The Kilwa Chronicle is a text, believed to be based on oral tradition, that describes the origins of the Swahili city-state of Kilwa, located on an Indian Ocean island near the East African coast.
It recounts the genealogy of the rulers of the Kilwa Sultanate, following the foundation of the city by Persians from Shiraz and Hormuz in the tenth century until the arrival of the Portuguese in the sixteenth century.
[1] Subsequent ancient DNA[2] studies have confirmed much of the basis of these stories to be true.
[4] Two sources of the Chronicle exist: the Kitāb al-Sulwa in Arabic and a Portuguese version that is a section of the book Décadas da Ásia by the historian João de Barros.
[1] The genealogical account is similar in both versions, but other details vary substantially.
