This article outlines some aspects of the history of West Africans in Britain during the colonial era in the first half of the twentieth century. In particular it focuses on the emergence of West African nationalism in Britain and highlights some of the political activities of those African sojourners abroad, who were also temporarily part of the diaspora. Their political organizations, especially the West African Students' Union and the West African National Secretariat, were influential in West Africa and throughout the diaspora and reflected changing political identities, consciousness, and historical conditions. Most important, they show that West Africans developed and maintained their own distinctive political aims, consciousness, and ideologies, while at the same time contributing to and being influenced by those of the diaspora. These aims and ideologies also reflected the particularities of political and social conditions in Britain, conditions that were shaped by the African presence itself. West African nationalism provided a distinctive philosophy and orientation even for West Africans' pan-African activities. Indeed they saw the future of Africa and the diaspora as determined by political and other advances in the West African colonies.
