The life of Ayuba Sulayman Diallo (also known as Job ben Solomon) receives a fresh examination in this article, based primarily on his own writings. The son of an Imam from Bundu in Senegambia, Diallo was enslaved in 1731 and transported to America. He survived to gain his freedom, make his mark in London society, and return to Africa in 1734. This article offers an analysis of documents from the British Library, including items that have not been previously analysed and are here translated into English for the first time. In addition, they bring together what is known of his archive, including the letters he wrote before, during, and after his time in London, the Qur'ans he scribed there, and the scraps and snippets created as he discussed the Arabic language with friends.

A close analysis of Diallo's writings reveals new information about his life history; his relationships with the elites in both Bundu and London; his scholarly abilities; and the history of Bundu itself. Diallo used the technology of writing to direct the course of his own life and career, converting a disastrous course of events into favourable opportunities for himself.

Migration was a crucial component of the spatially uneven formation of labour markets and export-oriented economies in colonial Africa. Much of this mobility was initiated by migrants themselves rather than by colonial authorities. Building on analytical concepts from economic history and migration theory, this study explains the changing composition and magnitude of one such uncontrolled migration flow, from Ruanda-Urundi to Buganda. Migrants’ mobility choices – when to migrate, for how long, and with whom – proved highly responsive to shifting economic opportunity structures on the sending and receiving ends. Initially, large differences in terms of land and labour endowments, socio-economic structures, and colonial interventions, combined with substantial scope for price arbitrage, created large spatial inequalities of opportunity and strong incentives for circular male labour migration. Over time, however, migration contracted as opportunities in Ruanda-Urundi and Uganda converged, not in the least as a result of large-scale mobility itself.

This article reconstructs the trajectory of the Kwame Nkrumah Ideological Institute (KNII) to shed light on the politics of socialist education in 1960s Ghana. On the basis of archival evidence, it explores the changing role of the institute in the making of Nkrumahism as public discourse and documents the evolving relationship between the universalism of Marxism-Leninism and the quest for more local political iconographies centred on Nkrumah's life and work. Secondly, the article analyses the individual motivations and experiences of a sample of foreign lecturers. The article suggests that ideological institutes offer insights into the processes by which official ideologies were created and disseminated, a foil through which to interrogate the usages and appropriation of social sciences education, and a window onto the multiple ways in which local and foreign agents negotiated their identities and political participation in African socialist experiments.

Throughout the socialist experiment between 1974 and 1992, the Mozambique Liberation Front (Frelimo) ran a network of internment camps officially known as reeducation centers. Established in remote rural sites to mentally decolonize wayward members of urban society and putative enemies of the socialist revolution, the camps became a dumping ground for unwanted citizens accused of all kinds of wrongdoing. Although the Frelimo leaders envisioned a pedagogical institution that would undo the damage of colonialism by transforming reeducatees into new social beings, the gap between the idea of rehabilitation and the reality of detention was abysmally wide. Austerity – the order of the day throughout the fifteen years of socialist experiment in Mozambique – conditioned and defined the organic functioning of reeducation camps. Unlike internment camps elsewhere, Mozambique's camps were not strictly regimented. The carceral regime that emerged not only set Mozambique's reeducation centers apart from camps elsewhere, they were also far from the technocratic moralism and panoptic ambitions of the ruling party.

This article examines the role of trade unions and of the Kebele – the most local urban administrative structures of the Ethiopian state – in the making of the Red Terror, a period of unprecedented political violence that closely followed the Ethiopian revolution of 1974. Drawing on a broad range of new source materials – from labour union files to oral histories and East German State Security archives – this article shows how the Red Terror was in large part the product of synergies between diverse groups and actors within these structures, and how it was rooted in histories, motives, and collaborations that have scarcely been considered in the historiography of revolutionary Ethiopia. In turn, the Red Terror radically reshaped both trade unions and Kebele administrations, affording Ethiopian state actors an unprecedented means of control over civil society and urban residents.
