In the latter half of the nineteenth century, a change came about in the hereditary régime of the Bemba kingdom during civil strife between members of the kingdom's royal and noble strata. The rulers of the kingdom, who shared in the Central African trade of slaves and ivory for guns and calico, fought to defend their positions and to meet the competition from opponents who could enter into new relations of power. Past conceptions of the kingdom in terms of centralization have obscured this, hindering understanding of the specialized structures of authority among royals and nobles, the differences among the ruling strata, and the variable interlocking of their federal administrations. Richards has argued, in somewhat contradictory fashion, that the kingdom, primarily unified through ritual beliefs, was nevertheless centralized owing to an apparent concentrating of control over territorial administration in the hands of royals:
In Northern Rhodesia the kingdom of the Bemba was kept united by the strong belief of the people in the ritual powers of their king. All district chieftainships were filled by princes of the blood who moved in succession by genealogical seniority from one chieftainship to another. Clan leaders were unimportant politically and the king's favourites never held office. A royal dynasty in control of all territorial posts seem to have been sufficient to achieve centralization of a loose type.
