Unyamwezi

[2] The Encyclopædia Britannica Eleventh Edition said the region "is rich in woods and grass, and has many villages surrounded by well cultivated farms and gardens.

There are records of Sultan Sayyid Said of Zanzibar negotiating with envoys from Unyamwezi in 1839 for safe passage for caravans to the interior.

Slaves brought from the Congo Basin or the Great Lakes region would be held at Tabora, then sent down to the coast in small groups for onward shipment.

[7] The first Europeans to reach the region were Richard Francis Burton and John Hanning Speke, who had been sponsored by the Royal Geographical Society and the British government to investigate the great Lake Uniamési said by German missionaries to lie in the region and determine if it was the source of the Nile.

[10] At Kazeh Burton and Speke found a mixed population of Nyamwezi, Tutsi and Arabs engaged in cattle farming and cultivation of foods such as rice, cassava, pawpaw and citrus.
