Olivette Otele explores how histories of transatlantic slavery impact on contemporary questions of migration Transatlantic slavery is a complex history of encounters between people of African and European descent. It is also a history of migrations, trade and subjugation. In this presentation, I look into the displacement of people from West Africa from the 17th to the 19th centuries. I ultimately aim at understanding how historians measure the impact of transatlantic slavery in Africa and its economic, social and cultural legacies. The presentation will consequently delve into Eltis’ and Lovejoy’s income per capita theories and explore Manning’s loss of workforce simulation model. It will then turn to histories of the territories from which Africans were captured by looking at the relationships amongst French and British traders, colonial administrators and local populations.
