I examine the consequences of quota-based integration in Burundi’s military after a brutal and ethnically charged civil war. The evidence shows that at the macro level, the new Burundian military operates as a deeply integrated and cohesive institution. This is indicative of the possibility of quota-based integration in difﬁcult settings such as postwar Burundi. At the micro level, evidence from a natural experiment suggests that this cohesion may be undergirded by the fact that integration itself reduced prejudice and caused no apparent increase in ethnic salience among soldiers. This is indicative of the promise of quota-based integration as a strategy for addressing ethnic conﬂict in this difﬁcult setting.
