Yugoslavia's breakup in the 1990s marked a tumultuous period in European history. Economic challenges, rising nationalism, and the end of the Cold War destabilized the multi-ethnic federation, leading to a series of violent conflicts. The Yugoslav Wars saw widespread ethnic cleansing and atrocities, particularly in Bosnia. International intervention, including UN peacekeeping efforts and NATO airstrikes, eventually helped end the conflicts, but not before significant loss of life and displacement.
