Bosnia and Herzegovina declares its independence from Socialist Federal Republic of Yugoslavia.

The Socialist Federal Republic of Yugoslavia, commonly referred to as SFR Yugoslavia or simply Yugoslavia, was a socialist country in Central and Southeast Europe that existed from its foundation in the aftermath of World War II until its dissolution in 1992 amid the Yugoslav Wars. Covering an area of 255,804 km2 (98,766 sq mi), the SFRY bordered the Adriatic Sea and Italy to the west, Austria and Hungary to the north, Bulgaria and Romania to the east, and Albania and Greece to the south. It was a one-party socialist state and federation governed by the League of Communists of Yugoslavia and made up of six socialist republicsBosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Sloveniawith Belgrade as its capital; it also included two autonomous provinces within Serbia: Kosovo and Vojvodina.

The SFRY traces its origins to 26 November 1942, when the Anti-Fascist Council for the National Liberation of Yugoslavia was formed during World War II to resist Axis occupation of the Kingdom of Yugoslavia. Following the country's liberation, King Peter II was deposed, the monarchy was ended, and on 29 November 1945 the Federal People's Republic of Yugoslavia was proclaimed. Led by Josip Broz Tito, the new communist government sided with the Eastern Bloc at the beginning of the Cold War but pursued a policy of neutrality following the TitoStalin split in 1948; it became one of the founding members of the Non-Aligned Movement, and transitioned from a command economy to market-based socialism.

Following the death of Tito on 4 May 1980, the Yugoslav economy started to collapse, which increased unemployment and inflation. The economic crisis led to rising ethnic nationalism and political dissidence in the late 1980s and early 1990s. With the fall of communism in Eastern Europe, efforts to transition into a confederation also failed; the two wealthiest republics, Croatia and Slovenia, seceded and gained some international recognition in 1991. The federation dissolved along the borders of federated republics, hastened by the start of the Yugoslav Wars, and the federation formally broke up on 27 April 1992. Two republics, Serbia and Montenegro, remained within a reconstituted state known as the Federal Republic of Yugoslavia, or FR Yugoslavia, but this state was not recognized internationally as the official successor state to SFR Yugoslavia. Former Yugoslavia is now commonly used retrospectively.

Bosnia and Herzegovina (Bosna i Hercegovina / Босна и Херцеговина, pronounced [bôsna i xěrtseɡoʋina]), abbreviated BiH or B&H, sometimes called Bosnia–Herzegovina and often known informally as Bosnia, is a country at the crossroads of south and southeast Europe, located in the Balkans. The capital and largest city is Sarajevo. Bosnia and Herzegovina borders Serbia to the east, Montenegro to the southeast, and Croatia to the north and southwest. It is not entirely landlocked; in the south it has a narrow coast on the Adriatic Sea within the Mediterranean, which is about 20 kilometres (12 miles) long and surrounds the town of Neum. Bosnia, which is the inland region of the country, has a moderate continental climate with hot summers and cold, snowy winters. In the central and eastern regions of the country, the geography is mountainous, in the northwest it is moderately hilly, and in the northeast it is predominantly flat. Herzegovina, which is the smaller, southern region of the country, has a Mediterranean climate and is mostly mountainous.

The area that is now Bosnia and Herzegovina has been inhabited by human beings since at least the Upper Paleolithic, but evidence suggests that during the Neolithic age, permanent human settlements were established, including those that belonged to the Butmir, Kakanj, and Vučedol cultures. After the arrival of the first Indo-Europeans, the area was populated by several Illyrian and Celtic civilizations. Culturally, politically, and socially, the country has a rich and complex history. The ancestors of the South Slavic peoples that populate the area today arrived during the 6th through the 9th century. In the 12th century, the Banate of Bosnia was established; by the 14th century, this had evolved into the Kingdom of Bosnia. In the mid-15th century, it was annexed into the Ottoman Empire, under whose rule it remained until the late 19th century. The Ottomans brought Islam to the region, and altered much of the country's cultural and social outlook.

From the late 19th century until World War I, the country was annexed into the Austro-Hungarian monarchy. In the interwar period, Bosnia and Herzegovina was part of the Kingdom of Yugoslavia. After World War II, it was granted full republic status in the newly formed Socialist Federal Republic of Yugoslavia. In 1992, following the breakup of Yugoslavia, the republic proclaimed independence. This was followed by the Bosnian War, which lasted until late 1995 and was brought to a close with the signing of the Dayton Agreement.

Today, the country is home to three main ethnic groups, designated “constituent peoples” in the country's constitution. The Bosniaks are the largest group of the three, the Serbs are the second-largest, and the Croats are the third-largest. In English, all natives of Bosnia and Herzegovina, regardless of ethnicity, are called Bosnian. Minorities, who under the constitution are categorized as "others", include Jews, Roma, Albanians, Montenegrins, Ukrainians and Turks.

Bosnia and Herzegovina has a bicameral legislature and a three-member presidency made up of one member from each of the three major ethnic groups. However, the central government's power is highly limited, as the country is largely decentralized. It comprises two autonomous entities—the Federation of Bosnia and Herzegovina and Republika Srpska—and a third unit, the Brčko District, which is governed by its own local government. The Federation of Bosnia and Herzegovina furthermore consists of 10 cantons.

Bosnia and Herzegovina is a developing country and ranks 73rd in human development. Its economy is dominated by industry and agriculture, followed by tourism and the service sector. Tourism has increased significantly in recent years. The country has a social-security and universal-healthcare system, and primary- and secondary-level education is tuition-free. It is a member of the UN, the Organization for Security and Co-operation in Europe, the Council of Europe, the Partnership for Peace, and the Central European Free Trade Agreement; it is also a founding member of the Union for the Mediterranean, established in July 2008. The country is an applicant for membership in the European Union and has been a candidate for NATO membership since April 2010, when it received a Membership Action Plan.
