in the 5th and 6th centuries. From the Danube, the Slavs commenced raiding the Byzantine Empire on an annual basis from the 520s, spreading destruction, taking loot and herds of cattle, seizing prisoners and taking fortresses. Often, the Byzantine Empire was stretched, defending its rich Asian provinces from Arabs, Persians and others. This meant that even numerically small, disorganised early Slavic raids were capable of causing much disruption, but could not capture the larger, fortified cities. The first Slavic raid south of the Danube was recorded by Procopius, who mentions an attack of the Antes, "who dwell close to the Sclaveni", probably in 518. Sclaveni are first mentioned in the context of the military policy on the Danube frontier of Byzantine Emperor

arrived at the Black Sea steppe, and defeated the Antes between the Dnieper and Dniester. The Avars subsequently allied themselves with the Sclaveni, although there was an episode in which the Sclavene
Daurentius (fl. 577–579), the first Slavic chieftain recorded by name, dismissed Avar suzerainty and retorted that "Others do not conquer our land, we conquer theirs
..so it shall always be for us", and had the Avar envoys slain. By the 580s, as the Slav communities on the Danube became larger and more organized, and as the Avars exerted their influence, raids became larger and resulted in permanent settlement. Most scholars consider the period of 581–584 as the beginning of large-scale Slavic settlement in the Balkans. F.

, after which religious allegiance was to Rome. Croats threw off Frankish rule in the 9th century and took over the Byzantine Dalmatian towns, after which Hungarian conquest led to Hungarian suzerainty, although retaining an army and institutions. Croatia lost much of Dalmatia to the Republic of Venice which held it until the 18th century. Hungary governed Croatia through a duke, and the coastal towns through a ''
ban''. A feudal class emerged in the Croatian hinterland in the late 13th century, among whom were the
Kurjaković,
Kačić and most notably the
Šubić. Dalmatian fortified towns meanwhile maintained autonomy, with a Roman patrician class and Slavic lower class, first under Hungary and then Venice after centuries of struggle.
Ibn al-Faqih described two kinds of South Slavic people, the first of swarthy complexion and dark hair, living near the Adriatic coast, and the other as light, living in the hinterland.

The Serbo-Croatian varieties have strong structural unity and are regarded by most linguists as constituting one language. Today, Language secessionism#In Serbo-Croatian, language secessionism has led to the codification of several distinct standards: Serbian, Croatian, Bosnian and Montenegrin. These Serbo-Croatian standards are all based on the Shtokavian dialect group. Other dialect groups, which have lower intelligibility with Shtokavian, are Chakavian in Dalmatia and Kajkavian in Croatia proper. The dominance of Shtokavian across Serbo-Croatian speaking lands is due to historical westward migration during the Ottoman period. Slovene is South Slavic but has many features shared with West Slavic languages. The Prekmurje Slovene and Kajkavian are especially close, and there is no sharp delineation between them. In southeastern Serbia, dialects enter a transitional zone with Bulgarian and Macedonian, with features of both groups, and are commonly called Torlakian. The Eastern South Slavic languages are Bulgarian and Macedonian. Bulgarian has retained more archaic Slavic features in relation to the other languages. Bulgarian has two main yat splits. Slavic Macedonian was codified in Communist Yugoslavia in 1945 and was historically classified as Bulgarian. The Macedonian dialects, divided into three main groups, are regarded overall as being transitional to Bulgarian and Serbo-Croatian. The westernmost Bulgarian dialects (called Shopi) share features with Serbo-Croatian. Furthermore, in Greece there is a notable Slavic-speaking population Slavic speakers of Greek Macedonia, in Greek Macedonia and Pomaks, western Thrace. Balkan Slavic languages are part of a "Balkan sprachbund" with areal features shared with other non-Slavic languages in the Balkans.
Genetics

According to the 2013 Autosome, autosomal Identity by descent, IBD survey "of recent genealogical ancestry over the past 3,000 years at a continental scale", the speakers of Serbo-Croatian language share a very high number of common ancestors dated to the migration period approximately 1,500 years ago with Poland and Romania-Bulgaria cluster among others in Eastern Europe. It is concluded to be caused by the Huns, Hunnic and Slavic expansion, which was a "relatively small population that expanded over a large geographic area", particularly "the expansion of the Slavic populations into regions of low population density beginning in the sixth century" and that it is "highly coincident with the modern distribution of Slavic languages".
According to Kushniarevich et al. 2015, the Hellenthal et al. 2014 IBD analysis also found "multi-directional admixture events among East Europeans (both Slavic and non-Slavic), dated to around 1,000–1,600 YBP" which coincides with "the proposed time-frame for the Slavic expansion".
The Slavic influence is "dated to 500-900 CE or a bit later with over 40-50% among Bulgarians, Romanians, and Hungarians".
The 2015 IBD analysis found that the South Slavs have lower proximity to Greeks than with East and West Slavs and that there's an "even patterns of IBD sharing among East-West Slavs–'inter-Slavic' populations (Hungarians,

and Gagauz people, Gagauz)–and South Slavs, i.e. across an area of assumed historic movements of people including Slavs". The slight peak of shared IBD segments between South and East-West Slavs suggests a shared "Slavonic-time ancestry".
The 2014 IBD analysis comparison of Western Balkan and Middle Eastern populations also found negligible gene flow between 16th and 19th century during the Islamization of the Balkans.
According to a 2014 Genetic admixture, admixture analysis of Western Balkan, the South Slavs show a genetic uniformity. The Bosnians and Croatians were more close to East European populations and largely overlapped with Hungarians from Central Europe.
In the 2015 analysis, they formed a western South Slavic cluster with the Bosnians and Slovenians in comparison to eastern cluster formed by Macedonians and Bulgarians with Serbians in the middle. The western cluster has an inclination toward Hungarians, Czechs, and Slovaks, while the eastern cluster toward Romanians and some extent Greeks.
The modeled ancestral genetic component of Balto-Slavs among South Slavs was between 55-70%.
In the 2018 analysis of Slovenian population, the Slovenian population clustered with Croatians, Hungarians and was close to Czech.
The 2006 Y-DNA study results "suggest that the Slavic expansion started from the territory of present-day Ukraine, thus supporting the hypothesis that places the earliest known homeland of Slavs in the basin of the middle

According to genetic studies until 2020, the distribution, variance and frequency of the Human Y-chromosome DNA haplogroup, Y-DNA haplogroups Haplogroup R1a, R1a and Haplogroup I-M438#I2a-L621, I2 and their subclades R-M558, R-M458 and I-CTS10228 among South Slavs are in correlation with the spreading of Slavic languages during the medieval Slavic expansion from Eastern Europe, most probably from the territory of present day Ukraine and Lesser Poland, Southeastern Poland.
