In the western part of Zambia, another Southern African group of Sotho-Tswana heritage called the Kololo manage to conquer the local inhabitants who were migrants from the fallen Luba and Lunda states called the Luyana or Aluyi. The Luyana established the Barotse Kingdom on the floodplains of the Zambezi upon their arrival from Katanga. Under the Kololo, the Kololo language was imposed upon the Luyana until the Luyana revolted and overthrew the Kololo by this time the Luyana language was largely forgotten and a new hybrid language emerged, SiLozi and the Luyana began to refer to themselves as Lozi.
