Yugoslav Wars: The Yugoslav People's Army begins the Ten-Day War in Slovenia.

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 entities known as republics that had previously constituted Yugoslavia: Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and Macedonia. SFR Yugoslavia's constituent republics declared independence due to rising nationalism. Unresolved tensions between ethnic minorities in the new countries led to the wars. While most of the conflicts ended through peace accords that involved full international recognition of new states, they resulted in a massive number of deaths as well as severe economic damage to the region.

The Yugoslav People's Army, also called the Yugoslav National Army, was the military of the Socialist Federal Republic of Yugoslavia and its antecedents from 1945 to 1992.

The Ten-Day War, or the Slovenian War of Independence, was a brief armed conflict that followed Slovenia's declaration of independence from Yugoslavia on 25 June 1991. It was fought between the Slovenian Territorial Defence together with the Slovene Police and the Yugoslav People's Army. It lasted from 27 June 1991 until 7 July 1991, when the Brioni Accords were signed.
