Location of Tabora in Tanzania
Unyamwezi is a historical region in what is now Tanzania, around the modern city of Tabora to the south of Lake Victoria and east of Lake Tanganyika. It lay on the trade route from the coast to Lake Tanganyika and to the kingdoms to the west of Lake Victoria. The various peoples of the region were known as long-distance traders, providing porters for caravans and arranging caravans in their own right. At first the main trade was in ivory, but later slaving became more important.
