The struggle in the Gt. Lakes region is between poverty and wealth
I have defined the Great Lakes region to include southwest Uganda (former Ankole and Kigezi districts), Burundi, Eastern DRC (North and South Kivu) and Rwanda. Since interaction between the two ethnic groups of Bantu and Nilotic peoples, the region has been characterized by ethnic conflicts of so-called Bantu agriculturalists and Nilotic (Tutsi) pastoralists. Bantu designation of all people in southwest Uganda is a linguistic convenience because Bairu and Batutsi are ethnically very different. Tutsi are Nilotic people that originated in South Sudan (not Ethiopia as originally thought) home also of Nubians, Acholi and Dinka, etc. Bairu and Bahutu are Bantu people that originated in the Cameroon and Nigeria border.
The Nilotic pastoralists or Batutsi entered the region around the 15th or 16th century poorer and less civilized than the Bantu people they found there. They adopted Bantu language, names and culture (the Tutsi title of mwami or king was originally Hutu’s). Batutsi resisted intermarriage with Bantu people: occasionally a prominent Mwiru or Muhutu man would be given a Tutsi woman to marry and then the man would be tutsified and join the social Batutsi club as a junior partner and abandon his ancestral people thus depriving Bantu of capable leaders. This was a tool of Tutsi dominating non-Tutsi people. These were politically-induced and arranged marriages, not through love. Batutsi have many distinct characteristics.
