Kilwa and the Swahili Coast (1640s)

Timeline

1. 1641–1644Kilwa Kivinje · TanzaniaSince Portuguese intervention in the sixteenth century, Kilwa's status as an Indian Ocean trade hub had steadily declined. In the early 1640s, port throughput and city-state revenues shrank further, and many merchants shifted to Mombasa and northern ports.
2. 1645–1648Swahili Coast · Swahili CoastCity-states such as Mombasa, Pate, and Zanzibar played more important roles in the coastal trade network. Swahili merchant communities maintained commercial ties with Gujarat and the Arabian Peninsula, with ivory, slaves, and cotton cloth remaining the principal commodities.
3. 1649–1650Zanzibar · ZanzibarMerchants and political forces from Oman gained increasing influence in places such as Zanzibar, laying the groundwork for the Omani Sultanate's conquest of the East African coast in the eighteenth century. Established city-states such as Kilwa were further marginalized in this transition.
