider how technologies of mobility have mediated social relationships, turning movement itself into a contested category of political action. In doing so, I track how colonial and postcolonial authorities have used road networks, the rights to mobility, and the circulation of the technologies associated with roads – bicycles, motorcycles, cars, and matatus (minibuses) – to reward “loyal” constituencies, thereby variously marking inclusion and exclusion from popular though contested visions of “development” and “modernity.” Combining the insights of cultural studies and anthropology, with those of science studies, this research both tracks how the material and infrastructural routes of colonial and post-colonial governance have been used to extend coercive authority and, concomitantly, how these technologies have been appropriated by populations, becoming rich idioms as well as central material sites for popular expressions of discontent. To this end, this dissertation explores how roads are used as a central organizing theme in Kenyan discussions of the relative “development” of the country, discussions that popularly express regional understandings of the deprivations associated with state and everyday forms of corruption.
