What is one reason that conflict broke out in the balkans in the 1990s?

One significant reason for the conflict in the Balkans during the 1990s was the rise of nationalism among various ethnic groups following the disintegration of Yugoslavia. As republics sought independence, tensions escalated between different ethnic communities, particularly between Serbs, Croats, and Bosniaks. The resulting power struggles and territorial disputes led to violent confrontations, including ethnic cleansing and war. This complex interplay of historical grievances, political aspirations, and ethnic identities fueled the devastating conflicts in the region.
