The hyphenated category Lunda-Chokwe constituted an estimated 8 percent of the Angolan population in 1988. As the hyphenation implies, the category comprises at least two subsets, the origins of which are known to be different and the events leading to their inclusion in a single set are recent. The Lunda alone were a congeries of peoples brought together in the far-flung Lunda Empire (seventeenth century to nineteenth century) under the hegemony of a people calling themselves Ruund, its capital in the eastern section of Zaire's Katanga Province (present-day Shaba Province). Lunda is the form of the name used for the Ruund and for themselves by adjacent peoples to the south who came under Ruund domination. In some sources, the Ruund are called Northern Lunda, and their neighbors are called Southern Lunda. The most significant element of the latter, called Ndembu (or Ndembo), lived in Zaire and Zambia. In Angola the people with whom the northward-expanding Chokwe came into contact were chiefly Ruund speakers. The economic and political decline of the empire by the second half of the nineteenth century and the demarcation of colonial boundaries ended Ruund political domination over those elements beyond the Zairian borders.
