Slavs are the largest ethno-linguistic group in Europe. Present-day Slavic people are classified into East Slavs (chiefly Russians, Ukrainians and Belarusians), West Slavs (chiefly Poles, Czechs and Slovaks), and South Slavs (chiefly Serbs, Bulgarians, Croats, Bosniaks, Slovenes, Macedonians and Montenegrins).
Slavs can be further divided by along the lines of religion. Orthodox Christianity makes up the bulk of the religion encompassing and practiced by the Slavs. The Orthodox Slavs include the Belarusians, Bulgarians, Macedonians, Montenegrins, Russians, Serbs, and Ukrainians and are defined by their use of Orthodox customs and the use of Cyrillic script as well as their cultural influence and connection to the Byzantine Empire. The second most practiced and common religion amongst the Slavs is Roman Catholicism.
The Catholic Slavs include Croats, Czechs, Kashubians, Poles, Silesians, Slovaks and Slovenes and they are defined by their Latinate influence and heritage and connection to Western Europe. There are also substantial Protestant and Lutheran minorities (especially amongst the West Slavs).
The least common and third largest religion amongst the Slavs is Islam. Muslim Slavs include the Bosnians and other Muslims of the former Yugoslavia.
The oldest mention of the Slavic ethnonym is the 6th century AD Procopius, writing in Byzantine Greek, using various forms such as Sklaboi (Greek, Ancient (to 1453): Σκλάβοι), Sklabēnoi (Greek, Ancient (to 1453): Σκλαβηνοί), Sklauenoi (Greek, Ancient (to 1453): Σκλαυηνοί), Sthlabenoi (Greek, Ancient (to 1453): Σθλαβηνοί), or Sklabinoi (Greek, Ancient (to 1453): Σκλαβῖνοι), while his contemporary Jordanes refers to the Latin: Sclaveni in Latin. The oldest documents written in Old Church Slavonic, dating from the 9th century, attest the autonym as Slovene (Church Slavic; Old Slavonic; Church Slavonic; Old Bulgarian; Old Church Slavonic: Словѣне). These forms point back to a Slavic autonym which can be reconstructed in Proto-Slavic as, plural Slovene.
The reconstructed autonym Slavic languages: *Slověninъ is usually considered a derivation from slovo («word»), originally denoting «people who speak (the same language)», i.e. people who understand each other, in contrast to the Slavic word denoting German people, namely, meaning «silent, mute people» (from Slavic «mute, mumbling»). The word slovo («word») and the related slava («glory, fame») and slukh («hearing») originate from the Proto-Indo-European root («be spoken of, glory»), cognate with Ancient Greek, Ancient (to 1453): κλέος («fame»), whence comes the name Pericles, Latin («be called»), and English.
The Slavs under name of the Antes and the Sclaveni make their first appearance in Byzantine records in the early 6th century. Byzantine historiographers under Justinian I (527–565), such as Procopius of Caesarea, Jordanes and Theophylact Simocatta describe tribes of these names emerging from the area of the Carpathian Mountains, the lower Danube and the Black Sea, invading the Danubian provinces of the Eastern Empire.
Procopius wrote in 545 that «the Sclaveni and the Antae actually had a single name in the remote past; for they were both called Sporoi in olden times». He described them as barbarians, who lived under democracy, and that they believe in one god, «the maker of lightning» (Perun), to whom they made sacrifice. They lived in scattered housing, and constantly changed settlement. Regarding warfare, they were mainly foot soldiers with small shields and battleaxes, lightly clothed, some entering battle naked with only their genitals covered. Their language is «barbarous» (that is, not Greek-speaking), and the two tribes do not differ in appearance, being tall and robust, «while their bodies and hair are neither very fair or blond, nor indeed do they incline entirely to the dark type, but they are all slightly ruddy in color. And they live a hard life, giving no heed to bodily comforts...» Jordanes described the Sclaveni having swamps and forests for their cities. Another 6th-century source refers to them living among nearly impenetrable forests, rivers, lakes, and marshes.
Menander Protector mentions a Daurentius (577–579) that slew an Avar envoy of Khagan Bayan I. The Avars asked the Slavs to accept the suzerainty of the Avars; he however declined and is reported as saying: «Others do not conquer our land, we conquer theirs – so it shall always be for us».
The relationship between the Slavs and a tribe called the Veneti east of the River Vistula in the Roman period is uncertain. The name may refer both to Balts and Slavs.
According to eastern homeland theory, prior to becoming known to the Roman world, Slavic-speaking tribes were part of the many multi-ethnic confederacies of Eurasia – such as the Sarmatian, Hun and Gothic empires. The Slavs emerged from obscurity when the westward movement of Germans in the 5th and 6th centuries CE (thought to be in conjunction with the movement of peoples from Siberia and Eastern Europe: Huns, and later Avars and Bulgars) started the great migration of the Slavs, who settled the lands abandoned by Germanic tribes fleeing the Huns and their allies: westward into the country between the Oder and the Elbe-Saale line; southward into Bohemia, Moravia, much of present-day Austria, the Pannonian plain and the Balkans; and northward along the upper Dnieper river. Perhaps some Slavs migrated with the movement of the Vandals to Iberia and North Africa.
Around the 6th century, Slavs appeared on Byzantine borders in great numbers. The Byzantine records note that grass would not regrow in places where the Slavs had marched through, so great were their numbers.
After a military movement even the Peloponnese and Asia Minor were reported to have Slavic settlements. This southern movement has traditionally been seen as an invasive expansion. By the end of the 6th century, Slavs had settled the Eastern Alps regions.
When their migratory movements ended, there appeared among the Slavs the first rudiments of state organizations, each headed by a prince with a treasury and a defense force. Moreover, it was the beginning of class differentiation, and nobles pledged allegiance either to the Frankish/Holy Roman Emperors or the Byzantine Emperors.
In the 7th century, the Frankish merchant Samo, who supported the Slavs fighting their Avar rulers, became the ruler of the first known Slav state in Central Europe, which, however, most probably did not outlive its founder and ruler. This provided the foundation for subsequent Slavic states to arise on the former territory of this realm with Carantania being the oldest of them. Very old also are the Principality of Nitra and the Moravian principality (see under Great Moravia). In this period, there existed central Slavic groups and states such as the Balaton Principality, but the subsequent expansion of the Magyars, as well as the Germanisation of Austria, separated the northern and southern Slavs. The First Bulgarian Empire was founded in 681, and the Slavic language Old Church Slavonic became the main and official of the empire in 864. Bulgaria was instrumental in the spread of Slavic literacy and Christianity to the rest of the Slavic world.
As of 1878, there were only three free Slavic states in the world: the Russian Empire, Serbia and Montenegro. Bulgaria was also free but was de jure vassal to the Ottoman Empire until official independence was declared in 1908. In the entire Austro-Hungarian Empire of approximately 50 million people, about 23 million were Slavs. The Slavic peoples, who were, for the most part, denied a voice in the affairs of the Austria-Hungary, were calling for national self-determination. Because of the vastness and diversity of the territory occupied by Slavic people, there were several centers of Slavic consolidation. In the 19th century, Pan-Slavism developed as a movement among intellectuals, scholars, and poets, but it rarely influenced practical politics and did not find support in some Slavic nations. Pan-Slavism became compromised when the Russian Empire started to use it as an ideology justifying its territorial conquests in Central Europe as well as subjugation of other Slavic ethnic groups such as Poles and Ukrainians, and the ideology became associated with Russian imperialism.
During World War I, representatives of the Czechs, Slovaks, Poles, Serbs, Croats, and Slovenes set up organizations in the Allied countries to gain sympathy and recognition. In 1918, after World War I ended, the Slavs established such independent states as Czechoslovakia, the Second Polish Republic, and the State of Slovenes, Croats and Serbs (which merged into Yugoslavia).
During World War II, Nazi Germany planned to kill, deport, or enslave the Slavic population of occupied Eastern Europe to create Living space for German settlers, and also planned the starvation of 80 million people in the Soviet Union.
The first half of the 20th century in Russia and the Soviet Union was marked by a succession of wars, famines and other disasters, each accompanied by large-scale population losses. Stephen J. Lee estimates that, by the end of World War II in 1945, the Russian population was about 90 million fewer than it could have been otherwise.
The common Slavic experience of communism combined with the repeated usage of the ideology by Soviet propaganda after World War II within the Eastern bloc (Warsaw Pact) was a forced high-level political and economic hegemony of the USSR dominated by Russians. A notable political union of the 20th century that covered most South Slavs was Yugoslavia, but it ultimately broke apart in the 1990s along with the Soviet Union.
The word «Slavs» was used in the national anthem of Yugoslavia (1943–1992) and the Federal Republic of Yugoslavia (1992–2003), later Serbia and Montenegro (2003–2006).
Former Soviet states, as well as countries that used to be satellite states or territories of the Warsaw Pact, have numerous minority Slavic populations, many of whom are originally from the Russian SFSR, Ukrainian SSR and Byelorussian SSR. As of now, Kazakhstan has the largest Slavic minority population with most being Russians (Ukrainians, Belarusians and Poles are present as well but in much smaller numbers).
Pan-Slavism, a movement which came into prominence in the mid-19th century, emphasized the common heritage and unity of all the Slavic peoples. The main focus was in the Balkans where the South Slavs had been ruled for centuries by other empires: the Byzantine Empire, Austria-Hungary, the Ottoman Empire, and Venice. The Russian Empire used Pan-Slavism as a political tool; as did the Soviet Union, which gained political-military influence and control over most Slavic-majority nations between 1945 and 1948 and retained a hegemonic role until the period 1989–1991.
Proto-Slavic, the supposed ancestor language of all Slavic languages, is a descendant of common Proto-Indo-European, via a Balto-Slavic stage in which it developed numerous lexical and morph phonological isoglosses with the Baltic languages. In the framework of the Kurgan hypothesis, «the Indo-Europeans who remained after the migrations [from the steppe] became speakers of Balto-Slavic». Proto-Slavic is defined as the last stage of the language preceding the geographical split of the historical Slavic languages. That language was uniform, and on the basis of borrowings from foreign languages and Slavic borrowings into other languages, cannot be said to have any recognizable dialects – this suggests that there was, at one time, a relatively small Proto-Slavic homeland.
Slavic linguistic unity was to some extent visible as late as Old Church Slavonic manuscripts which, though based on local Slavic speech of Thessaloniki, could still serve the purpose of the first common Slavic literary language. Slavic studies began as an almost exclusively linguistic and philological enterprise. As early as 1833, Slavic languages were recognized as Indo-European. Sometimes the West Slavic and East Slavic languages are combined into a single group known as North Slavic languages.
Standardized Slavic languages that have official status in at least one country are: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Macedonian, Montenegrin, Polish, Russian, Serbian, Slovak, Slovene, and Ukrainian.
The alphabets used for Slavic languages are frequently connected to the dominant religion among the respective ethnic groups. Orthodox Christians use the Cyrillic alphabet while Roman Catholics use the Latin alphabet; the Bosnians, who are Muslim, also use the Latin alphabet. Additionally, some Eastern Catholics and Roman Catholics use the Cyrillic alphabet. Serbian and Montenegrin use both the Cyrillic and Latin alphabets. There is also a Latin script to write in Belarusian, called the Lacinka alphabet.
Slavs are customarily divided along geographical lines into three major subgroups: West Slavs, East Slavs, and South Slavs, each with a different and a diverse background based on unique history, religion and culture of particular Slavic groups within them. Apart from prehistorical archaeological cultures, the subgroups have had notable cultural contact with non-Slavic Bronze- and Iron Age civilizations. Modern Slavic nations and ethnic groups are considerably diverse both genetically and culturally, and relations between them – even within the individual ethnic groups themselves – are varied, ranging from a sense of connection to mutual feelings of hostility.
West Slavs have origin in early Slavic tribes which settled in Central Europe after East Germanic tribes had left this area during the migration period. They are noted as having mixed with Germanics, Hungarians, and to a lesser extent, Balts. The West Slavs came under the influence of the Western Roman Empire (Latin) and of the Roman Catholic Church.
East Slavs have origins in early Slavic tribes who mixed with Finno-Ugric peoples and Balts. Their early Slavic component, Antes, mixed or absorbed Iranians, and later received influence from the Khazars and Vikings. The East Slavs trace their national origins to the tribal unions of Kievan Rus', beginning in the 10th century. They came particularly under the influence of the Eastern Roman Empire (Byzantine Empire) and of the Eastern Orthodox Church; Eastern Catholic Churches later became established in the 16th century in areas such as Ukraine.
South Slavs from most of the region have origins in early Slavic tribes who mixed with the local Proto-Balkanic tribes (Illyrian, Dacian, Thracian, Paeonian and Hellenic tribes), Celtic tribes (most notably the Scordisci), as well as with Romans (and the Romanized remnants of the former groups), and also with remnants of temporarily settled invading East Germanic, Asiatic or Caucasian tribes such as Gepids, Huns, Avars and Bulgars. The original inhabitants of present-day Slovenia and continental Croatia have origins in early Slavic tribes who mixed with Romans and romanized Celtic and Illyrian people as well as with Avars and Germanic peoples (Lombards and East Goths). The South Slavs (except the Slovenes and Croats) came under the cultural sphere of the Eastern Roman Empire(Byzantine Empire), of the Ottoman Empire and of the Eastern Orthodox Church and Islam, while the Slovenes and the Croats were influenced by Western Roman Empire (Latin), Holy Roman Empire and, thus by the Roman Catholic Church.
The pagan Slavic populations were Christianized between the 10th and 14th centuries. Orthodox Christianity is predominant in the East and South Slavs, while Roman Catholicism is predominant in West Slavs and the western South Slavs. The religious borders are largely comparable to the East–West Schism which began in the 11th century.
The majority of contemporary Slavic populations who profess a religion are Orthodox, followed by Catholic, while small minorities are Protestant. There are minor Slavic Muslim groups. Religious delineations by nationality can be very sharp; usually in the Slavic ethnic groups the vast majority of religious people share the same religion. Some Slavs are atheist or agnostic: in the Czech Republic 20% were atheists according to a 2012 poll.
Relations with non-Slavic people
Throughout their history, Slavs came into contact with non-Slavic groups. In the postulated homeland region (present-day Ukraine), they had contacts with the Iranic Sarmatians and the Germanic Goths. After their subsequent spread, the Slavs began assimilating non-Slavic peoples. For example, in the Balkans, there were Paleo-Balkan peoples, such as Romanized and Hellenized (Jireček Line) Illyrians, Thracians and Dacians, as well as Greeks and Celtic Scordisci. Over time, due to the larger number of Slavs, most descendants of the indigenous populations of the Balkans were Slavicized. The Thracians and Illyrians vanished as defined ethnic groups from the population during this period – although the modern Albanian nation claims descent from the Illyrians. Exceptions are Greece, where because Slavs were fewer than Greeks, they came to be Hellenized (aided in time by more Greeks returning to Greece in the 9th century and the role of the church and administration); and Romania, where Slavic people settled end route for present-day Greece, Republic of Macedonia, Bulgaria and East Thrace, where the Slavic population gradually assimilated.
Ruling status of Bulgars and subsequent control of land cast the nominal legacy of Bulgarian country and people onto future generations, but Bulgars were gradually also Slavicized into the present day South Slavic ethnic group Bulgarians. The Romance speakers within the fortified Dalmatian cities managed to retain their culture and language for a long time. Dalmatian Romance was spoken until the high middle Ages. But, they too were eventually assimilated into the body of Slavs.
In the Western Balkans, South Slavs and Germanic Gepids intermarried with Avar invaders, eventually producing a Slavicized population. In Central Europe, the Slavs intermixed with Germanic and Celtic peoples, while the eastern Slavs encountered Uralic and Scandinavian peoples. Scandinavians (Varangians) and Finnish peoples were involved in the early formation of the Rus' state but were completely Slavicized after a century. Some Finno-Ugric tribes in the north were also absorbed into the expanding Rus population. At the time of the Magyar migration, the present-day Hungary was inhabited by Slavs, numbering about 200,000, and by Romano-Dacians who were either assimilated or enslaved by the Magyars. In the 11th and 12th centuries, constant incursions by nomadic Turkic tribes, such as the Kipchak and the Pecheneg, caused a massive migration of East Slavic populations to the safer, heavily forested regions of the north. In the middle Ages, groups of Saxon are miners settled in medieval Bosnia, Serbia and Bulgaria, where they were Slavicized.
Polabian Slavs (Wends) settled in eastern parts of England (the Danelaw), apparently as Danish allies. Polabian-Pomeranian Slavs are also known to have even settled on Norse age Iceland. Saqaliba refers to the Slavic mercenaries and slaves in the medieval Arab world in North Africa, Sicily and Al-Andalus. Saqaliba served as caliph's guards. In the 12th century, Slavic piracy in the Baltics increased. The Wendish Crusade was started against the Polabian Slavs in 1147, as a part of the Northern Crusades. Niklot, pagan chief of the Slavic Obodrites, began his open resistance when Lothar III, Holy Roman Emperor, invaded Slavic lands. In August 1160 Niklot was killed, and German colonization (Ostsiedlung) of the Elbe-Oder region began. In Hanoverian Wend land, Mecklenburg-Vorpommern and Lusatia, invaders started germanization. Early forms of germanization were described by German monks: Helmold in the manuscript Chronic on Slavorum and Adam of Bremen Gesta Hammaburgensis. The Polabian language survived until the beginning of the 19th century in what is now the German state of Lower Saxony. In Eastern Germany, around 20% of Germans have historic Slavic paternal ancestry, as revealed in Y-DNA testing. Similarly, in Germany, around 20% of the foreign surnames are of Slavic origin
