The first evidence of inhabitation is in the seventh century AD at a site called Tumbe in Micheweni District of the island.
[2] Towns continued to be founded around the island after Tumbe, and agricultural and ceramic artifacts show the people were farmers.
[1] The archaeobotanical evidence from Tumbe and the surrounding areas point to an agriculture system focused on pearl millet.
Rice, legumes, coconut and other tree nuts were found to have been important contributors to the agricultural economy.
Archaeological surveys show that the stonetown of Chwaka started as a small village and grew into a large, densely populated town.

The Periplus also notes that the Greeks, and other traders, would trade with the island for ivory, tortoise shell, rhinoceros horn, palm oil, cinnamon, frankincense, and slaves.
In return, the people on Pemba would receive awls, glass, wheat, wine, daggers, and hatchets.
Artifacts that support this data include pottery and glass from Asia, China and Europe as well as ochre linked to mainland Africa.
[2][4] Archaeological research on Pemba and throughout the Swahili coast has long been focused on sites with visible stone structures.
