Ethnic groups in Rwanda

The largest ethnic groups in Rwanda are the Hutus, which make up about 85% of Rwanda's population; the Tutsis, which are 14%; and the Twa, which are around 1%. Starting with the Tutsi feudal monarchy rule of the 10th century, the Hutus were a subjugated social group. Belgian colonization also contributed to the tensions between the Hutus and Tutsis. Hutu Power ideology propagated the myth that Hutus were the superior ethnicity. The resulting tensions would eventually foster the slaughtering of Tutsis in the Rwandan genocide. Since then, policy has changed to recognize one main ethnicity: "Rwandan".

In comparison to the Hutu (4.3% B), the Tutsi have three times as much halogroup B (14.9% B), a haplogroup found at the highest rate in different African pygmies populations.
