Port · Kilwa under its Shirazi sultans, with Mafia · as at first light, 1 January 1200

Kisimani Mafia

The old town of Mafia on Ras Kisimani at the western point of the island, looking across the channel to the Rufiji delta, occupied from the tenth century to the fifteenth.

Chittick excavated it in the 1950s and 1960s: the earliest mosque levels go back to the tenth and eleventh centuries, Kilwa coins of Ali bin al-Hasan were found, and he judged Mafia of equal importance with Kilwa at the time of the Shirazi arrival. Much of the site has since been eaten by the sea. On 1 January 1200 it is the island's main town, probably ruled for or by the Kilwa house.

Primary sources for Kilwa

Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.

  • 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 coins of Kilwa and the early Swahili inscriptions (coins struck from about the eleventh century; dated inscriptions from 1107). The only contemporary writing from the coast around 1200.
  • 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.

  • The History of the Observant Traveller: the pages on Zeila, Berbera, Mogadishu and Dahlak, Ibn al-Mujawir (Yusuf ibn Yaqub ibn al-Mujawir) (about 1221 to 1230). The closest description of the Horn's ports to 1200, written about twenty-five years later by a trader and official who worked the Aden trade: Zeila and its traffic in slaves, ivory and the goods of the Ethiopian interior; the Barbar (Somali) coast with Berbera and Mogadishu, and the sea route from Aden to Mogadishu and on to Kilwa with its sailing seasons; the Dahlak islands with their own sultan and his dues; Socotra; and the customs and prices of Aden under the Ayyubids of Yemen.
