Eastern Lunda
The Lunda people of the Luapula River valley in Zambia and DR Congo are called by others the Eastern Lunda to distinguish them from the 'western' Lunda people who remained in the heartland of the former Lunda Kingdom, but they themselves would use Kazembe-Lunda or Luunda with an elongated 'u' to make that distinction..
The Eastern Lunda migrated in the 18th Century to their current area under the leader Mwata Kazembe. Their neighbours in northern Zambia to whom they are allied, the Bemba, did so at the same time, and the Eastern Lunda took on the Bemba language in place of the Chilunda, their original language. Their Lunda compatriots in the North-Western Province of Zambia still speak Chilunda however.https://www.tandfonline.com/doi/abs/10.1080/00672700109511698?journalCode=raza20
