Lecture by Décio Muianga & Diogo Oliveira: Mozambique’s coast is marked by different cultural horizons that span from hunter-gatherers to the establishment of Bantu farmers and later proceeded by Swahili trade settlements that were interconnected within the Indian Ocean Trade Network. New perspectives from archaeological (terrestrial and maritime), historical and anthropological research are bringing to light a complex body of knowledge about slavery in this section of southern East Africa, which has been based chiefly on Portuguese sources (customs, colonial administration archives, etc.). This exclusion of indigenous and Swahili sources has left gaps relevant to the understanding of this process. It is then critical to look at different sources to better comprehend the complex past slave trade activities and their impacts on Mozambique.
