Ras Mkumbuu in 1200, Swahili towns

A town at the end of the Mkumbuu peninsula west of Chake Chake, with a large mosque that was for a time the largest on the coast south of the Sahara, pillar tombs and houses; occupation from the ninth century to its abandonment in the sixteenth.

Kirkman proposed it was al-Mas'udi's Qanbalu, the Muslim island town of the Zanj in the tenth century; whether Qanbalu is Ras Mkumbuu or Pemba as a whole is still debated. Later excavation shows a first town of about 6 hectares in the tenth to twelfth centuries: a timber mosque burnt and rebuilt in coral in the late tenth century, and by the eleventh some fifteen coral houses, a larger mosque and a cemetery of pillar tombs, a merchant town with trade links of its own. On 1 January 1200 it is a stone merchant town at the end of that first phase (Kirkman had found nothing earlier than the thirteenth century).

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.
