Kilwa Sultanate East African Trade Expansion

Timeline

1. 1361–1364Sofala · SofalaSultan Dawud ibn Sulayman, late in his second reign, continued monopolizing gold and ivory trade from the Zimbabwe Plateau via a governor at Sofala port and merchant agents. Kilwa's copper coins still circulated on the coast, and precious metals from Sofala were shipped via monsoon routes to Arab, Persian, and Indian markets, consolidating the sultanate's status as a key node in the Indian Ocean trade network.
2. 1364–1366Kilwa Kisiwani · KilwaAfter Dawud's death, Kilwa experienced a brief succession struggle: Husayn ibn Sulayman (al-Mat'un) launched raids into the African interior to obtain slaves and other trade goods, and Talut ibn Dawud and Sulayman ibn Dawud successively acceded. Political turmoil did not interrupt monsoon trade but exposed the sultanate's vulnerability in relying on force and agents to maintain commercial hegemony.
3. 1366–1370Zanzibar · ZanzibarAfter acceding, Sulayman ibn Husayn began a reign of over twenty years, integrating trade routes between island ports such as Zanzibar, Pemba, and Mafia and Kilwa island and Sofala. The sultanate continued using coral-stone port cities as nodes, exporting gold, ivory, slaves, and agricultural products, and importing Chinese porcelain, Persian glass, and Indian textiles; the trade pattern of the late 1360s laid the foundation for Kilwa's 15th-century zenith.
