Political instability: The Balkans have been plagued by political instability since the collapse of the Ottoman Empire in the early 20th century. This has been exacerbated by the rise of nationalism and the conflict between different ethnic groups.
Economic hardship: The Balkans have been struggling with economic hardship for many years. This has led to widespread poverty and unemployment, which has further fueled ethnic tensions.
External influence: The Balkans have been the scene of great power competition for centuries. This has sometimes led to foreign powers interfering in the region, which has only served to further destabilize the situation.
The combination of these factors led to the eruption of war in the Balkans in the early 1990s. The conflict lasted for several years and resulted in the deaths of hundreds of thousands of people.
