The 코소보 전쟁 occurred from 1998 to 1999 in the 코소보 region of 유고슬라비아. It was primarily a conflict between the 유고슬라비아 정부 and the 코소보 해방군, which sought independence for the ethnic 알바니아인 population. The war resulted in significant civilian casualties and widespread displacement. In March 1999, the NATO alliance intervened with airstrikes against 유고슬라비아 to stop the humanitarian crisis. The conflict ended in June 1999, leading to the establishment of a UN administration in 코소보. In 2008, 코소보 declared independence, which remains a contentious issue in international relations.
