Mombasa

Al-Idrisi (1154) describes Manbasa as a small town (bulayda) of the Zanj on the sea, on the shore of a great inlet that ships ascend for two days, its banks uninhabited and full of game; its people mine and smelt iron and hunt leopards, and keep red dogs that overcome wild beasts; here lives the king of the Zanj, whose soldiers go on foot for horses cannot live in their land.

Mombasa's own traditions speak of a pre-Islamic queen, Mwana Mkisi, founder of Kongowea, the first town on the island, whose lineages head the Twelve Nations (Thenashara Taifa), and of Shehe Mvita, a Muslim scholar who displaced her line and built the first stone mosque; neither is dated. The oldest standing mosque (Mnara) is of about 1300. In 1200 Mombasa is a small town on the island, probably still the seat of a Zanj king, its Islam not attested.

  • The Kilwa Chronicle (Arabic version about 1520 to 1530; Portuguese summary printed by João de Barros in 1552). The only narrative for the Swahili coast before the Portuguese, in two versions that agree on the dynasty and disagree on much else: the arrival of Ali ibn al-Hasan from Shiraz, his purchase of the island, and the line of his descendants, with reign lengths that put Sulayman ibn al-Hasan, Dawud ibn Sulayman, Talut and Husayn ibn Sulayman in the decades around 1200 (Bosworth's conversion gives Husayn about 1191 to 1215), the winning of Sofala's gold trade, and later the Mahdali dynasty of Abu'l-Mawahib.

  • The Travels of Ibn Battuta: Egypt, the Horn, the Swahili coast and Mali, Ibn Battuta (dictated to Ibn Juzayy) (1355, at Fez). A century and a half late, but the first eyewitness of places that in 1200 are known only from hearsay: Zeila and its stench, Mogadishu with its sultan, qadi and merchant hosts, Mombasa, and Kilwa under the Mahdali sultan Abu'l-Muzaffar al-Hasan, raiding the Zanj of the mainland; and the Sahara road from Sijilmasa through Taghaza and Walata to the court of Mali under Mansa Sulayman, then Timbuktu, Gao and Takedda among the veiled Berbers.
