Around 1500, a small group of Luo known as the Biito-Luo led by a Chief called Labongo whose full title became Isingoma Labongo Rukidi (sometimes named as Mpuga Rukidi), encountered Bantu-speaking peoples living in the area of Bunyoro. These Luo settled with the Bantu and established the Babiito dynasty, replacing the Bachwezi dynasty of the Empire of Kitara. Labongo, the first in the line of the Babiito kings of Bunyoro-Kitara, was according to Bunyoro legend the twin brother of Kato Kimera, the first king of Buganda. These Luo were assimilated by the Bantu, and they lost their language and culture.
Later in the 16th century, other Luo-speaking people moved to the area that encompasses present day Southern Sudan, Northern Uganda and North-Eastern Congo (DRC) – forming the Alur, Jonam and Acholi. Conflicts developed when they encountered the Lango who had been living in the area north of Lake Kyoga. Lango also speak a Luo language. According to Driberg (1923), Lango reached eastern province of Uganda (Otuke Hills) having traveled southeasterly from the Shilluk area, and that Lango language is similar with that of the Shilluk language. Lango people identify with the Luo peoples, refuting the Ateker connection.
Between the middle of the 16th century and the beginning of the 17th century, some Luo groups proceeded eastwards. One group called Padhola (or Jopadhola - people of Adhola), led by a chief called Adhola, settled in Budama in Eastern Uganda. They settled in a thickly forested area as a defence against attacks from Bantu neighbours who had already settled there. This self-imposed isolation helped them maintain their language and culture amidst Bantu and Ateker communities. Those who went further a field were the joka jok and joka owiny.the jok luo moved deeper into the kaviirondo gulf and are the present day jo kisumo and jo Rachuonyo amongst others.Jo owiny occupied an area near got ramogi or ramogi hill in alego of siaya district.the owiny's ruins are still identifiable to this day at bungu owiny near lake kanyaboli.The other notable luo group is the omolo luo who inhabited ugenya and gem areas of siaya district.The last immigrants were the jo Kager who are related to the omollo luo and their leader was ochieng waljak ger a formidable leader who with advanced military skill drove a way the omiya or bantu tribes who were then living in present day ugenya around 1750AD
