Rwanda, just south of the Equator in central Africa, is a mountainous land. This tiny, landlocked country—the continent's most densely populated—gained independence from Belgium in 1962. Conflict and civil war between ethnic Hutus and Tutsis have marked the country's history. In 1994 the genocide of some 800,000 Tutsis by Hutus occurred before Tutsi forces could gain control of Rwanda. Hutu militias fled Rwanda and continued to attack Tutsis from Zaire until Rwandan forces invaded Zaire in 1997—where they remained until 2002, when the Democratic Republic of the Congo (formerly Zaire) agreed to help disarm Hutu gunmen.
