The South African interior, roughly equivalent to the Highveld on the southern continental plateau, was in the 19th century a stage of numerous players and groups, acting in concert and in conflict with one another, as often dissolving as taking on board new members. The fortunes of Highveld inhabitants, occupiers, and passers-by fluctuated without periods of calm, and turned advantages to few. It was therefore not uncommon for the human flotsam and jetsam created by raiding, battles, and migrations, aggravated by drought and famine, to be subordinated by the survivors and forced to serve those with whom they had no prior allegiance or knowledge. Slavery in the interior was largely a by-product of staking out territory. Rather than generate slaves for sale in an external market, slavery on the Highveld was fed by the political impulse to aggregate followers and servants. An internal exchange emerged in some areas, and traders made a few transactions with coastal exporters, but the general pattern of enslavement was acquisition by raiding and distribution among raiders. The majority taken were youngsters and, to a lesser degree, women. As a rule, the menfolk were killed.
The Soninke are an ancient West African ethnicity that probably gave rise to the much larger group that is called the Mande of which the Soninke are part. The Soninke language belongs to the northwestern Mande group but through the dynamism of its speakers has loaned many words and concepts to distant ethnic groups throughout the West African ecological zones. Mande groups such as the Malinke and Bambara may be descendants of the Soninke or a Proto-Soninke group. The Soninke are the founder of the first West African empire, Ghana, which they themselves call Wagadu, from the 6th to the 12th centuries
