This partly reflected internal Belgian domestic politics, in which the discrimination against the Hutu majority came to be regarded as similar to oppression within Belgium stemming from the Flemish-Walloon conflict, and the democratization and empowerment of the Hutu was seen as a just response to the Tutsi domination. Belgian policies wavered and flip-flopped considerably during this period leading up to independence of Burundi and Rwanda. The Hutu majority in Rwanda had revolted against the Tutsi and was able to take power. Tutsis fled and created exile communities outside Rwanda in Uganda and Tanzania.
Origins of Hutu, Tutsi and Twa largely of Bantu extraction (60% E1b1a, 20% B, 4% E3). Paternal genetic influences associated with the Horn of Africa and North Africa are few (under 3% E1b1b), and are ascribed to much earlier inhabitants who were assimilated. However, the Tutsi have considerably more haplogroup B paternal lineages (14.9% B) than do the Hutu (4.3% B). Trombetta et al. (2015) found 22.2% of E1b1b in a small sample of Tutsis from Burundi, but no bearers of the haplogroup among the local Hutu and Twa populations. The subclade was of the M293 variety, which suggests that the ancestors of Tutsis in this
