Swahili Maritime Trade

Timeline

1. 800–999Early trading settlements on the East African coast · KenyaArchaeological sites show that fishing and trading settlements facing the Indian Ocean had already appeared on the East African coast, with local vessels and foreign merchants conducting seasonal near-shore exchange, laying the foundation for later city-state maritime transport.
2. 1011–1020Kilwa (Kilwa Kisiwani) · Lindi RegionIn the early 11th century, Swahili city-states such as Kilwa organized ocean-going fleets based on monsoon patterns, exchanging gold, ivory, and aromatics for West Asian and South Asian goods, with maritime trade routes becoming increasingly fixed and large-scale.
3. 1100–1499Indian Ocean route network · Arabian SeaArab lateen dhows plied East Africa, the Red Sea, the Persian Gulf, and India's west coast in keeping with the monsoon cycle; Swahili ports became shipping hubs of the western Indian Ocean, with very active circulation of porcelain and coins.
4. 1500–1700Mozambique Channel · MozambiqueAfter European colonial powers controlled key ports and routes, the maritime advantages of traditional Swahili city-states declined, and the focus of Indian Ocean trade gradually shifted toward a European-dominated ocean shipping system.
