In a flurry of activity that peaked in the late 1950s, a cohort of activists from the region encompassing present-day Malawi, Zambia, Uganda and mainland Tanzania participated in a global landscape of anticolonial activism. They travelled to hubs like Delhi, London, Cairo and Accra, navigating Cold War internationalisms as students, exiles and political representatives. They formed committees, manned offices, published pamphlets, launched newsletters and corresponded with international organisations. And yet, often, their committees collapsed, they struggled with stationery shortages, their pamphlet manuscripts were rejected, their newsletters were prevented from reaching readers and they were let down by organisations. The introduction asks how to understand this story against a historiographical backdrop that narrates global anticolonialism through the violent hotspots of international decolonisation. It proposes a microspatial perspective and the conceptual framework of an anticolonial culture, arguing that this regional cohort, by some measures marginal, can help us understand the limits of transnational activism in the unfolding of decolonisation.
