Lourenço Marques explores Delagoa Bay

In 1544 a Portuguese expedition associated with Lourenço Marques and António Caldeira explored Delagoa Bay and the river systems opening into it. The bay lies north of present-day South Africa and was already a settled coastal region with its own communities, production and exchange relationships. Portuguese interest arose from the wider Estado da Índia network, whose merchants sought harbours, provisions, ivory, gold and access to inland routes.

The expedition extended Portuguese maritime knowledge of the south-eastern African coast. The available evidence supports exploration and commercial interest more securely than a formal survey or permanent settlement. Later Portuguese, Dutch and other commercial and political activity in the bay belongs to subsequent periods. Marques’s expedition belongs to the same expanding maritime world as the Portuguese posts at Sofala and Mozambique Island, while remaining distinct from their fortified settlements.

Significance

The voyage placed Delagoa Bay more firmly within Portuguese navigational and commercial knowledge and helped make the bay a recurring point of contact between Indian Ocean shipping and the societies of the south-eastern African interior.
