When is a country not a country? Like states of Slovenia, Croatia, Bosnia and Macedonia, Kosovo region tried to broke away from Yugoslavia in the early 1990s and declared its independence. Unlike the others, it didn't stick and was only recognized by Albania. Part of the problem was that Kosovo is ethnically mostly Albanian, but historically it is very much part of the Serbian national identity - the Battle of Kosovo in 1389, despite being a defeat for the Serbs against the invading Ottoman Turks, is still a matter of great national pride and Serbs got their land back by fighting (with Greeks, Bulgarians etc.) to liberate Balkans from Ottoman rule. Also, it's worth mentioning that the Albanians became the majority in Kosovo only after Serbians in that region got killed or expelled by Ottomans and, later, by Albanian extremists during the World War 2 when Albania sided with the Axis forces and became an Italian protectorate, expanding to Kosovo. At any rate, a campaign during the 1990s of Albanian ultra-nationalist protests turned nasty after the Dayton Agreement (sorting out the war in the rest of Yugoslavia) didn't address Kosovo. Realising that the West just wasn't interested, the terrorist organization of "KLA" started a rather more ... active campaign. Slobodan Milosevic's Serbian army (well, technically Serbian/Montenegrin) responded, and the result was the NATO bombing of Serbia and Montenegro in 1999. Kosovo went into UN administration for the best part of a decade, with any attempt by the West to conclude independence being stymied by Russia in her traditional role as "Big Bro" to the Serbs. Eventually, in February 2008, Kosovo declared independence - however to date only a limited number of countries have recognized it. All of NATO has (except Spain, Romania, Greece and Slovakia, because all of them apart from Greecenote have independence movements back home: Basques in Spain, Hungarians in Slovakia, Székely/Hungarians in Romania), Russia has declared the independence to be "illegal" and China is passively supporting the Serbian side. Kosovo has wisely not applied for UN membership. On 22 July 2010, the International Court of Justice issued an advisory opinion after Serbia requested it that the declaration of independence was legal, which the International Court confirmed it was because there is no law that prohibits the declaration of independence. Lately, Kosovo got in international focus once more because the Republic of Crimea declared independence from pro-NATO Ukraine and became a part of the Russian Federation, which is now described as unlawful by the same countries who support the independence of Kosovo.

The Kosovar Flag
The blue field alludes to the United Nations, which administered the region after The Yugoslav Wars. At the center is a golden silhouette of the map of Kosovo — the only flag besides that of Cyprus to use its own map. The map in turn is crowned with six white stars, traditionally symbolizing the nation's six major ethnic groups: Albanians, Serbs, Turks, Gorani, Roma and Bosniaks; an Albanian ultra-nationalist ideology, meanwhile, attributes it to the regions of Greater Albania: mainland Albania, Kosovo, western parts of the Republic of Macedonia, parts of northern Greece, parts of southern Montenegro and the Presevo Valley in southern Serbia.
