Serbia

Serbia, officially the Republic of Serbia, is a landlocked country in Southeast and Central Europe. Located in the Balkans, it borders Hungary to the north, Romania to the northeast, Bulgaria to the southeast, North Macedonia to the south, Croatia to the northwest, Bosnia and Herzegovina to the west, and Montenegro to the southwest. Serbia also claims to share a border with Albania through the disputed territory of Kosovo. Serbia has about 6.6 million inhabitants, excluding Kosovo. Serbia's capital, Belgrade, is also the largest city in the country.

Continuously inhabited since the Paleolithic age, the territory of modern-day Serbia faced Slavic migrations in the 6th century. Several regional states were founded in the Early Middle Ages and were at times recognised as tributaries to the Byzantine, Frankish and Hungarian kingdoms. The Serbian Kingdom obtained recognition by the Holy See and Constantinople in 1217, reaching its territorial apex in 1346 as the Serbian Empire. By the mid-16th century, the Ottoman Empire annexed the entirety of modern-day Serbia; their rule was at times interrupted by the Habsburg Empire, which began expanding towards Central Serbia from the end of the 17th century while maintaining a foothold in Vojvodina. In the early 19th century, the Serbian Revolution established the nation-state as the region's first constitutional monarchy, which subsequently expanded its territory. In 1918, in the aftermath of World War I, the Kingdom of Serbia united with the former Habsburg crownland of Vojvodina; later in the same year it joined with other South Slavic nations in the foundation of Yugoslavia, which existed in various political formations until the Yugoslav Wars of the 1990s. During the breakup of Yugoslavia, Serbia formed a union with Montenegro, which was peacefully dissolved in 2006, restoring Serbia's independence as a sovereign state. In 2008, representatives of the Assembly of Kosovo unilaterally declared independence, with mixed responses from the international community while Serbia continues to claim it as part of its own sovereign territory.

Serbia is an upper-middle income economy and provides universal health care and free primary and secondary education to its citizens. It is a unitary parliamentary constitutional republic, member of the UN, Council of Europe, OSCE, PfP, BSEC, CEFTA, and is acceding to the WTO. Since 2014, the country has been negotiating its EU accession, with the possibility of joining the European Union by 2030. Serbia formally adheres to the policy of military neutrality.

The origin of the name Serbia is unclear. Historically, authors have mentioned the Serbs (Serbian: Srbi / Срби) and the Sorbs of Eastern Germany (Upper Sorbian: Serbja; Lower Sorbian: Serby) in a variety of ways: Triballi, Cervetiis (Servetiis), gentis (S)urbiorum, Suurbi, Sorabi, Soraborum, Sorabos, Surpe, Sorabici, Sorabiet, Sarbin, Swrbjn, Servians, Sorbi, Sirbia, Sribia, Zirbia, Zribia, Suurbelant, Surbia, Serbulia / Sorbulia among others. These authors used these names to refer to Serbs and Sorbs in areas where their historical and current presence is not disputable (notably in the Balkans and Lusatia). However, there are also sources that have used similar names in other parts of the world (most notably in the Asiatic Sarmatia in the Caucasus).

There exist two prevailing theories about the origin of the ethnonym *Sŕbъ (plur. *Sŕby), one from a Proto-Slavic language with an appellative meaning of a "family kinship" and "alliance", while another from an Iranian-Sarmatian language with various meanings. In his work, De Administrando Imperio, Constantine VII Porphyrogenitus suggests that the Serbs originated from White Serbia near Francia.

From 1815 to 1882, the official name for Serbia was the Principality of Serbia. From 1882 to 1918, it was renamed to the Kingdom of Serbia, later from 1945 to 1963, the official name for Serbia was the People's Republic of Serbia. This was again renamed the Socialist Republic of Serbia from 1963 to 1990. Since 1990, the official name of the country has been the Republic of Serbia.

Archaeological evidence of Paleolithic settlements on the territory of present-day Serbia is scarce. A fragment of a hominid jaw found in Sićevo (Mala Balanica) is believed to be up to 525,000–397,000 years old.

Approximately 6,500 BC, during the Neolithic, the Starčevo and Vinča cultures existed in the region of modern-day Belgrade. They dominated much of Southeast Europe as well as parts of Central Europe and Anatolia. Several important archaeological sites from this era, including Lepenski Vir and Vinča-Belo Brdo, still exist near the Danube.
