History

The Slavs who settled in the Balkans are divided into two groups,

, culminating with the Siege of Constantinople (626). According to Procopius, Slavic social and political organization was a kind of ''demokratia'' in which the tribal community was ruled by the council of nobles. This allowed them to stay together regardless of environmental factors, but according to Johannes Koder, "impeded coordinated military resistance against the enemy", which put them in a situation of being under foreign political leadership. When the Slavs and later the Avars entered the Balkans they didn't have advanced siege warfare, but around 587 they acquired this knowledge from contact with Byzantine culture, and because of this no urban settlement or fort could oppose them any more. With the destruction of Roman fortifications came a loss of Byzantine military and administrative power in Roman provinces. The native population was often decimated, and the devastated lands were resettled by smaller or larger groups of Slavs. Settlement among the natives, often replacing them, happened in the autumn, when winter supplies were secured for the people and animals. After mixing with the natives who survived in smaller communities, depending on the region, the Slavic tribes mostly had names of

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 slight peak of shared IBD segments between South and East-West Slavs suggests a shared "Slavonic-time ancestry". According to a recent admixture analysis of Western Balkan, the South Slavs show a genetic uniformity, with the modeled ancestral genetic component of Balto-Slavs among South Slavs being between 55% and 70%. According to 2017 admixture study of Peloponnesian Greek population, "the Slavic ancestry of Peloponnesean subpopulations ranges from 0.2 to 14.4%".

Among present-day populations "Greeks and Albanians have more Anatolian Neolithic ancestry than their South Slavic neighbors".
