Slovenia, after declaring independence two days before is invaded by Yugoslav troops, tanks, and aircraft starting the Ten-Day War.

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

It was the second of the Yugoslav wars to start in 1991, following the Croatian War of Independence, and by far the shortest of the conflicts with fewest overall casualties.

Slovenia ( (listen) sloh-VEE-nee-ə; Slovene: Slovenija [slɔˈʋèːnija]), officially the Republic of Slovenia (Slovene: Republika Slovenija , abbr.: RS), is a country in Central Europe. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the southeast, and the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers 20,271 square kilometres (7,827 sq mi), and has a population of 2.1 million (2,108,708 people). Slovenes constitute over 80% of the country's population. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Continental climate is more pronounced towards the northeastern Pannonian Plain. The capital and largest city—Ljubljana—is nearly the centre of the country.Slovenia has historically been the crossroads of Slavic, Germanic, and Romance languages and cultures. Its territory has been part of many different states: the Roman Empire, the Byzantine Empire, the Carolingian Empire, the Holy Roman Empire, the Kingdom of Hungary, the Republic of Venice, the Illyrian Provinces of Napoleon's First French Empire, the Austrian Empire, and the Austro-Hungarian Empire. In October 1918, the Slovenes co-founded the State of Slovenes, Croats, and Serbs. In December 1918, they merged with the Kingdom of Serbia into the Kingdom of Yugoslavia. During World War II, Germany, Italy, and Hungary occupied and annexed Slovenia, with a tiny area transferred to Croatia, a Nazi puppet state at that time. In 1945, It became a founding member of Yugoslavia. Post-war, Yugoslavia was allied with the Eastern Bloc, but after the Tito-Stalin split of 1948, it never subscribed to the Warsaw Pact, and in 1961, it became one of the founders of the Non-Aligned Movement. In June 1991, Slovenia became the first republic to split from Yugoslavia and become an independent sovereign state.Slovenia is a developed country, with a high-income economy ranking highly in the Human Development Index. The Gini index rates its income inequality among the lowest the world. It is a member of the United Nations, the European Union, the Eurozone, the Schengen Area, the OSCE, the OECD, the Council of Europe, and NATO.
