The majority Hutu population rebelled against the feudal Tutsi rule in 1959-62, leading to the massacre of thousands of Tutsis. Large numbers fled to Uganda. The first President of the republic was deposed in 1973 and was replaced by a military government under general Habyasima, who established a one-party state.

Armed Tutsi exiles repeatedly attempted to invade Rwanda in the 1960s and 70s but were always defeated by the Hutu army. Continued Hutu-Tutsi conflict left thousands dead over a period of 30 years.

In October 1990, Rwanda was invaded by the Rwandan Patriotic Front (RPF) of exiled Tutsis and some moderate Hutus, who were against the one party system. The invaders forced the one-party Government to introduce a multi-party Constitution in 1991. When the Government refused to honour the 1992 Peace Agreement, the RPF advanced on Kigali and forced the Government to begin negotiations again. This resulted in a peace accord in August 1993, known as the Arusha accord. This accord provided for a transitional period under a broad-based government including the RPF until the 1995 elections and a presence of United Nations forces in the country during this period.

President Habyarima who had retained the presidency during this period, died on 6 April 1994 in a plane crash, probably caused by a rocket attack by extremists of the Hutu army. This army and militia then carried out a pre-planned act of genocide against the Tutsi minority and moderate Hutus. 500,000 preople were massacred in three months. The civil war began again and the RPF gradually re-established control over the country and forced the defeated government troops and 2 million Hutu refugees out of the country. Finally, on 18 July 1994, the RPF declared victory and established a government of National Unity.

Between 50,000 and 60,000 Hutu refugees died of disease in refugee camps in eastern Zaire (now the Democratic Republic of Congo) in the summer of 1994. French troops with drew from their ‘safe zone’ in the south-west of the country in September 1994 and were replaced by RPF forces that gradually returned most of the refugees in the zone to their homes. UN forces (UNAMIR II), which included British troops, were also deployed to deter revenge attacks by either side.
After November 1994, there was a gradual return of the refugees to Rwanda. It is estimated that 200,000 returnd from Uganda, but by December 1995, 500,000 refugees remained in Tanzania and over a million in Zaire. UN forces left the country in March 1996 and the killings by both sides continued and Hutu attacks in central and western Rwanda were frequent in the first half of 1998.

Rwanda has supported a rebellion in the Democratic Republic of Congo (qv) led by the Congolese Democratic Rally, a Congolese Tutsi Group. Rwandese troops have also been deployed in the Congo.

Local elections took place on 29-31 March 1999, the first for nine years and the transitional National Assembly was extended for four further years in June 1999.
