This article analyzes the relationship between masculinity and domestic service by exploring how servants resisted the changing culture and realities of their work in colonial Dar es Salaam, the capital of British colonial Tanganyika. Domestic servants formed nearly half the working class in the city, and ninety-seven percent of servants were African men. Considered during the early decades of colonialism to be a well-paid, skilled, and respectable occupation, domestic service transformed in the 1940s and 1950s, due to the World War II economic crisis, soaring urban population, and introduction of new labor regulations. The primary threats to servants’ masculinity during the latter half of the colonial era were the growing limitations the occupation placed on men's abilities to achieve the financial and social capital required to achieve senior status and respect within their families and the African community. In response to rising exploitation and declining wages, servants formed Tanganyika's first African labor union.
