This article examines the roles of the Serbian Orthodox Church, the Catholic Church in Croatia, and the Islamic religious authority of Bosnia and Herzegovina in the 1991–1995 war inWestern Balkans. Religion in this case has been instrumental as a factor for galvanizing conflict and rationalizing its outcomes. The article also notes religious activities aimed at preventing violence and healing postconflict societies. The public influence of these religions began during the collapse of socialist Yugoslavia. Through the war and afterward, religions continued rebuilding resources and increasing influence. Traditional religion was blended with the new national ideologies carried out by ethnic nationalist parties allied with the ethnic majority churches established as state religions. Two decades after the Balkan war, the growing influence of these religions in public sphere coincides with the post-Yugoslav new ethnic nations’ failures in state building and democratic transition.
