The Lulua people (var. Luluwa) are a Bantu-speaking ethnic group of the Lulua River valley in south central Kasai-Occidental province, Democratic Republic of the Congo, closely related to the Luba people. The Lulua are in fact a collection of small groups whose home bordered by the larger Luba state and the related Songye people and Chokwe people, with whom they share a very similar culture, history, and language.
Lulua lands are bordered on the south by other small ethnic groups, including the Mbagani, Lwalwa, Southern Kete, and the Salampasu. Rural Lulua remain mostly farmers.
The name Lulua seems to have appeared in the last quarter of the 19th century, previously these groups simply being ethnically Luba people outside the Luba (or Baluba) political structure. Georges Nzongola-Ntalaja, in his history of Congo, describes the history Lulua ethnicity as an invented ethnicity.
There is no better example of the invention of ethnicity or, in other words, of how artificial ethnic identities can be than the Lulua--Baluba conflict. [p.103]
In fact, the Lulua share language, matrilineal inheritance, and many other cultural traits with the Luba people and the Kondji or Luntu peoples. All three have been considered subgroups of the Luba, tracing their origins back to the Luba empire based in Katanga.
In the 19th century, the Chokwe—another related group—identified a disparate collection of neighboring farming and hunting groups in the area between the Upper and Lower Kasai and Lulua Rivers as the "Beena Luluwa" (singular, "Mwena Luluwa") meaning "people by the Luluwa." The powerful Luba empire in the 18th century helped push these small Luba hunting groups into their present home, according to oral sources, coming from the west. Their collective identity was limited to the institution of the "Kalamba", a judge and war leader to whom these small groups turned to in times of internal or external conflict. Nineteenth century European missionaries and travelers contributed to this process of ethnic differentiation from the Luba, defining these small communities in contradistinction to the states of their neighbors. Father A. Van Zandijcke, a Belgian missionary, reported that until 1870 there was no agreed collective name for the Lulua, with each kinship group or chieftaincy identifying themselves independently. By the first decade of the 20th century, the coming of Belgian colonialism along with pressure from the Luba empire and other neighbors, began to develop a Lulua collective identity.
