Between 1920 and 1994, the Catholic Church was Rwanda's most dominant social and religious institution. In recent years, the church has been critiqued for its perceived complicity in the ethnic discourse and political corruption that culminated with the 1994 genocide. In analyzing the contested legacy of Catholicism in Rwanda, Rwanda Before the Genocide focuses on a critical decade, from 1952 to 1962, when Hutu and Tutsi identities became politicized, essentialized, and associated with political violence. This study--the first English-language church history on Rwanda in over 30 years--examines the reactions of Catholic leaders such as the Swiss White Father André Perraudin and Aloys Bigirumwami, Rwanda's first indigenous bishop. It evaluates Catholic leaders' controversial responses to ethnic violence during the revolutionary changes of 1959-62 and after Rwanda's ethnic massacres in 1963-64, 1973, and the early 1990s. In seeking to provide deeper insight into the many-threaded roots of the Rwandan genocide, Rwanda Before the Genocide offers constructive lessons for Christian ecclesiology and social ethics in Africa and beyond.
