Overview

The Croats are believed to be a purely Slavic people who migrated from Ukraine and settled in present-day Croatia during the 6th century. After a period of self-rule, Croatians agreed to the Pacta Conventa in 1091, submitting themselves to Hungarian authority. By the mid-1400s, concerns over Ottoman expansion led the Croatian Assembly to invite the Habsburgs, under Archduke Ferdinand, to assume control over Croatia. Habsburg rule proved successful in thwarting the Ottomans, and by the 18th century, much of Croatia was free of Turkish control.

In 1868, Croatia gained domestic autonomy while remaining under Hungarian authority. Following World War I and the demise of the Austro-Hungarian Empire, Croatia joined the Kingdom of Serbs, Croats, and Slovenes (the Kingdom of Serbs, Croats, and Slovenes became Yugoslavia in 1929). Yugoslavia changed its name once again after World War II. The new state became the Federal Socialist Republic of Yugoslavia and united Croatia and several other states together under the communistic leadership of Marshall Tito (born Josip Broz).

After the death of Tito and with the fall of communism throughout eastern Europe, the Yugoslav federation began to crumple. Croatia held its first multi-party elections since World War II in 1990. Long-time Croatian nationalist Franjo Tudjman was elected President, and one year later, Croatians declared independence from Yugoslavia. Conflict between Serbs and Croats in Croatia escalated, and one month after Croatia declared independence, civil war erupted.

The United Nations mediated a cease-fire in January 1992, but hostilities resumed the next year when Croatia fought to regain one-third of the territory lost the previous year. A second cease-fire was enacted in May 1993, followed by a joint declaration the next January between Croatia and Yugoslavia. However, in September 1993, the Croatian Army led an offensive against the Serb-held Republic of Krajina. A third cease-fire was called in March 1994, but it, too, was broken in May and August 1995 after Croatian forces regained large portions of Krajina, prompting an exodus of Serbs from this area. In November 1995, Croatia agreed to peacefully reintegrate Eastern Slavonia, Baranja, and Western Dirmium under terms of the Erdut Agreement. In December 1995, Croatia signed the Dayton peace agreement, committing itself to a permanent cease-fire and the return of all refugees.

The death of President Tudjman in December 1999, followed by the election of a coalition government and President in early 2000, brought significant changes to Croatia. The government, under the leadership of Prime Minister Racan, progressed in implementation of the Dayton Peace Accords, regional cooperation, refugee returns, national reconciliation, and democratization.

On November 23, 2003, national elections were held for Parliament. The new government, headed by Prime Minister Ivo Sanader, took office in December 2003. The Sanader government has continued to build upon the changes first set forth under the Racan government. Presidential elections were held in January 2005.  President Mesic was re-elected to a second term in office, defeating HDZ candidate Jadranka Kosor in two rounds of balloting. The inauguration of President Mesic was February 18, 2005.

Historical Eras

The major periods of {country}’s history at a glance.

  1. Early Slavic Settlement

    600 – 925

    Slavic tribes, believed to have migrated from present-day Ukraine, settled the Dalmatian coast and Pannonian plains during the 7th century. The region gradually coalesced into distinct Croatian principalities, navigating pressures from Byzantium, the Franks, and neighboring peoples. Duke Branimir achieved de facto international recognition from Pope John VIII in 879, marking a formative step toward Croatian statehood.

  2. Medieval Croatian Kingdom

    925 – 1102

    Tomislav united Croatian lands and was recognized as the first king of Croatia around 925, establishing one of medieval Europe's notable early monarchies. The kingdom reached its territorial and cultural peak under kings such as Petar Krešimir IV in the 11th century. The Pacta Conventa of 1102 brought Croatia into a personal union with Hungary, ending fully independent Croatian rule while preserving certain noble privileges.

  3. Habsburg & Ottoman Era

    1102 – 1918

    Following the Hungarian union, Croatia faced existential pressure from Ottoman expansion, prompting the Croatian Assembly to invite the Habsburgs under Archduke Ferdinand to assume sovereignty in 1527. For two centuries Croatia served as the Antemurale Christianitatis — the bulwark of Christendom — suffering devastating raids and territorial losses before the 1699 Treaty of Karlowitz largely freed the region from Ottoman control. The 1868 Croatian-Hungarian Settlement granted Croatia domestic autonomy, and a national revival movement fostered a distinct Croatian cultural and political identity within the empire.

  4. Yugoslavia Period

    1918 – 1991

    After the collapse of Austria-Hungary in 1918, Croatia joined the Kingdom of Serbs, Croats, and Slovenes, renamed Yugoslavia in 1929. World War II brought a brutal Nazi-installed Ustasha puppet state and fierce partisan resistance led by Josip Broz Tito, who subsequently ruled a unified communist Federal Socialist Republic of Yugoslavia until his death in 1980. Economic stagnation and rising nationalism in the 1980s eroded the federation's cohesion, culminating in Croatia's first free multi-party elections in 1990.

  5. Independence & Homeland War

    1991 – 1998

    Croatia declared independence in June 1991 under President Franjo Tuđman, triggering a brutal war as Yugoslav federal forces and Serb paramilitaries seized roughly one-third of Croatian territory, including the self-proclaimed Republic of Krajina. A series of UN-brokered ceasefires repeatedly broke down before Croatia's Operation Storm in August 1995 recaptured the Krajina and the Erdut Agreement provided for the peaceful reintegration of Eastern Slavonia. Full territorial integrity was restored in 1998 when the last UN-administered Serb-held enclave was returned.

  6. Democratic & European Integration

    1998 – present

    Following Tuđman's death in 1999, a reformist coalition government under Prime Minister Ivica Račan accelerated democratization, refugee returns, and cooperation with the International Criminal Tribunal. Croatia joined NATO in 2009 and became the 28th member state of the European Union on 1 July 2013, completing its post-war transformation into a consolidated democracy and market economy. The country adopted the euro and entered the Schengen Area in January 2023, cementing its full integration into the European mainstream.
