Tanzania, and the central position of the Nyamwezi in the regional trading
system, all became key factors leading to the rise of the caravan system."$ The
Nyamwezi were essentially cultivators, producing, among other crops,
grains, pulses, potatoes, pumpkins and tobacco. But because Unyamwezi is
somewhat more forested than neighbouring territories, inhabitants were able
to harvest forest products such as honey, to make baskets and wooden
utensils, and to hunt wildlife. Lacking iron ore and good quality salt, the
Nyamwezi exchanged their products for Sumbwa and Konongo iron, and
salt from the Uvinza pans. Other neighbours, especially the Gogo, Sukuma
and Ha, kept large cattle herds. The Nyamwezi exchanged their grain, bark
cloth, honey and other products for the cattle and hides of herders. The
fortuitous position of the Nyamwezi in the centre of the regional trading
system of western Tanzania made them ideal intermediaries. Moreover, the
organization of the gender division of labour, the absence at first of large
herds of cattle, and the utilization of immigrant Tutsi and slave labour,"% left
them free to travel during the dry season when there was little work in the
fields. In contrast, the nature of the local economies of other peoples in
central and western Tanzania made it impossible for large numbers to be
absent at any one time.
The geographical location of Unyamwezi became even more important
when the main routes to and from the coast shifted during the s from the
Ruaha river line to the central route network through Ugogo and
Unyanyembe."& Location is inadequate in itself to explain the central role of
the Nyamwezi, but other trading peoples including the Yao, Swahili and the
Kamba, were all based in strategic positions for the caravan trade.
A secondary factor that may have encouraged long-distance travel and
caravan porterage was the prevailing condition of lengthy peace and
stability."' There is no evidence for attacks by outsiders until the mid-
nineteenth century, when parts of Ukimbu, Unyamwezi and Usumbwa were
invaded by the migrating Ngoni."( Prior to this, conflict was limited to
occasional small-scale raiding of one Nyamwezi chiefdom by another. In
