Although usually associated with events in Europe and North America, the events of the ‘global 1968’ were global in scope. This chapter shows how Tanzanian youths shared common ground with their contemporaries around the world in protesting against Cold War interventions in Vietnam and Czechoslovakia. In doing so, they drew inspiration from the landscape of radical ideas and texts of revolutionary Dar es Salaam. But in contrast to the dynamics of counter-hegemonic protest elsewhere, the Tanzanian government’s foreign policy meant that it could channel these radical critiques of superpower imperialism into its own nation-building project. The language of anti-imperialism could also be deployed against more immediate threats, as the case of Malawi’s claims to Tanzanian territory demonstrate. While recognising the significance of transnational Afro-Asian and Third Worldist solidarities in these movements, the chapter integrates these dynamics into a national story. The state circumscribed the autonomy of youth activism, especially when it risked upsetting Julius Nyerere’s carefully calculated foreign policy.
