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.

The Kingdom of Serbia was a country located in the Balkans which was created when the ruler of the Principality of Serbia, Milan I, was proclaimed king in 1882. Since 1817, the Principality was ruled by the Obrenović dynasty (replaced by the Karađorđević dynasty for a short time). The Principality of Serbia, under the suzerainty of the Turkish Empire, de facto achieved full independence when the very last Ottoman troops left Belgrade in 1867. The Congress of Berlin in 1878 recognized the formal independence of the Principality of Serbia, and in its composition Nišava, Pirot, Toplica and Vranje districts entered the South part of Serbia.

In 1882, Serbia was elevated to the status of a kingdom, initially maintaining a foreign policy friendly to Austria-Hungary before turning to the Russian Empire and France following a coup d'état in 1903. Between 1912 and 1913, Serbia greatly enlarged its territory through engagement in the First and Second Balkan Wars – Sandžak-Raška, Kosovo Vilayet and Vardar Macedonia were annexed. At the end of World War I in 1918 it united with Vojvodina and the Kingdom of Montenegro, and in December 1918 it merged with the newly created State of Slovenes, Croats and Serbs to form the Kingdom of Serbs, Croats and Slovenes (later known as Kingdom of Yugoslavia) under the continued rule of the Karađorđević dynasty.

The Danube (/ˈdæn.juːb/ DAN-yoob; see also other names) is a river in Europe, the second-longest after the Volga in Russia. It flows through Central and Southeastern Europe, from the Black Forest of Germany south through the Danube Delta in Romania into the Black Sea. A large and historically important river, it was once a frontier of the Roman Empire. In the 21st century, it connects ten European countries, running through their territories or marking a border. Originating in Germany, the Danube flows southeast for 2,850 km (1,770 mi), passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine. Among the many cities on the river are four national capitals: Vienna, Bratislava, Budapest, and Belgrade. Its drainage basin amounts to 817,000 km (315,000 sq mi) and extends into nine more countries.

The Danube's longest headstream, the Breg, rises in Furtwangen im Schwarzwald, while the river carries its name from its source confluence in the palace park in Donaueschingen onwards. Since ancient times, the Danube has been a traditional trade route in Europe. Today, 2,415 km (1,501 mi) of its total length are navigable. The Danube is linked to the North Sea via the Rhine–Main–Danube Canal, connecting the Danube at Kelheim with the Main at Bamberg. The river is also an important source of hydropower and drinking water.

The art of Europe, also known as Western art, encompasses the history of visual art in Europe. European prehistoric art started as mobile Upper Paleolithic rock and cave painting and petroglyph art and was characteristic of the period between the Paleolithic and the Iron Age. Written histories of European art often begin with the Aegean civilizations, dating from the 3rd millennium BC. However a consistent pattern of artistic development within Europe becomes clear only with Ancient Greek art, which was adopted and transformed by Rome and carried; with the Roman Empire, across much of Europe, North Africa and Western Asia.

The influence of the art of the Classical period waxed and waned throughout the next two thousand years, seeming to slip into a distant memory in parts of the Medieval period, to re-emerge in the Renaissance, suffer a period of what some early art historians viewed as "decay" during the Baroque period, to reappear in a refined form in Neo-Classicism and to be reborn in Post-Modernism.

Divine Liturgy (Koine Greek: Θεία Λειτουργία, romanized: Theía Leitourgía, pronounced [ˈθi.a li.turˈʝi.a]) or Holy Liturgy is the usual name used in most Eastern Christian rites for the Eucharistic service.

The Eastern Orthodox Churches, Eastern Catholic Churches and Eastern Lutheran Churches believe the Divine Liturgy transcends both time and the world. All believers are seen as united in worship in the Kingdom of God along with the departed saints and the angels of heaven. Everything in the liturgy is seen as symbolic, but not merely so, for it makes present the unseen reality. According to Eastern tradition and belief, the liturgy's roots go back to the adaptation of Jewish liturgy by Early Christians. The first part, termed the "Liturgy of the Catechumens", includes the reading of scriptures like those in a synagogue, and in some places, also a sermon/homily. The second half, the "Liturgy of the Faithful", is based on the Last Supper and the first Eucharistic celebrations by Early Christians. Eastern Christians (and many other branches of Christianity) believe that the Eucharist is the central part of the service in which they participate, as they believe the bread and wine truly become the real Body and Blood of Christ, and that by partaking of it they jointly become the Body of Christ (that is, the Church). Each liturgy has its differences from others, but most are very similar to each other with adaptations based on tradition, purpose, culture and theology.

Christianity is the predominant religion in Serbia. The Constitution of Serbia defines it as a secular state with guaranteed religious freedom. Eastern Orthodox Christians with 6,079,396 members, comprise 84.5% of country's population. The Serbian Orthodox Church is the largest and traditional church of the country; adherents of it are overwhelmingly Serbs. Public schools in Serbia allow religious teaching, most commonly with the Serbian Orthodox Church. Serbian public holidays include the religious celebrations of Eastern Orthodox Christians. Other Orthodox Christian communities in Serbia include Montenegrins, Romanians, Macedonians, and Bulgarians. The Catholic Church is prominent in north Vojvodina amongst the Hungarian minority. Protestantism is most largely found in Slovak populations within Bački Petrovac and Kovačica. Christianity first arrived in Serbia in the 9th century. It became state-religion in the 9th century when Serbia began to identify as a Christian country. In a 2011 census, 91.22% of Serbians identified as Christian.

Dragutin Inkiostri-Medenjak (Serbian Cyrillic: Драгутин Инкиостри Медењак; 1866–1942) was a Serbian painter, collector of folk ornaments and handicrafts, and is considered the first interior designer in Serbia. In 1912, he was put in charge of designing the interior of the House of Vuk's Foundation.

He was born in Split as Carlo Inchiostri. After settling down in Belgrade, he changed his name to Dragutin and added his mother's surname. Following studies in Florence, he travelled through Serbia and the rest of Yugoslavia. Inkiostri Medenjak wrote his chief work Moja teorija o dekorativnoj srpskoj umetnosti i njenoj primeni in 1925.

Ferizaj or Uroševac, is a city and a municipality in Kosovo. It is the third largest city in Kosovo by population and also the seat of Ferizaj Municipality and the Ferizaj District. According to the last census of 2024, the municipality of Ferizaj has 109,255 inhabitants.

Ferizaj has been populated since the prehistoric era by the Starčevo, Vinča and Baden culture. During the Ottoman period, Ferizaj served as a trading centre on the route between Belgrade and Thessaloniki. Ferizaj has always been considered as a city where tolerance and coexistence in terms of religion and culture has been part of the society in the last centuries. During and after the Kosovo War in 1999, the US Army base Camp Bondsteel was established outside of the city, now being used by forces belonging to KFOR. It is the largest and the most expensive foreign military base built by the Americans in South Eastern Europe, since the Vietnam War.

Vojvodina (Serbian: Војводина, IPA: [vǒjvodina], VOY-və-DEE-nə), officially the Autonomous Province of Vojvodina (Serbian: Аутономна Покрајина Војводина, romanized: Autonomna Pokrajina Vojvodina), is an autonomous province in northern Serbia. It encompasses the historical and geographical regions of Bačka, Banat, Syrmia, and northernmost part of Mačva, lying to the north of the national capital Belgrade and the Sava and Danube rivers. Vojvodina has 1.7 million inhabitants, about a quarter of the country's population, and its administrative centre, Novi Sad, is the second largest city in Serbia.

The Socialist Federal Republic of Yugoslavia (commonly abbreviated as SFRY or SFR Yugoslavia), known from 1945 to 1963 as the Federal People's Republic of Yugoslavia, commonly referred to as Socialist Yugoslavia or simply Yugoslavia, was a country in Central and Southeast Europe. It was established in 1945, following World War II, and lasted until 1992, dissolving amid the onset of the Yugoslav Wars. Spanning an area of 255,804 square kilometres (98,766 sq mi) in the Balkans, Yugoslavia was bordered by 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 had six constituent republics: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Within Serbia was the Yugoslav capital city of Belgrade as well as two autonomous Yugoslav provinces: Kosovo and Vojvodina.

The country emerged as Democratic Federal Yugoslavia on 29 November 1943, during the second session of the Anti-Fascist Council for the National Liberation of Yugoslavia midst World War II in Yugoslavia. Recognised by the Allies of World War II at the Tehran Conference as the legal successor state to Kingdom of Yugoslavia, it was a provisionally governed state formed to unite the Yugoslav resistance movement. Following the country's liberation, King Peter II was deposed, the monarchical rule 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 1948 Tito–Stalin split; it became a founding member of the Non-Aligned Movement, and transitioned from a command economy to market-based socialism. The country was renamed Socialist Federal Republic of Yugoslavia in 1963.

The May Coup (Serbian: Мајски преврат, romanized: Majski prevrat) was a coup d'état in the Kingdom of Serbia which resulted in the assassination of King Alexander I and his consort, Queen Draga, inside the Stari Dvor in Belgrade on the night of 10–11 June [O.S. 28–29 May] 1903. This act resulted in the extinction of the Obrenović dynasty that had ruled Serbia since the middle of the 19th century. A group of army officers led by Captain Dragutin Dimitrijević (Apis) organized the assassination. After the May Coup, the throne passed to King Peter I of the Karađorđević dynasty.

Along with the royal couple, the conspirators killed prime minister Dimitrije Cincar-Marković, minister of the army Milovan Pavlović [sr], and general-adjutant Lazar Petrović. The coup had a significant influence on Serbia's relations with other European powers; the Obrenović dynasty had mostly allied with Austria-Hungary, while the Karađorđević dynasty had close ties both with Russia and with France. Each dynasty received ongoing financial support from their powerful foreign sponsors.

Cluj-Napoca (/ˈkluːʒnæˌpoʊkə/ KLOOZH-na-POH-kə; Romanian: [ˈkluʒ naˈpoka] ), or simply Cluj (Hungarian: Kolozsvár [ˈkoloʒvaːr] , German: Klausenburg), is a city in northwestern Romania. It is the second-most populous city in the country and the seat of Cluj County. Geographically, it is roughly equidistant from Bucharest (445 km; 277 mi), Budapest (461 km; 286 mi) and Belgrade (483 km; 300 mi). Located in the Someșul Mic river valley, the city is considered the unofficial capital of the historical province of Transylvania. For some decades prior to the Austro-Hungarian Compromise of 1867, it was the official capital of the Grand Principality of Transylvania.

As of 2021, 286,598 inhabitants live in the city. The Cluj-Napoca metropolitan area had a population of 411,379 people, while the population of the peri-urban area is approximately 420,000. According to a 2007 estimate, the city hosted an average population of over 20,000 students and other non-residents each year from 2004 to 2007. The city spreads out from St. Michael's Church in Unirii Square, built in the 14th century and named after the Archangel Michael, Cluj's patron saint. The municipality covers an area of 179.52 square kilometres (69.31 sq mi).

Banat (UK: /ˈbænɪt, ˈbɑːn-/ BAN-it, BAHN-, US: /bəˈnɑːt, bɑː-/ bə-NAHT, bah-; Romanian: Banat; Hungarian: Bánság; Serbian: Банат, romanized: Banat) is a geographical and historical region located in the Pannonian or Carpathian Basin that straddles Central and Eastern Europe. It is divided among three countries: the eastern part lies in western Romania (the counties of Timiș, Caraș-Severin, Arad south of the Mureș river, and the western part of Mehedinți); the western part of Banat is in northeastern Serbia (mostly included in Vojvodina, except for a small part included in the Belgrade Region); and a small northern part lies within southeastern Hungary (Csongrád-Csanád County).

The region's historical ethnic diversity was severely affected by the events of World War II. Today, Banat is mostly populated by ethnic Romanians, Serbs and Hungarians, but small populations of other ethnic groups also live in the region. Nearly all are citizens of either Serbia, Romania or Hungary.

The siege of Belgrade (Hungarian: Nándorfehérvár ostroma) in 1521 is an event that followed as a result of the third major Ottoman attack on this Hungarian stronghold in the Ottoman–Hungarian wars at the time of the greatest expansion of the Ottoman Empire to the west. Ottoman Sultan Suleiman the Magnificent launched his army in mid-May 1521. The Hungarian state was almost in disarray and unable to effectively counter the Ottoman army.

Uroš Predić (Serbian Cyrillic: Урош Предић, pronounced [ûrɔʃ prɛ̌ːdit͡ɕ]; Orlovat, 7 December 1857 – Belgrade, 12 February 1953) was a Serbian Realist painter. Along with Paja Jovanović and Đorđe Krstić, he is considered the most important Serbian painter of realism. Predić is best remembered for his early works, in which he depicted the "real" life of ordinary people. Later, he made a great contribution in church painting and portraits. Predić's opus includes a total of 1658 works.

The National Museum of Serbia (Serbian: Народни музеј Србије / Narodni muzej Srbije) is the largest and oldest museum in Belgrade, Serbia. It is located in the central zone of Belgrade on a square plot between the Republic Square, formerly Theatre Square, and three streets: Čika Ljubina, Vasina and Laze Pačua. Its main facade is on the Republic Square and the official address is 1a Republic Square.

The museum was established on 10 May 1844. It moved into the present building in 1950, with the grand opening of the venue on 23 May 1952. Since its founding, the museum's collection has grown to over 400,000 objects, including many foreign masterpieces.

The Church of Saint Sava (Serbian Cyrillic: Храм Светог Саве, romanized: Hram Svetog Save, lit. ''The Temple of Saint Sava'') is a Serbian Orthodox church in the Vračar plateau in Belgrade, Serbia. It is the largest Orthodox church in Serbia, one of the largest Eastern Orthodox churches and it ranks among the largest churches in the world. It is the most recognisable building in Belgrade and a landmark, as its dominating exterior resembles that of the Hagia Sophia, after which it was modelled.

The church was initially planned to serve as a cathedral, dedicated to Saint Sava, the first Serbian Archbishop and the nation's patron saint. The location at Vračar was symbolically chosen due to the Ottoman burning of Sava's relics on a pyre in 1594/95 after a Serb uprising. Construction began in 1935 after years and decades of planning, wars and political turmoil. The commission chose to base the design on the Hagia Sophia, a universally acclaimed church building. World War II and the coming Communist leadership put a halt to construction. Permission was finally granted by the Socialist Serbian government in 1984, after which construction resumed with revised construction techniques and the architectural achievement of lifting the 4,000 tonnes dome into place in June 1989.
