Hutu and 14% of residents in Rwanda and Burundi, respectively. The Twa pygmies, the smallest of the two countries' principal populations, also share language and culture with the Hutu and Tutsi. However, they are distinguished by a considerably shorter stature. The Hutu are believed to have first emigrated to the Great Lake region from West Africa in the great Bantu expansion. Various theories have emerged to explain the purported physical differences between them and their fellow Bantu-speaking neighbors, the Tutsi. One such thesis, largely based on oral tradition, posits that the Tutsi experienced some admixture with or were partially descended from
Sainte-Famille Church genocide of 1994 thousands of Tutsi and Hutu took refuge in the church and many were massacred, following the death of President Juvénal Habyarimana. Witnesses said that the priest in charge of the church, Father Wenceslas Munyeshyaka, armed himself and helped Hutu militias take people from the church to be killed. Munyeshyaka was responsible for many of the killings, agreeing to "let the militia pick off those they wanted every now and then." Wenceslas Munyeshyaka hated the Tutsis and called them the "inyenzis". Following this incident and similar ones in other churches, many of the Rwandan people converted to Islam.
