Kilwa Kisiwani, just off the southern coast of today’s Tanzania, was one of many trading ports along Africa’s east coast, but for a while it was the most powerful. Between the thirteenth- and the fifteenth-centuries CE, a Muslim sultanate was established here, founded by a group of explorers coming from the city of Shiraz in today’s Iran. They established themselves as a ruling class and imposed their own culture and values on the community. In the fifteenth-century the sultanate controlled Malindi, Mombasa, Pemba, Zanzibar, Comoro and Sofala, as well as ports on the island of Madagascar. Kilwa Kisiwani was famous for its fort which served as a residence for the sultan but also as a place of trade. The residence had over one hundred individual rooms, reception halls, wide staircases and an octagonal swimming pool. Kilwa’s other main attraction was its mosque, constructed entirely out of coral stone. Ibn Battuta, who came here in 1331, was highly impressed with the way the city was laid out and with the generosity and religiosity of its ruler.

By the time of Ibn Battuta’s visit, Kilwa had already been engaged commerce for some thousand years. Already the Periplus of the Erythraean Sea, a Greek manual for merchants compiled in the first century CE, mentions the ports along the eastern coast of Africa as excellent places to buy ivory and tortoise shell. Coins minted in Kilwa have been found in Great Zimbabwe, Oman and even Australia.
