Claim: The Nilotic languages are spoken by the Luo peoples.

Nilotic peoples are peoples indigenous to the Nile Valley who speak Nilotic languages ; this is a large sub-group of the Nilo-Saharan languages spoken in South Sudan , Uganda , Kenya , and northern Tanzania . In a more general sense , the Nilotic peoples include all descendants of the original Nilo-Saharan speakers . Among these are the Luo , Sara , Maasai , Kalenjin , Dinka , Nuer , Shilluk , Ateker , and the Maa-speaking peoples , each of which is a cluster of several ethnic groups .   The Nilotes constitute the majority of the population in South Sudan , an area that is believed to be their original point of dispersal . After the Bantu peoples , they constitute the second-largest group of peoples inhabiting the African Great Lakes region around the Eastern Great Rift . They make up a notable part of the population of southwestern Ethiopia as well .   The Nilote peoples primarily adhere to Christianity and traditional faiths , including the Dinka religion .
