The Rwandan genocide was caused by a power struggle between the two dominant tribes in both Rwanda and Burundi. The Hutu and the Tutsi. They had been massacring each other in those two countries for a long time after independance and a civil war between the two groups had been going on in the early 1990 but In 1994, the Hutu Rwandan president was killed when his plane exploded mid-flight. Angry Hutus where angry and decieded to attack the Tutsi’s.Over a period of 3 months(100 days), over 800,000 Tutsis and some of their Hutu allies were killed. Millions of Tutsis left to the Congo, Uganda or Burundi. A Tutsi rebel group, the RPF began an offensive to win back Rwand.
