This article examines war and peacetime ethnic relations at Vukovar General Hospital in Croatia's Eastern Slavonia region. A negotiated peace agreement paved the way for a multi-sectored approach to the reintegration of Eastern Slavonia back into the state and rapprochement between ethnic groups under the supervision of a United Nations transitional administration. This case study provides a glimpse into the realities of those peace-building processes on an institutional level in Eastern Slavonia's healthcare system. The reintegration of Vukovar hospital, the transition of Eastern Slavonia's health sector and peace-building in the region in general received much deserved accolades despite some flaws and minor setbacks. These experiences can still serve as a model for the rest of Croatia and for other countries emerging from civil conflicts.
