During the British colonial period a substantial young African population emerged in Dar es Salaam. Both colonial officials and African elders viewed this with dismay. They felt the resulting demoralisation of African youth posed a threat to both (African) authority and (colonial) order. However, measures aimed at addressing the ramifications of this phenomenon were mostly unsuccessful. Ironically, whilst British colonial policy aimed to keep African youth quiescent in rural, gerontocratic, tribal administrations, colonialism in fact provided the context in which both rapid urbanization and generational tension occurred. These continued to occur after independence; and it is argued that TANU politicians not only inherited the problems associated with the administration of the Tanganyikan capital, but that their responses were influenced by European and ‘elite’ African attitudes of the colonial era.
