A country of east-central Africa. By the late 18th century the region was the site of a Tutsi kingdom inhabited principally by Hutus. In 1890 it became part of German East Africa and later (1919) part of the Belgian League of Nations mandate of Ruanda-Urundi. Rwanda achieved independence from Belgium in 1962. In 1990 the country was invaded by the Rwandan Patriotic Front, a group largely composed of exiled Tutsis, which signed a peace agreement with the government in 1992. Ethnic fighting broke out again in 1994, however, with the Tutsis routing the Hutu government, causing over a million Hutus to flee to Zaire. Kigali is the capital and largest city. Population: 7,750,000.
