Balunda

The Lunda (Balunda, Luunda, Ruund) originated in what is now the Democratic Republic of the Congo along the Kalanyi River and formed the Kingdom of Lunda in the 17th century under their ruler, Mwata Yamvo or Mwaant Yav, with their capital at Musumba. From there they spread widely through Katanga and into Eastern Angola, north-western Zambia (the Kanongesha-Lunda and the Ishindi-Lunda) and the Luapula valley of Zambia (the Eastern Lunda or Kazembe-Lunda).

The Lunda were allied to the Luba, and their migrations and conquests spawned a number of tribes such as the Luvale of the upper Zambezi and the Kasanje on the upper Kwango River of Angola. Today the Lunda people comprise hundreds of subgroups such as the Akosa, Imbangala and Ndembu, and number approximately 500,000 in Angola, 750,000 in the Congo, and 200,000 in Zambia. Most speak the Lunda language, Chilunda, except for the Kazembe-Lunda who have adopted the Bemba language of their neighbours.

The Lunda people's heartland was rich in the natural resources of rivers, lakes, forests and savannah. Its people were fishermen and farmers, and they prospered. They grew maize, millet, yams, sorghum, squash, beans, sweet potatoes, oil palms and tobacco. Their traders came into contact with the Portuguese, and Arab and Swahili traders of East Africa. They played a large role in the slave and ivory trade that moved goods and people from central Africa to the coasts for export.
