Slavs in the context of Household deity

Bulgaria, officially the Republic of Bulgaria, is a country in Southeast Europe. It is situated on the eastern portion of the Balkans directly south of the Danube river and west of the Black Sea. Bulgaria is bordered by Greece and Turkey to the south, Serbia and North Macedonia to the west, and Romania to the north. It covers a territory of 110,994 square kilometres (42,855 sq mi) and is the tenth largest within the European Union and the sixteenth-largest country in Europe by area. Sofia is the nation's capital and largest city; other major cities include Burgas, Plovdiv, and Varna.

One of the earliest societies in the lands of modern-day Bulgaria was the Karanovo culture (6,500 BC). In the 6th to 3rd century BC, the region was a battleground for ancient Thracians, Persians, Celts, and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asparuh, attacked from the lands of Old Great Bulgaria and permanently invaded the Balkans in the late 7th century. They established the First Bulgarian Empire, victoriously recognised by treaty in 681 AD by the Byzantine Empire. It dominated most of the Balkans and significantly influenced Slavic cultures by developing the Cyrillic script. Under the rule of the Krum's dynasty, the country rose to the status of a mighty empire and great power. The First Bulgarian Empire lasted until the early 11th century, when Byzantine emperor Basil II conquered and dismantled it. A successful Bulgarian revolt in 1185 established a Second Bulgarian Empire, which reached its apex under Ivan Asen II (1218–1241). After numerous exhausting wars and feudal strife, the empire disintegrated and in 1396 fell under Ottoman rule for nearly five centuries.

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.

South Slavs are Slavic people who speak South Slavic languages and inhabit a contiguous region of Southeast Europe comprising the eastern Alps and the Balkan Peninsula. Geographically separated from the West Slavs and East Slavs by Austria, Hungary, Romania, and the Black Sea, the South Slavs today include Bosniaks, Bulgarians, Croats, Macedonians, Montenegrins, Serbs and Slovenes.

In the 20th century, the country of Yugoslavia (from Serbo-Croatian, literally meaning "South Slavia" or "South Slavdom") united a majority of the South Slavic peoples and lands—with the exception of Bulgarians and Bulgaria—into a single state. The Pan-Slavic concept of Yugoslavia emerged in late 17th-century Croatia, at the time part of the Habsburg monarchy, and gained prominence through the 19th-century Illyrian movement. The Kingdom of Serbs, Croats and Slovenes, renamed the Kingdom of Yugoslavia in 1929, was proclaimed on 1 December 1918, following the unification of the State of Slovenes, Croats and Serbs with the kingdoms of Serbia and Montenegro. With the breakup of Yugoslavia in the early 1990s, several independent sovereign states were formed.

The early Slavs were an Indo-European peoples and speakers of the Indo-European dialectswho lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th centuries AD) in Central, Eastern and Southeast Europe and established the foundations for the Slavic nations through the Slavic states of the Early and High Middle Ages. The Slavs' original homeland is still a matter of debate due to a lack of historical records; however, scholars generally place it in Eastern Europe, with Polesia being the most commonly accepted location.

It is generally agreed that ancient Roman writers referred to the ancestors of Slavs as Venedi. The proto-Slavic term Slav shares roots with Slavic terms for speech, word, and perhaps was used by early Slavic people themselves to denote other people, who spoke languages similar to theirs. The first written use of the name "Slavs" dates to the 6th century, when the Slavic tribes inhabited a large portion of Central and Eastern Europe. By then, the nomadic Iranian-speaking peoples living in the European Pontic Steppe (the Scythians, Sarmatians, Alans, etc.) had been absorbed by the region's Slavic-speaking population. Over the next two centuries, the Slavs expanded westwards (to the Elbe river and in the Alps), and southwards (into the Balkans, absorbing Illyrian and Thracian peoples in the process), and also moved eastwards (in the direction of the Volga River). Between the sixth and seventh centuries, large parts of Europe came to be controlled or occupied by Slavs, a process less understood and documented than that of the Germanic ethnogenesis in the west. Yet the effects of Slavicization were far more profound.

The Balkan Wars were two conflicts that took place in the Balkan states in 1912 and 1913. In the First Balkan War, the four Balkan states of Greece, Serbia, Montenegro and Bulgaria declared war upon the Ottoman Empire and defeated it, in the process stripping the Ottomans of their European provinces, leaving only Eastern Thrace under Ottoman control. In the Second Balkan War, Bulgaria fought against the other four combatants of the first war. It also faced an attack from Romania from the north. The Ottoman Empire lost the bulk of its territory in Europe. Although not involved as a combatant, Austria-Hungary became relatively weaker as a much enlarged Serbia pushed for union of the South Slavic peoples. The war set the stage for the July crisis of 1914 and as a prelude to the First World War.

By the early 20th century, Bulgaria, Greece, Montenegro and Serbia had achieved independence from the Ottoman Empire, but large elements of their ethnic populations remained under Ottoman rule. Over the course of the Macedonian Struggle these states fought for influence between themselves and the Ottoman government within Ottoman Macedonia, during which their governments came under the control of nationalists. In 1912, these countries united to formed the Balkan League. The First Balkan War began on 8 October 1912, when the League member states attacked the Ottoman Empire, and ended eight months later with the signing on 30 May 1913 of the Treaty of London negotiated together with the Great Powers. The Great Powers - particularly Italy and Austria-Hungary -- included independence for Albania in the Treaty. The Second Balkan War began on 16 June 1913, when Bulgaria, dissatisfied with its allotment of territory from Macedonia, attacked its former Balkan League allies. The combined forces of the Serbian and Greek armies, with their superior numbers repelled the Bulgarian offensive and counter-attacked by invading Bulgaria from the west and the south. Romania, having taken no part in the first conflict, had intact armies to strike with and invaded Bulgaria from the north in violation of a peace treaty between the two states. The Ottoman Empire also attacked Bulgaria and advanced in Thrace, regaining Adrianople. In the resulting Treaty of Bucharest, Bulgaria managed to retain most of the territories it had gained in the First Balkan War. However, it was forced to cede the ex-Ottoman south part of Dobruja province to Romania.

Sofia is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain, in the western part of the country. The city is built west of the Iskar river and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate.

Known as Serdica in antiquity, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars, and Slavs. In 809, Serdica was incorporated into the First Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian rule until 1194, when it was reincorporated by the Second Bulgarian Empire. Sredets became a major administrative, economic, cultural and literary hub until its conquest by the Ottomans in 1382. From 1530 to 1836, Sofia was the regional capital of Rumelia Eyalet, the Ottoman Empire's largest and most important province. Bulgarian rule was restored in 1878. Sofia was selected as the capital of the Third Bulgarian State in the next year, ushering a period of intense demographic and economic growth.

The Ecumenical Patriarch of Constantinople (Greek: Οἰκουμενικός Πατριάρχης, romanized: Oikoumenikós Patriárchēs) is the archbishop of Constantinople and primus inter pares (first among equals) among the heads of the several autocephalous churches that comprise the Eastern Orthodox Church. The ecumenical patriarch is regarded as the representative and spiritual leader of the Eastern Orthodox Christians worldwide. The term ecumenical in the title is a historical reference to the Ecumene, a Greek designation for the civilised world, i.e. the Roman Empire, and it stems from Canon 28 of the Council of Chalcedon.

The patriarch's see, the Ecumenical Patriarchate of Constantinople, is one of the most enduring institutions in the world and has had a prominent part in world history. The ecumenical patriarchs in ancient times helped in the spread of Christianity and the resolution of various doctrinal disputes. In the Middle Ages, they played a major role in the affairs of the Eastern Orthodox Church, as well as in the politics of the Orthodox world, and in spreading Christianity among the Slavs. Currently, in addition to the expansion of the Christian faith and the Eastern Orthodox doctrine, the patriarchs are involved in ecumenism and interfaith dialogue, charitable work, and the defense of Orthodox Christian traditions.

Eastern Europe is a subregion of the European continent. As a largely ambiguous term, it has a wide range of geopolitical, geographical, ethnic, cultural and socio-economic connotations. Its eastern boundary is marked by the Ural Mountains, and its western boundary is defined in various ways. Narrow definitions, in which Central and Southeast Europe are counted as separate regions, include Belarus, Russia and Ukraine. In contrast, broader definitions include Moldova and Romania, but also some or all of the Balkans, the Baltic states, the Caucasus, and the Visegrád group. In Eastern Europe, Russia is the largest and most populous country.

The region represents a significant part of European culture; the main socio-cultural characteristics of Eastern Europe have historically largely been defined by the traditions of the Slavs, as well as by the influence of Eastern Christianity as it developed through the Eastern Roman Empire and the Ottoman Empire. Another definition was created by the Cold War, as Europe was ideologically divided by the Iron Curtain, with "Eastern Europe" being synonymous with communist states constituting the Eastern Bloc under the influence of the Soviet Union.

Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a 2,900-kilometer (1,800 mi) front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A–A line. The attack became the largest and costliest military offensive in human history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers.

The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it with Germans under Generalplan Ost, which planned for the removal of the native Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. The material targets of the invasion were the agricultural and mineral resources of territories such as Ukraine and Byelorussia and oil fields in the Caucasus. The Axis eventually captured five million Soviet Red Army troops on the Eastern Front and deliberately starved to death or otherwise killed 3.3 million prisoners of war, as well as millions of civilians. Mass shootings and gassing operations, carried out by German paramilitary death squads and collaborators, murdered over a million Soviet Jews as part of the Holocaust.

Hungary is a landlocked country in Central Europe. Spanning much of the Carpathian Basin, it is bordered by Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and Slovenia to the southwest, and Austria to the west. Hungary lies within the drainage basin of the Danube River and is dominated by great lowland plains. It has a population of 9.6 million, consisting mostly of ethnic Hungarians (Magyars) and a significant Romani minority. Hungarian is the official language, and among the few in Europe outside the Indo-European family. Budapest is the country's capital and largest city, and the dominant cultural and economic centre.

Prior to the foundation of the Hungarian state, various peoples settled in the territory of present-day Hungary, including the Celts, Romans, Huns, Germanic peoples, Avars and Slavs. Hungarian statehood is traced to the Principality of Hungary, which was established in the late ninth century by Álmos and his son Árpád through the conquest of the Carpathian Basin. King Stephen I ascended the throne in 1000 and converted his realm to a Christian kingdom. The medieval Kingdom of Hungary was a European power, reaching its height in the Late Middle Ages.

Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about 49,000 km (19,000 sq mi), hosting a population exceeding 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice.

The Slavs arrived in the territory of the present-day Slovakia in the 5th and 6th centuries. From the late 6th century, parts of modern Slovakia were incorporated into the Avar Khaghanate. In the 7th century, the Slavs played a significant role in the creation of Samo's Empire. When the Avar Khaghanate dissolved in the 9th century, the Slavs established the Principality of Nitra before it was annexed by the Principality of Moravia, which later became Great Moravia. When Great Moravia fell in the 10th century, the territory was integrated into the Principality of Hungary at the end of the 9th century, which later became the Kingdom of Hungary in 1000. In 1241 and 1242, after the Mongol invasion of Europe, much of the territory was destroyed, but was recovered largely thanks to Hungarian king Béla IV. During the 16th and 17th centuries, southern portions of present-day Slovakia were incorporated into provinces of the Ottoman Empire. The Ottoman-controlled areas were ceded to the Habsburgs by the turn of the 18th century. The Hungarian declaration of independence in 1848 was followed in the same year by the Slovak Uprising through the establishment of the Slovak National Council. While the uprising did not achieve its aim, it played an important role in cementing a Slovak national identity. The Hungarian wars of independence eventually resulted in a compromise that established the Austro-Hungarian Empire.

Belgrade is the capital and largest city of Serbia. It is located at the confluence of the Sava and Danube rivers and at the crossroads of the Pannonian Plain and the Balkan Peninsula. According to the 2022 census, the population of Belgrade city proper stands at 1,197,114, its contiguous urban area has 1,298,661 inhabitants, while population of city's administrative area (which roughly corresponds to its metro area) totals 1,681,405 people. It is one of the major cities of Southeast Europe and the third-most populous city on the river Danube.

Belgrade is one of the oldest continuously inhabited cities in Europe and the world. One of the most important prehistoric cultures of Europe, the Vinča culture, evolved within the Belgrade area in the 6th millennium BC. In antiquity, Thraco-Dacians inhabited the region and, after 279 BC, Celts settled the city, naming it Singidūn. It was conquered by the Romans under the reign of Augustus and awarded Roman city rights in the mid-2nd century. It was settled by the Slavs in the 520s, and changed hands several times between the Byzantine Empire, the Frankish Empire, the Bulgarian Empire, and the Kingdom of Hungary before it became the seat of the Serbian king Stefan Dragutin in 1284. Belgrade served as capital of the Serbian Despotate during the reign of Stefan Lazarević, and then his successor Đurađ Branković returned it to the Hungarian king in 1427. Noon bells in support of the Hungarian army against the Ottoman Empire during the siege in 1456 have remained a widespread church tradition to this day. In 1521, Belgrade was conquered by the Ottomans and became the seat of the Sanjak of Smederevo. It frequently passed from Ottoman to Habsburg rule, which saw the destruction of most of the city during the Ottoman–Habsburg wars.

The East Slavs are the most populous subgroup of the Slavs. They speak the East Slavic languages, and formed the majority of the population of the medieval state Kievan Rus', which they consider their cultural ancestor. Belarusians, Russians and Ukrainians are the existing East Slavic groups. Rusyns are sometimes considered a separate nation, though they are often considered a subgroup of Ukrainians.

Pan-Slavism is a political ideology that originated in the mid-19th century, emphasizing integrity and unity among the Slavic peoples. Its main impact occurred in the Balkans, where non-Slavic empires had ruled the South Slavs for centuries. These were mainly the Byzantine Empire, Austria-Hungary, the Ottoman Empire, and Venice.

The Vistula Veneti, also called Baltic Veneti, Venedi or Venethi, were an Indo-European people that inhabited the lands of central Europe east of the Vistula River and the Bay of Gdańsk. Ancient Roman geographers first mentioned Venedi in the 1st century AD, differentiating a group of peoples whose manner and language differed from those of the neighbouring Germanic and Sarmatian tribes. In the 6th century AD, Byzantine historians described the Veneti as the ancestors of the Slavs who, during the second phase of the Migration Period, crossed the northern frontiers of the Byzantine Empire.

Slavicisation or Slavicization, is the acculturation of something non-Slavic into a Slavic culture, cuisine, region, or nation. The process can either be voluntary or applied through varying degrees of pressure.

The term can also refer to the historical Slavic migrations to the Balkans which gradually Slavicized large areas previously inhabited by other ethnic peoples. In northern Russia, there was also mass Slavicization of Finnic and Baltic population in the 9th-10th centuries.

The Christianization of Bulgaria was the process by which 9th-century medieval Bulgaria converted to Christianity. It reflected the need of unity within the religiously divided Bulgarian state as well as the need for equal acceptance on the international stage in Christian Europe. This process was characterized by the shifting political alliances of Boris I of Bulgaria (ruled 852–889) with the kingdom of the East Franks and with the Byzantine Empire, as well as his diplomatic correspondence with the Pope.

Because of Bulgaria's strategic position, the churches of both Rome and Constantinople each wanted Bulgaria in their sphere of influence. They regarded Christianization as a means of integrating Slavs into their region. After some overtures to each side, the Khan adopted Christianity from Constantinople in 870. As a result, he achieved his goal of gaining an independent Bulgarian national church and having an archbishop appointed to head it.

The Slavic languages, also known as the Slavonic languages, are Indo-European languages spoken primarily by the Slavic peoples and their descendants. They are thought to descend from a proto-language called Proto-Slavic, spoken during the Early Middle Ages, which in turn is thought to have descended from the earlier Proto-Balto-Slavic language, linking the Slavic languages to the Baltic languages in a Balto-Slavic group within the Indo-European family.

The current geographical distribution of natively spoken Slavic languages includes the Balkans, Central and Eastern Europe, and all the way from Western Siberia to the Russian Far East. Furthermore, the diasporas of many Slavic peoples have established isolated minorities of speakers of their languages all over the world. The number of speakers of all Slavic languages together was estimated to be 315 million at the turn of the twenty-first century. It is the largest and most diverse ethno-linguistic group in Europe.

Sorbs (Upper Sorbian: Serbja; Lower Sorbian: Serby; German: Sorben pronounced [ˈzɔʁbn̩] ; Czech: Lužičtí Srbové; Polish: Serbołużyczanie; also known as Lusatians, Lusatian Serbs and Wends) are an indigenous West Slavic ethnic group predominantly inhabiting the parts of Lusatia located in the German states of Saxony and Brandenburg. Sorbs traditionally speak the Sorbian languages (also known as "Wendish" and "Lusatian"), which are closely related to Czech and Lechitic languages. Upper Sorbian and Lower Sorbian are officially recognized minority languages in Germany.

In the Early Middle Ages, the Sorbs formed their own principality, which later shortly became part of the early West Slavic Samo's Empire and Great Moravia, as were ultimately conquered by the East Francia (Sorbian March) and Holy Roman Empire (Saxon Eastern March, Margravate of Meissen, March of Lusatia). From the High Middle Ages, they were ruled at various times by the closely related Poles and Czechs, as well as the more distant Germans and Hungarians. Due to a gradual and increasing assimilation between the 17 and 20 centuries, virtually all Sorbs also spoke German by the early 20 century. In the newly created German nation state of the late 19 and early 20 centuries, policies were implemented in an effort to Germanize the Sorbs. These policies reached their climax under the Nazi regime, who denied the existence of the Sorbs as a distinct Slavic people by referring to them as "Sorbian-speaking Germans". The community is divided religiously between Roman Catholicism (the majority) and Lutheranism. The former Minister President of Saxony Stanislaw Tillich is of Sorbian origin.
