Kosovo: The Contested Country

A small Balkan territory that is a heartland of Serbian Orthodoxy and has an overwhelming Albanian majority — five centuries under the Ottomans, a decade of repression, a war, NATO's intervention, and a disputed independence

A place two nations claim

Kosovo is a landlocked territory in the central Balkans, about the size of a small county, with nearly 1.6 million people. More than nine in ten are ethnic Albanians; a Serb minority, 2.3 per cent in the 2024 census, is concentrated in the north and in scattered enclaves. It is also the site of the most sacred places of Serbian Orthodoxy and of the battle at the centre of Serbian national myth. Since 2008 it has been an independent state, recognised by around 110 UN member states — but not by Serbia, Russia or China, and it is not a member of the United Nations.

Medieval Serbia, and the battle

Ancient Dardania, then Roman and Byzantine, Kosovo became in the Middle Ages the core of the Serbian state — the seat of the Serbian Orthodox Patriarchate at Peć, and the site of great monasteries like Gračanica and Visoki Dečani. On 15 June 1389 (28 June in today's calendar) a Serbian-led coalition met the Ottomans at the Field of Blackbirds; both the Serbian prince Lazar and Sultan Murad were killed, and the battle entered Serbian epic as the heroic defeat that sealed the medieval kingdom's fall.

Two histories of one land

Under five centuries of Ottoman rule the population shifted: Albanian Muslims moved in and converted, while many Serbs migrated north — notably in the Great Migrations during the Habsburg–Ottoman wars of 1683–99 and 1737–39. By the Balkan Wars of 1912 Kosovo was majority Albanian.

Serbia, Yugoslavia, and the loss of autonomy

Serbia and Montenegro took Kosovo from the Ottomans in 1912, and in 1918 it became part of the new Kingdom of Serbs, Croats and Slovenes, later Yugoslavia, through decades in which Albanians were largely shut out of public life. Socialist Yugoslavia's 1974 constitution then made Kosovo an autonomous province with nearly the powers of a republic — its own assembly, courts and Albanian-language university.

Slobodan Milošević rose to power in Serbia partly by championing Kosovo's Serbs, and in 1989 his government drastically reduced Kosovo's autonomy and began the cultural oppression of its Albanian population. Kosovo Albanians responded with a decade of non-violent parallel institutions under Ibrahim Rugova — until the 1995 Dayton Agreement ignored Kosovo, and the armed Kosovo Liberation Army took the field.

The war and NATO

Serbian forces waged a harsh counterinsurgency against the KLA and Albanian civilians. After talks failed, NATO began a 78-day bombing campaign against Yugoslavia in March 1999 — carried out without UN Security Council authorisation, and legally contested ever since.

During the NATO campaign, Serbian forces expelled some 848,000 Albanians from Kosovo; over the two-year conflict more than 13,500 people were killed or went missing. Serbian forces withdrew in June 1999, after which around 200,000 Serbs, Roma and other non-Albanians fled Kosovo, amid reports of abuse. (UK Ministry of Defence / Wikimedia Commons)

UN Security Council Resolution 1244 then placed Kosovo under UN administration with a NATO-led peacekeeping force, formally still part of Serbia but self-governing.

Independence, and the dispute

After UN-mediated status talks failed — Russia blocked a plan for supervised independence — Kosovo's assembly declared independence on 17 February 2008. The International Court of Justice ruled in 2010 that the declaration did not violate international law.

An EU-facilitated dialogue between Belgrade and Pristina has run since 2011, but the Serb-majority north around Mitrovica remains a flashpoint, with barricades and, in 2023, an armed clash. Kosovo is among Europe's poorest countries, sustained by a large diaspora, and a special court in The Hague has tried former KLA leaders for war crimes; in September 2026 it convicted the former president Hashim Thaçi and sentenced him to 25 years in prison.

What Kosovo carries

Kosovo is a territory where two national histories overlap and neither will yield: the Serbian one, medieval, Orthodox, rooted in monasteries and the battle of 1389; and the Albanian one, an overwhelming present-day majority with its own founding moment at Prizren in 1878. The 1990s turned that overlap into repression, war and mass expulsion. Independence resolved the question for most Kosovo Albanians and for much of the West, and left it open for Serbia, Russia and a divided international community.
