Long-distance exchange networks played key roles in the socio-political history of Central Africa before the 20th century, but they are poorly known prior to the 19th century owing to a scarcity of written sources covering the earlier centuries. Archaeological data, however, suggest that major 19th-century trade routes were well established several centuries before.

Around 1,200 years ago, archaeological evidence suggests pre-existing pastoralist societies that had been present in some parts of eastern Africa since c. 5,000 BP experience significant cultural and economic change. Materials signs of these include the uptake of iron smelting technologies, new ceramic styles, and changes in food production. In the following centuries, the region also experienced several significant shifts in climate, alternating between periods of increased rainfall and extended droughts.
