For centuries, the two tribes that make up the country of Rwanda, the Hutus and the Tutsis, have been warring against each other. The tribe in power has shifted back and forth between the two, often after many brutal deaths in the upheaval for control. The tension between the parties came to a head in 1994 when exiled Tutsi rebels invaded the capital. In retaliation, the Hutu government called for the extinction of the Tutsi people. Hutus across the country took up guns and machetes and went to work. When the mass murder was finally over after one hundred days, about one million people had been killed, more than 90% of them Tutsis. That works about to be 10,000 people a day. Most Americans never knew what happened.
