Western Bantu Expansion

Abstract

Linguistic studies are now advanced enough to allow us to sketch how Central Africa was settled by farmers who spoke western Bantu languages. From the second millenium B.C. onward, yarn-growers with neolithic tools spread in the rain-forests of the Cameroons. By adapting repeatedly to different environments they expanded over the whole forest area and also over the savannas and woodlands further south. These people were in search of optimal environments, quite willing to move to settle in favoured locales. Although they multiplied there, their expansion over such huge areas meant that their settlements remained very thinly scattered over Central Africa.A thickening of settlement would only occur when new crops – the banana in the rain-forest, cereals in more open lands – allowed farmers to settle in most places. Iron-smelting was less important here than these new crops. These induced further population growth, densities rose and movements in search of the best unknown lands ceased. If the first settlement had only moderately inconvenienced the autochthones, the thickening of population led in time to their absorption, dependence on villagers, or emigration in search of ever-decreasing empty areas.
