The Lozi people are an ethnic group who inhabit present-day Zambia, Botswana, Angola and Namibia. The main function of Lozi mythology is to show that the original Lozi people (the Luyi or Luyana) were dwellers on the Barotse Floodplain of the upper Zambezi River and that they are, therefore, entitled to claim unchallenged title to that homeland. Secondly, Lozi mythology gives legitimacy to the Lozi kingdom's foundations, by linking the monarchy and the people to a creator god, whom the Lozi call Nyambe.
