Luba-Katanga language
Luba-Katanga, also known as Luba-Shaba and Kiluba, is one of the two major Bantu languages spoken in the Democratic Republic of the Congo called "Luba". It is spoken mostly in the south-east area of the country by the Luba people.
Kiluba is spoken in the area around Kabongo, Kamina, Luena, Lubudi, Malemba Nkulu, Mulongo, and Kaniama, mostly in Katanga. Some 500 years ago or more, the Luba Kasai left Katanga and settled in the Kasai; since then, Luba Kasai has evolved until it is no longer mutually intelligible with Luba Katanga.
