Yugoslav Wars: The city of Knin, Croatia, a significant Serb stronghold, is taken by Croatian forces during Operation Storm. The date is celebrated in Croatia as Victory Day.

The Yugoslav Wars were a series of separate but related ethnic conflicts, wars of independence, and insurgencies that took place from 1991 to 2001 in what had been the Socialist Federal Republic of Yugoslavia. The conflicts both led up to and resulted from the breakup of Yugoslavia, which began in mid-1991, into six independent countries matching the six republics that had previously constituted Yugoslavia: Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and Macedonia, which was later renamed to North Macedonia. The breakup of Yugoslavia and the accompanying Yugoslav Wars are commonly attributed to increasing nationalism and unresolved ethnic tensions in Yugoslavia. While most of the conflicts ended through peace accords that involved full international recognition of the new states, they resulted in the deaths of many as well as severe economic damage to the region.
