The Rwandan genocide happened in 1994. It started in April and lasted 100 days. During that time, about 800,000 people were murdered.
In a genocide, many or all people in a group are killed because of their ethnicity, colour, religion, or political opinions. In the Rwandan genocide, members of an ethnic group called the Tutsi (abatutsi) were killed because of their ethnicity. The killers were extremist members of another ethnic group called the Hutu (abahutu). The Hutu killers also killed other Hutus whose political beliefs were not as extreme as theirs.
