During the nineties, Rwanda experienced several forms of internal violence, including civil war, genocide, reprisal killings and (counter-)insurgency. In addition, the armed con ‡ict triggered of an unprecedented refugee crisis in the Great Lakes region. In order to assess the relative impact of the di¤erent forms of violence and the refugee crisis, this article derives a detailed spatial pattern of wartime excess mortality from pre-and post-con ‡ict population census data. In line with previous evidence on the intensity of genocide, civil war and reprisal killings in Rwanda, we …nd signi…cant high-high excess mortality clusters in the southern province of Butare, in and around Kigali City, and in the eastern province Kibungo. Furthermore, we present the …rst quantitative evidence to date of high excess mortality in Gisenyi, the northwestern province which was the location of (counter-)insurgency and served as a corridor for more than a million refugees.A regression analysis indicates that both of these events contributed to a high death toll in Gisenyi.
