Tensions between Tutsi and Hutu had been escalating during the 1950s, and culminated in the 1959 Rwandan Revolution. Hutu activists began killing Tutsi, forcing more than 100,000 Tutsis to seek refuge in neighbouring countries. Kagame's family abandoned their home and lived for two years in the far northeast of Rwanda and eventually crossing the border into Uganda. They moved gradually north, and settled in the Nshungerezi refugee camp in the Toro sub-region in 1962. It was around this time that Kagame first met Fred Rwigyema, the future leader of the Rwandan Patriotic Front.
