Tutsi which the Hutu then in power killed an estimated 500,000–1,000,000 people, largely of Tutsi origin. Victorious in the aftermath of the genocide, the RPF came to power in July 1994. Tutsis speak Rwanda-Rundi as their native language. It is a member of the Bantu subgroup of the Niger–Congo family. Rwanda-Rundi is subdivided into the Kinyarwanda and Kirundi dialects, which have been standardized as official languages of Burundi and Rwanda. Rwanda-Rundi is also spoken as a mother tongue by the Hutu and Twa. Additionally, many Tutsis speak French, the third official language of Rwanda and Burundi, as a lingua franca. The
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.
