The early Slavs were a diverse group of tribal societies who lived during the Migration Period and Early Middle Ages (approximately the fifth to the tenth centuries) in Eastern Europe and established the foundations for the Slavic nations through the Slavic states of the High Middle Ages.[need quotation to verify] The first written use of the name "Slavs" dates to the sixth century, when the Slavic tribes inhabited a large portion of Central and Eastern Europe. By that century, native Iranian ethnic groups (the Scythians, Sarmatians, and Alans) had been absorbed by the region's Slavic population. Over the next two centuries, the Slavs expanded southwest toward the Balkans and the Alps and northeast towards the Volga River.
Beginning in the ninth century, the Slavs gradually converted to Christianity (both Byzantine Orthodoxy and Roman Catholicism). By the 12th century, they were the core population of a number of medieval Christian states: the East Slavs in Kievan Rus', the South Slavs in Bulgaria, Croatia, Bosnia and Serbia and the West Slavs in Poland, the Holy Roman Empire (Pomerania, Bohemia, Moravia) and the Kingdom of Hungary (Nitria).
The meaning of "Slav" depends on the context in which it is used. The word can refer to a culture (or cultures) living north of the River Danube, east of the River Elbe, and west of the River Vistula during the 530s CE. "Slav" is also an identifier for the ethnic group shared by these cultures, and denotes any language with linguistic ties to the modern Slavic language family (which may have no connection to a common culture or shared ethnicity). Despite these concepts of "Slav", it is unclear whether any of the descriptions add to an accurate representation of the group's history; historians such as George Vernadsky, Florin Curta, and Michael Karpovich have questioned how, why, and to what degree the Slavs were a cohesive society between the sixth and ninth centuries. When discussing evidence used to construct a history of the Slavs, the information fall into three avenues of research: archeological, historiographic, and linguistic.
Archaeologically, early Slavic physical evidence ranges from hill forts, ceramic pots and fragments to abodes. However, archaeologists face difficulties distinguishing Slavic and non-Slavic findings. Many of these findings are inaccurately radiocarbon-dated or so isolated that they do not reflect organized Slavic settlement.
Although a number of sources describe the Slavs, there are several problems with using the texts to build upon available knowledge of the early Slavs. Useful historical information about the Slavs from them is cryptic or does not identify their source. The works tend to discuss the Slavs only in terms of their effects on surrounding empires, particularly the Byzantines and the Franks. The variety of names referring to the Slavs, such as Antes, Sclaveni, and Venethi, and the regions they may have occupied make it difficult to establish geographical boundaries of major settlement. Place names have changed, or no longer survive, and most texts are second-hand accounts or describe an encounter with the Slavs years, decades, or centuries after it occurred. Earlier texts contextualize the Slavs' early history and development, but those written long after an event are less reliable.
Linguistic study of Slavic history has focused on three main areas: place names, the names of flora and fauna, and "lexical and structural similarities and differences between Slavic and other languages". The Slavs were described by their neighbors as Antes, Sclaveni, and Venethi in texts written during and after the 500s. The concept of ethnicity during this period was fluid; more than one ethnicity would be ascribed to a group, depending on the circumstances of the encounter (such as Michal Parczewski's map). This map of Slavic settlement during the 6th century relative to their neighbors drawn from written fragments, omits source information which contradicted Parczewski's conclusions. The association by archaeologists of pot and burial styles with ethnonyms and the selective use of historical materials assumes a connection between language and ethnicity. Ethnic identification can be subjective, especially in a region where many tribal groups identified themselves as distinct from one another.
The history of the early Slavs is inseparable from political agendas underlying much 19th- and 20th-century archaeological, linguistic, and historiographic research. According to Florin Curta, the creation of such a history "was a function of both ethnic formation and ethnic identification". The process was blurred by a number of interests, including Pan-Slavic researchers in Central and Eastern Europe during the 18th and 19th centuries, European nations strengthening their legitimacy after World War II, and a contemporary politicization of historical, archaeological, and linguistic discourse.
The Slavic languages, with about 300 million speakers in 2006, are a major branch of the Indo-European language family. All known Slavic languages share a number of features (including a much of their vocabulary), which suggests that they evolved from mutually intelligible dialects spoken in a "relatively restricted core area". Although the former common language (known as Proto- or Common Slavonic) is not attested in written sources, it can be reconstructed by studying its daughter languages. The similarities among the daughter languages indicate that Common Slavonic was spoken during recorded history, with its division into daughter languages beginning in the 9th century AD.
The Proto-Slavic homeland is the area of Slavic settlement in Central and Eastern Europe during the first millennium AD, with its precise location debated by archaeologists, ethnographers and historians. Theories attempting to place Slavic origin in the Near East have been discarded. None of the proposed homelands reaches the Volga River in the east, over the Dinaric Alps in the southwest or the Balkan Mountains in the south, or past Bohemia in the west.
Frederick Kortlandt has suggested that the number of candidates for Slavic homeland may rise from a tendency among historians to date "proto-languages farther back in time than is warranted by the linguistic evidence"; although all spoken languages change gradually over time, in the absence of written records that change can be identified by historians only after a population has expanded and separated long enough to develop daughter languages. The existence of an "original home" is sometimes rejected as arbitrary, because the earliest origin sources "always speak of origins and beginnings in a manner which presupposes earlier origins and beginnings".
According to historical records, the Slavic homeland would have been somewhere in central Europe (possibly along the southern shore of the Baltic Sea. The Prague-Penkov-Kolochin complex of cultures during the sixth and seventh centuries AD is generally accepted to reflect the expansion of Slavic speakers at the time. Core candidates are cultures within the territories of modern Belarus, Poland, and Ukraine. According to Polish historian Gerard Labuda, the ethnogenesis of Slavic people is the Trzciniec culture from about 1700 to 1200 BC. The Milograd culture hypothesis posits that the pre-Proto-Slavs (or Balto-Slavs) originated in the seventh century BC–first century AD culture of northern Ukraine and southern Belarus. According to the Chernoles culture theory, the pre-Proto-Slavs originated in the 1025–700 BC culture of northern Ukraine and the third century BC–first century AD Zarubintsy culture. According to the Lusatian culture hypothesis, they were present in north-eastern Central Europe in the 1300–500 BC culture and the second century BC–fourth century AD Przeworsk culture. The Danube basin hypothesis, postulated by Oleg Trubachyov and supported by Florin Curta and Nestor's Chronicle, theorizes that the Slavs originated in central and southeastern Europe.
Proto-Slavonic began to evolve from Proto-Indo-European, the reconstructed language from which a number of languages spoken in Eurasia originated.  Slavic languages share a number of features with Baltic languages (including the use of genitive case for the objects of negative sentences, Proto-Indo-European kʷ and other labialized velars), which may indicate a common Proto-Balto-Slavic phase in the development of the two of the Indo-European linguistic branches. Frederick Kortlandt places the territory of this common language near the Indo-European homeland: "The Indo-Europeans who remained after the migrations became speakers of Balto-Slavic". However, "geographical contiguity, parallel development and interaction" may explain the existence of these language-group characteristics.
Proto-Slavonic developed into a separate language during the first half of the second millennium BC. The Proto-Slavonic vocabulary, inherited by its daughter languages, described its speakers' physical and social environment, feelings and needs. Proto-Slavonic had words for family connections, including svekry ("husband's mother"), and zъly ("sister-in-law"). Inherited Common Slavic vocabulary lacks detailed terminology for physical surface features peculiar to mountains or the steppe, the sea, coastal features, littoral flora or fauna, or saltwater fish.
Proto-Slavonic hydronyms have been preserved between the source of the Vistula and the middle basin of the Dnieper. Its northern regions adjoin territory where river names of Baltic origin (Daugava, Nemunas and others) abound. On the south and east, it borders the area of Iranian river names (including the Dniester, the Dnieper and the Don). A connection between Proto-Slavonic and Iranian languages is also demonstrated by the earliest layer of loanwords in the former; the Proto-Slavonic words for god (*bogъ), demon (*divъ), house (*xata), axe (*toporъ) and dog (*sobaka) are of Scythian origin. The Iranian dialects of the Scythians and Sarmatians influenced Slavic vocabulary during the millennium-long contact between them and early Proto-Slavic.
A longer, more intensive connection between Proto-Slavonic and the Germanic languages can be assumed from the number of Germanic loanwords, such as *duma ("thought"), *kupiti ("to buy"), *mĕčь ("sword"), *šelmъ ("helmet"), and *xъlmъ ("hill"). The Common Slavonic words for beech, larch and yew were also borrowed from Germanic, which led Polish botanist Józef Rostafiński to place the Slavic homeland in the Pripet Marshes (where the plants were missing). Germanic languages were a mediator between Common Slavonic and other languages; the Proto-Slavonic word for emperor (*cĕsar'ь) was transmitted from Latin through a Germanic idiom, and the Common Slavonic word for church (*crъky) came from Greek.
Common Slavic dialects before the fourth century AD cannot be detected; all daughter languages emerged from later variants. Tonal word stress (a ninth-century change) is present in all Slavic languages, and Proto-Slavonic reflects the language probably spoken at the end of the first millennium.
Jordanes, Procopius and other late Roman authors provide the probable earliest references to southern Slavs in the second half of the sixth century. Jordanes completed his Gothic History (an abridgement of Cassiodorus' longer work) in Constantinople in 550 or 551. He also used additional sources: books, maps or oral tradition.
Jordanes wrote that Venethi, Sclavenes and Antes were ethnonyms referring to the same group. His claim was accepted more than a millennium later by Wawrzyniec Surowiecki, Pavel Jozef Šafárik and other historians, who searched the Slavic Urheimat in the lands where the Venethi (a people named in Tacitus's Germania) lived during the last decades of the first century AD. Pliny the Elder wrote that the territory extending from the Vistula to Eningia (probably Feningia, or Finland), was inhabited by the Sarmati, Wends, Scirii and Hirri.
Procopius completed his three works on Emperor Justinian I's reign (Buildings, History of the Wars, and Secret History) during the 550s. Each book contains detailed information on raids by Sclavenes and Antes on the Eastern Roman Empire, and the History of the Wars has a comprehensive description of their beliefs, customs, and dwellings. Although not an eyewitness, Procopius had contacts among the Sclavene mercenaries fighting on the Roman side in Italy.
Agreeing with Jordanes's report, Procopius wrote that the Sclavenes and Antes spoke the same languages but traced their common origin not to the Venethi but to a people he called "Sporoi". Sporoi ("seeds" in Greek; compare "spores") is equivalent to the Latin semnones and germani ("germs" or "seedlings"). German linguist Jacob Grimm believed that Suebi meant "Slav".  Jordanes and Procopius called the Suebi "Suavi". The end of the Bavarian Geographer's list of Slavic tribes contains a note, "Suevi are not born, they are sown (seminati)". The language spoken by Tacitus' Suevi is unknown. In his description of the emigration (c. 512) of the Heruli to Scandinavia, Procopius places the Slavs in Central Europe.
A similar description of the Sclavenes and Antes is found in the Strategikon of Maurice, a military handbook written between 592 and 602 and attributed to the Byzantine emperor. Its author, an experienced officer, participated in the Eastern Roman campaigns against the Sclavenes on the lower Danube at the end of the century. A military staff member was also the source of Theophylact Simocatta's narrative of the same campaigns.
Although Martin of Braga was the first Western author to refer to a people known as "Sclavus" before 580, Jonas of Bobbio included the earliest lengthy record of the nearby Slavs in his Life of Saint Columbanus (written between 639 and 643). Jonas referred to the Slavs as "Veneti", noting that they were also known as "Sclavi".
Western authors, including Fredegar and Boniface, preserved the term "Venethi". The Franks (in the Life of Saint Martinus, the Chronicle of Fredegar and Gregory of Tours), Lombards (Paul the Deacon) and Anglo-Saxons (Widsith) referred to Slavs in the Elbe-Saale region and Pomerania as "Wenden" or "Winden" (see Wends). The Franks and Bavarians of Styria and Carinthia called their Slavic neighbours "Windische".
The unknown author of the Chronicle of Fredegar used the word "Venedi" (and variants) to refer to a group of Slavs who were subjugated by the Avars. In the chronicle, "Venedi" formed a state which emerged from a revolt led by the Frankish merchant Samo against the Avars around 623. A change in terminology, the appearance of Slavic tribal names instead of the collective "Sclavenes" and "Antes", occurred at the end of the century; the first tribal names were recorded in the second book of the Miracles of Saint Demetrius, around 690. According to Florin Curta, the change indicates pre-existing differences among Slavic groups; although "Sclavene" may have originally been the ethnonym of a particular ethnic group, it became "a purely Byzantine construct ... an umbrella term for various groups living north of the Danube frontier, which were neither 'Antes', nor 'Huns' or 'Avars'." The unknown "Bavarian Geographer" listed Slavic tribes in the Frankish Empire around 840, and a detailed description of 10th-century tribes in the Balkan Peninsula was compiled under the auspices of Emperor Constantine VII Porphyrogenitus in Constantinople around 950.
In the archaeological literature, attempts have been made to assign an early-Slavic character to several cultures in a number of time periods and regions The Prague-Korchak cultural horizon encompasses postulated early-Slavic cultures from the Elbe to the Dniester, in contrast with the Dniester-to-Dnieper Penkovka culture. "Prague culture" refers to western Slavic material grouped around Bohemia, Moravia and western Slovakia, distinct from the Mogilla (southern Poland) and Korchak (central Ukraine and southern Belarus) groups further east. The Prague and Mogilla groups are seen as the archaeological reflection of sixth-century western Slavs.
The second-to-fifth-century Chernyakhov culture encompassed modern Ukraine, Moldova and Wallachia. Chernyakov finds include polished black-pottery vessels, fine metal ornaments and iron tools. Soviet scholars, such as Boris Rybakov, saw it as the archaeological reflection of the proto-Slavs. The Chernyakov zone is now seen as representing the cultural interaction of several peoples, one of which was rooted in Scytho-Sarmatian traditions, modified by Germanic elements introduced by the Goths. The semi-subterranean dwelling with a corner hearth later became typical of early Slavic sites, with Volodymir Baran calling it a Slavic "ethnic badge". In the Carpathian foothills of Podolia, at the northwestern fringes of the Chernyakov zone, the Slavs gradually became a culturally-unified people; the multi-ethnic environment of the Chernyakhov zone presented a "need for self-identification in order to manifest their differentiation from other groups".
The Przeworsk culture, northwest of the Chernyakov zone, extended from the Dniester to the Tisza valley and north to the Vistula and Oder. It was an amalgam of local cultures, most with roots in earlier traditions modified by influences from the (Celtic) La Tène culture, (Germanic) Jastorf culture beyond the Oder and the Bell-Grave culture of the Polish plain. The Venethi may have played a part; other groups included the Vandals, Burgundians and Sarmatians. East of the Przeworsk zone was the Zarubinets culture, sometimes considered part of the Przeworsk complex. Early Slavic hydronyms are found in the area occupied by the Zarubinets culture, and Irena Rusinova proposed that the most prototypical examples of Prague-type pottery later originated there. The Zarubinets culture is identified as proto-Slavic or an ethnically-mixed community which became Slavicized.
With increasing age, the confidence with which archaeological connections can be made to known historic groups lessens. The Chernoles culture has been seen as a stage in the evolution of the Slavs, and Marija Gimbutas identified it as the proto-Slavic homeland. According to many pre-historians, ethnic labels are inappropriate for European Iron Age peoples.
The Globular Amphora culture stretched from the middle Dnieper to the Elbe during the late fourth and early third millennia BC. It has been suggested as the locus of a Germano-Balto-Slavic continuum (the Germanic substrate hypothesis), but the identification of its bearers as Indo-Europeans is uncertain. The area of this culture contains a number of tumuli, typical of Indo-Europeans.
The eighth-to-third-century BC Chernoles culture, sometimes associated with Herodotus' "Scythian farmers", is "sometimes portrayed as either a state in the development of the Slavic languages or at least some form of late Indo-European ancestral to the evolution of the Slavic stock." The Milograd culture (700 BC–100 AD), centered roughly in present-day Belarus and north of the Chernoles culture, has also been proposed as ancestral for the Slavs or the Balts. The ethnic composition of the Przeworsk culture (second century BC–fourth century AD), associated with the Lugii) of central and southern Poland, northern Slovakia and Ukraine, including the Zarubintsy culture (second century BC–second century AD and connected with the Bastarnae tribe) and the Oksywie culture are other candidates.
Southern Ukraine is known to have been inhabited by Scythian and Sarmatian tribes before the Goths. Early Slavic stone stelae found in the middle Dniester region are markedly different from the Scythian and Sarmatian stelae of the Crimea.
The Wielbark culture displaced the eastern Oksywie culture during the first century AD. Although the second-to-fifth-century Chernyakhov culture triggered the decline of the late Sarmatian culture from the second to fourth centuries, the western part of the Przeworsk culture remained intact until the fourth century and the Kiev culture flourished from the second to the fifth centuries. The latter is recognized as the predecessor of the sixth- and seventh-century Prague-Korchak and Pen'kovo cultures, the first archaeological cultures identified as Slavic. Although Proto-Slavic probably reached its final stage in the Kiev area, there is disagreement in the scientific community about the Kiev culture's predecessors; some scholars trace it from the Ruthenian Milograd culture, others from the Ukrainian Chernoles and Zarubintsy cultures and still others from the Polish Przeworsk culture.
The Slavic population of eastern Europe expanded during the sixth century, bringing their customs and language. Although there is no consensus about their homeland, scholars generally looked north of the Carpathians. Russian archaeologist Valentin Sedov, using the Herderian concept of nationhood, proposed that the Venethi were the proto-Slavic bearers of the Przeworsk culture. Their expansion began during the second century AD, and they occupied a large area of eastern Europe between the Vistula and the middle Dneiper. The Venethi slowly expanded south and east by the fourth century, assimilating the neighbouring Zarubinec culture (which Sedov considered partly Baltic) and continuing southeast to become part of the Chernyakhov culture. The Antes separated themselves from the Venethi by 300 (followed by the Sclaveni by 500) in the areas of the Pen’kovka and Prague-Korchak cultures, respectively. In 2003, Walter Pohl wrote:
The hypothesis of an ancient Slavic people that spread through migration had always appealed Slav nationalists, and is still widely held, but there is little sound evidence to recommend it. Most of all, it fails to make plausible why a regional and hitherto virtually unknown group could take over almost the whole of eastern and east central Europe in a relatively short period from c. 500 to c. 650 A.D.
During the seventh century BC, the Chernoles culture was loosely governed by the Scythians via trade. There was limited interaction between the Slavs, who were tribute-paying Scythian ploughmen, and the nomads. Their homeland in the forest steppe enabled them to preserve their language, except for phonetic and some lexical constituents (Satemisation) and their patrilineal, agricultural customs. After a millennium, when the Hunnic Empire collapsed, an eastern-Slavic culture re-emerged and spread rapidly in south- and central-eastern Europe. According to Marija Gimbutas, "Neither Bulgars nor Avars colonized the Balkan Peninsula; after storming Thrace, Illyria and Greece they went back to their territory north of the Danube. It was the Slavs who did the colonizing ... entire families or even whole tribes infiltrated lands. As an agricultural people, they constantly sought an outlet for the population surplus. Suppressed for over a millennium by foreign rule of Scythians, Sarmatians and Goths, they had been restricted to a small territory; now the barriers were down and they poured out". In addition to their growth, the depopulation of eastern Europe (due, in part, to Germanic migration) and the lack of imperial defences encouraged Slavic expansion.
With processual archaeology during the 1960s, scholars began to believe that "there was no need to explain culture change exclusively in terms of migration and population replacement". According to historical linguist Johanna Nichols, "Ethnic spreads can involve either the spread of a language to speakers of other languages or the spread of a population. Massive population spread or demographic replacement has probably been a rarity in human history ... [T]here is no reason to assume that the Slavic expansion was a primarily demographic event. Some migration took place, but the parsimonious assumption is the Slavic expansion was primarily a linguistic spread". Renfrew proposed elite-dominance and system-collapse theories to explain language replacement.
Dolukhanov suggested that their experience with nomads enabled the Slavs political and military experience, becoming a "dominant force and establishing a new socio-political network in the entire area of central and southeastern Europe". According to Paul Barford, "The spartan and egalitarian (Slavic) culture ... clearly had something attractive for great numbers of the populations living over considerable areas of central Europe", resulting in their assimilation. "The analysis of Slav material culture (especially South Slavs) and results of anthropological investigations, as well as the loan-words in philological studies, clearly demonstrate the contribution of the previous populations of these territories in the make-up of some of the Slav populations".
Byzantine chroniclers noted that Roman prisoners captured by the Sclavenes could soon become free members of Slavic society if they wished. Horace Lunt attributed Slavic spread to the "success and mobility of the Slavic 'special border guards' of the Avar khanate", (military elites, who used it as a lingua franca in the Avar Khanate. According to Lunt, only as a lingua franca could Slavic supplant other languages and dialects whilst remaining relatively uniform. Although it explains the formation of regional Slavic groups in the Balkans, eastern Alps and the Morava-Danube basin, Lunt's theory does not account for Slavic spread to the Baltic region and the territory of the Eastern Slavs (areas with no historical links to the Avar Khanate):
A concept related to elite dominance is system collapse, where a power vacuum created by the fall of the Hun and Roman Empires allows a minority group to impose their customs and language. Paul Barford suggested that Slavic groups might have existed in a wide area of central-eastern Europe (in the Chernyakov and Zarubintsy-Przeworsk cultural zones) before the documented Slavic migrations from the sixth to the ninth centuries. Serving as auxiliaries in the Sarmatian, Goth and Hun armies, small numbers of Slavic speakers might have reached the Balkans before the sixth century: These scattered groups were centers for the creation of a Slavic cultural identity under favorable conditions, assimilating or conveying their culture and language.
A similar idea has been proposed by Florin Curta. Seeing no clear evidence for a migration from Polesia or elsewhere north, Curta suggests that southeastern Europe saw the development of a "broad area of common economic and cultural traditions ... Whether living within the same region or widely scattered, adherence to this style helped to integrate isolated individuals within a group whose social boundaries criss-crossed those of local communities". "During the early 600s, however, at the time of the general collapse of the Byzantine administration in the Balkans, access to and manipulation of such (Slavic) artifacts may have been strategies for creating a new sense of identity for local elites". Curta suggests that the chief impetus for this identity originated in the Danubian frontier.
Scholars acknowledge that an attempt to define a localized Slavic homeland may be simplistic. Although proto-Slavic may have developed in a localized area, Slavic ethnogenesis occurred in a large area, from the Oder in the west to the Dnieper in the east and south to the Danube. It was a complex process, fueled by changes in the barbaricum and the Roman Empire. Despite cultural uniformity, Slavic development seems to have been less politically consolidated than that of the Germanic peoples.
According to Patrick Geary, Slavic expansion was a decentralized-but-forceful process which assimilated a large population with small groups of "soldier-farmers" who had common traditions and language: "Without kings or large–scale chieftains to bribe or defeat, the Byzantine Empire had little hope of either destroying them or co-opting them into the imperial system". Walter Pohl agrees: "Avars and Bulgars conformed to the rules of the game established by the Romans. They built up a concentration of military power that was paid, in the last resort, from Roman tax revenues. Therefore they paradoxically depended on the functioning of the Byzantine state. The Slavs managed to keep up their agriculture (and a rather efficient kind of agriculture, by the standards of the time), even in times when they took their part in plundering Roman provinces. The booty they won apparently did not (at least initially) create a new military class with the greed for more and a contempt for peasant's work, as it did with the Germans. Thus the Slavic model proved an attractive alternative ... which proved practically indestructible. Slav traditions, language, and culture shaped, or at least influenced, innumerable local and regional communities: a surprising similarity that developed without any central institution to promote it. These regional ethnogeneses inspired by Slavic tradition incorporated considerable remnants of Roman or Germanic population ready enough to give up ethnic identities that had lost their cohesion".
Barford cited Procopius as writing that the Slavs "are tall and especially strong, their skin is not very white, and their hair is neither blond nor black, but all have reddish hair. They are neither dishonourable nor spiteful, but simple in their ways, like the Huns (Avars)". "Some of them do not have either a tunic or cloak, but only wear a kind of breeches pulled up to the groin."
Anthropological investigation of prehistoric Slavic sites appears to support the historical literature, suggesting that the early Slavs were dolicocephalic and fair-haired. However, Biological anthropology (especially the cranial index) has been devalued. According to Luigi Luca Cavalli-Sforza, anthropological observations are as likely to reflect socio-economic, nutritional or environmental factors as genetic differences. Although modern Slavs have a variety of genetic backgrounds, haplogroup R1a (Y-DNA) predominates: 63.39 percent in the Sorbs, 56.4 percent in Poland, 54 percent in Ukraine, 47 percent in Russia, 39 percent in Belarus, 24.6 percent in Bosnia, 15.2 percent in Macedonia, 14.7 percent in Bulgaria and 12.1 percent in Herzegovina.
Early Slavic society was a typical, decentralized tribal society of Iron Age Europe, organised into local chiefdoms. A slow consolidation occurred between the seventh and ninth centuries. During this period, the previously-uniform Slavic cultural area evolved into discrete zones. Slavic groups were influenced by neighbouring cultures like Byzantium, the Khazars, the Vikings and the Carolingians, influencing their neighbours in return.
Differences in status gradually developed in the chiefdoms, leading to the development of centralized socio-political organizations. The first centralized organizations may have been temporary pan-tribal warrior associations. The greatest evidence for this is in the Danubian area, where barbarian groups organized around military chiefs to raid Byzantine territory and defend themselves against the Pannonian Avars. Social stratification gradually developed in the form of fortified, hereditary chiefdoms, first seen in the West Slavs areas. The chief was supported by a retinue of warriors who owed their position to him. As chiefdoms became powerful and expanded, centres of subsidiary power ruled by lesser chiefs were created; the line between powerful chiefdoms and centralized medieval states is blurred. By the mid-ninth century, the Slavic elite was sophisticated. They wore luxurious clothing, rode horses, hunted with falcons and travelled with retinues of soldiers.
Early Slavic settlements were no larger than .5 to 2 hectares (1.2 to 4.9 acres). Settlements were often temporary, perhaps reflecting their itinerant form of agriculture, and were often along rivers. They were characterized by sunken buildings, known as Grubenhäuser in German or poluzemlianki in Russian. Built over a rectangular pit, they varied from 4 to 20 square metres (43 to 215 sq ft) in area and could accommodate a typical nuclear family. Each house had a stone or clay oven in a corner (a defining feature of Eastern European dwellings), and a settlement had a population of fifty to seventy. Settlements had a central, open area, where communal activities and ceremonies were conducted, and were divided into production and settlement zones.
Strongholds appeared during the ninth century, especially the Western Slavic territories, and were often found in the centre of a group of settlements. The South Slavs did not form enclosed strongholds; they lived in open, rural settlements adopted from the social models of the indigenous populations they encountered.
Tribal and territorial organization
Settlements were not uniformly distributed; they are found in clusters, separated by areas of lower settlement density. The clusters resulted from the expansion of single settlements, and these "settlement cells" were linked by familial or clan relationships. Settlement cells were the basis of the simplest form of territorial organization, known as a župa in South Slavic and opole in Polish. According to the Primary Chronicle, "The men of the Polanie lived each with his own clan in his own place". Several župas, encompassing individual clan territories, formed the known tribes: "The complex processes initiated by the Slav expansion and subsequent demographic and ethnic consolidation culminated in the formation of tribal groups, which later coalesced to create state which form the framework of the ethnic make-up of modern eastern Europe".
The root of many tribal names denotes the territory which they inhabited, such as the Milczanie (who lived in areas with měl - loess), Moravians (along the Morava), Diokletians (near the former Roman city of Doclea) and Severiani (northerners). Other names have more general meanings, such as the Polanes(pola; field) and Drevlyans (drevo; tree). Others appear to have a non-Slavic (possibly Iranian) root, such as the Antes, Serbs and Croats. Some geographically-distant tribes appear to share names. The Dregoviti appear north of the Pripyat River and in the Vardar valley, the Croats in Galicia and northern Dalmatia and the Obodrites near Lübeck and their further south in Pannonia. Four groups retained the root Slav in their names: the Slovenes, Slovaks, Slavonians and the historical east-Slavic Slovens. There is little evidence of migratory links between tribes sharing the same name. The common names may reflect names given the tribes by historians or a common tongue as a distinction between Slavs (slovo; word, letter) and others; Nemci (mutes) is a Slavic name for "Germans". In 1998, Walter Pohl wrote:
Apparently ethnicity operated on at least two levels: the "common Slavic" identity, and the identity of single Slavic groups, tribes, or peoples of different sizes that gradually developed, very often taking their name from the territory they lived in. These regional ethnogeneses inspired by Slavic tradition incorporated considerable remnants of Roman and Germanic population ready enough to give up ethnic identities that had lost their cohesion.
The first historical Slavic state was founded by Samo during the seventh century. Located in present-day Bohemia, Moravia, Slovakia, Germany, Austria and Slovenia, it became Great Moravia and Carantania. The Duchy of Pannonia, Duchy of Dalmatia and Bulgaria emerged in the Balkans. In the north, the first states were founded by the Obodrites and Wieletes.
Early barbarian warrior bands, typically numbering two hundred or less, were intended for fast penetration into enemy territory and an equally-quick withdrawal. In Wars VII.14, 25, Procopius wrote that the Slavs "fight on foot, advancing on the enemy; in their hands they carry small shields and spears, but they never wear body armour". According to the Strategikon, the Slavs favoured ambush and guerrilla tactics and often attacked their enemy's flank: "They are armed with short spears; each man carries two, one of them with a large shield". Sources also mention the use of cavalry. Theophylact Simocatta wrote that the Slavs "dismounted from their horses in order to cool themselves" during a raid, and Procopius wrote that Slav and "Hun" horsemen were Byzantine mercenaries. In their dealings with Sarmatians and Huns the Slavs may have become skilled horsemen, explaining their expansion. According to the Strategikon (XI.4.I-45), the Slavs were a hospitable people who did not keep prisoners indefinitely "but lay down a certain period after which they can decide for themselves if they want to return to their former homelands after paying a ransom, or to stay amongst the Slavs as free men and friends".
Little is known about Slavic religion before the Christianization of Kievan Rus’; After Christianization, Slavic authorities destroyed many records of the old religion. Some evidence remains in apocryphal and devotional texts, the etymology of Slavic religious terms and the Primary Chronicle.
Early Slavic religion was relatively uniform: animistic, anthropomorphic and inspired by nature. The Slavs developed cults around natural objects, such as springs, trees or stones, out of respect for the spirit (or demon) within. Slavic pre-Christian religion was originally polytheistic, with no organized pantheon. Although the earliest Slavs seemed to have a weak concept of God, the concept evolved into a form of monotheism where a "supreme god [ruled] in heaven over the others". There is no evidence of a belief in fate or predestination.
Pre-Christian Slavic spirits and demons could be entities in their own right or spirits of the dead, associated with home or nature. Forest spirits, entities in their own right, were venerated as the counterparts of home spirits (usually related to ancestors). Demons and spirits were good or evil, suggesting that the Slavs had a dualistic cosmology, and were revered with sacrifices and gifts.
Slavic pre-Christianity was syncretistic, combined and shared with other religions (including Germanic paganism). Linguistic evidence indicates that part of Slavic pre-Christianity developed when the Balts and Slavs shared a common language; pre-Christian Slavic beliefs contained elements also found in Baltic religions. After the Slavic and Baltic languages diverged, the early Slavs interacted with Iranian peoples and incorporated elements of Iranian spirituality. Early Iranian and Slavic supreme gods were considered givers of wealth, unlike the supreme thunder gods of other European religions. Slavs and Iranians had demons, with names from similar linguistic roots (Iranian Daêva and Slavic Divŭ) and a concept of dualism: good and evil.
Although evidence of pre-Christian Slavic worship is scarce (suggesting that Slavic pre-Christianity was aniconic), religious sites and idols are most plentiful in Ukraine and Poland. Slavic temples and indoor places of worship are rare; outdoor places of worship are more common, especially in Kievan Rus'. These outdoor cultic sites were often on hills and included ringed ditches. Indoor shrines existed: "Early Russian sources ... refer to pagan shrines or altars known as kapishcha;" these were small, enclosed structures with an altar inside. One was found in Kiev, surrounded by the bones of sacrificed animals. Pagan temples were documented as destroyed during Christianization.
Records of pre-Christian Slavic priests, like the pagan temples, appeared later. Although no early evidence of Slavic pre-Christian priests has been found, the prevalence of sorcerers and magicians after Christianization suggests that the pre-Christian Slavs had religious leaders. Slavic pagan priests were believed to commune with the gods, predict the future and prepare for religious rituals. The pagan priests, or magicians (known as volkhvy by the Rus' people), resisted Christianity after Christianization. The Primary Chronicle describes a campaign against Christianity in 1071, during a famine. The volkhvy were well-received nearly 100 years after Christianization, suggesting that pagan priests had an esteemed position in 1071 and in pre-Christian times.
Although the Slavic funeral pyre was seen as a means of freeing the soul from the body in a rapid, visible and public manner,[not in citation given] archaeological evidence suggests that the South Slavs quickly adopted the burial practices of their post-Roman Balkan neighbours.
Christianization began in the ninth century, and was not complete until the second half of the twelfth. The Christianization of Bulgaria resulted from Boris I's shifting political alliances with the kingdom of the East Franks and the Byzantine Empire and his reception by the Pope. Because of Bulgaria's strategic position, the Greek East and the Latin West wanted its people to adhere to their liturgies and ally with them politically. After overtures from each side, Boris aligned with Constantinople. Through Byzantium, he secured an autocephalous Bulgarian national church.
Although there is some evidence of early Christianization of the East Slavs, Kievan Rus' remained largely pagan (or relapsed into paganism) before the baptism of Vladimir the Great in the 980s. The Christianization of Poland began with the baptism of Mieszko I in 966. Slavic paganism persisted into the 12th century in Pomerania, which began to be Christianized after the creation of the Duchy of Pomerania as part of the Holy Roman Empire in 1121; the process was mostly completed with the Wendish Crusade of 1147. The final stronghold of Slavic paganism were the Rani, with a temple to their god Svetovid on Cape Arkona which was taken in a campaign by Valdemar I of Denmark in 1168.
After Christianisation, the Slavs established a number of kingdoms (or feudal principalities) which persisted through the High Middle Ages. After the 1054 death of Yaroslav the Wise, the East Slavs fragmented into a number of principalities from which Muscovy would emerge after 1300 as the most powerful. The western principalities of the former Kievan Rus' became parts of the Grand Duchy of Lithuania.
The South Slavs consolidated the Grand Principality of Serbia and the Bulgarian Empire. The Kingdom of Croatia, in the Balkans, was composed of present-day Croatia (without most of Istria and some Dalmatian coastal cities) and parts of modern-day Bosnia and Herzegovina. The West Slavs were distributed among Poland, the Kingdom of Hungary (Slovakia) and the Holy Roman Empire (Bohemia and Moravia).
The debate between proponents of autochthonism and allochthonism began in 1745, when Johann Christoph de Jordan published De Originibus Slavicis. The 19th-century Slovak philologist and poet Pavel Jozef Šafárik, whose theory was founded on Jordanes' Getica, has influenced generations of scholars. Jordanes equated the Sclavenes, the Antes and the Venethi (or Venedi), based on earlier sources such as Pliny the Elder, Tacitus and Ptolemy. Šafárik's legacy was his vision of a Slavic history and the use of linguistics for its study. Polish scholar Tadeusz Wojciechowski (1839–1919) was the first to use place names in the study of Slavic history, followed by A. L. Pogodin and botanist J. Rostafinski.
The first scholar to introduce archaeological data into the discourse about the early Slavs, Lubor Niederle (1865–1944), endorsed Rostafinski's theory in his multi-volume Antiquities of the Slavs. Vykentyi V. Khvoika (1850–1914), a Ukrainian archaeologist of Czech origin, linked the Slavs with the Neolithic Cucuteni culture. A. A. Spicyn (1858–1931) attributed finds of silver and bronze in central and southern Ukraine to the Antes. Czech archaeologist Ivan Borkovsky (1897–1976) postulated the existence of a Slavic "Prague type" of pottery. Boris Rybakov has linked Spicyn's "Antian antiquities" with Chernyakhov-culture remains excavated by Khvoika, theorizing that the former should be attributed to the Slavs. The debate became politically charged during the 19th century (particularly in connection with the partitions of Poland and the German Drang nach Osten), and the question of whether Germanic or Slavic peoples were indigenous east of the Oder was used to pursue German and Polish claims to the region.
