How I2a2 came to Balkans
“At the time of Attila the Hun a portion of Alans living in the "Sarmatia of the Cimmerian Bosporus" moved northwest into the land of Venedes (according to M.A. Sabellico, J.A. de Thouand some others historians[22]), possibly merging with Western Balts there to become the precursors of historic Slav nations.”

I strongly believe this is how it was. There are several articles which cover this issue and with some effort it is not hard to conclude that this version of events is correct and actually confirmed by genetics data. What was a historical assumption, that origin of South Slavs is somehow different has now found even stronger foundation in genetics.
For me personally this issue is finished. I’m just going to shortly repeat what is already written in different sources. I’m just a bit surprised no one earlier connected Sarmatians and I2a2.
- There are sources which place Sarmatians in Sarmatia Asiatica even 1200 BC
- They spoke a language which belongs to Iranian group of languages
- Around 300 BC Sarmatians conquered western Scythians and their land was from Carpathians to Caspian Sea
- In 3rd century AC Goths (Thervingi and Greuthungi) established their ascendancy northwest of Black Sea and divided Sarmatians to western (Antes, Taifals and others) and eastern, that is Alans which included Croats and Serbs.
- In 370 AC Huns won their first war and it was against Alans. Some Alans were killed, some retreated and finished somewhere in western Europe, and some became major allies of Huns. These allies included Serbs and Croats.
- It is crucial to understand that Huns turned half of the Europe upside down and before and after them nothing was the same.
- Huns had a role for Alans and other Sarmatians that they conquered later (Antes and others) and it was to put under control Venedes (Slavs). Sarmatians were placed along south boundaries of Slavic tribes territory (Czech republic, south Poland and western Ukraine) and governed some of their territories to the north.
- In 5th century Alans (including, Serbs, Croats), Antes started speaking Slavic language.
- After Hunnic Empire had fall, it is unknown to me did Sarmatians preserve their domination over Slavic tribes, but it is clear that they did not significantly change their geographical position. First migrations may have been towards Wallachian Plain by tribes close to Antes.
- In 7th century these Slavic speaking Sarmatian descendents settled all over Balkans including emptied territories in western Balkans. Areas in western Balkans were abandoned because of Avar invasions and because Byzantine Emperor Heraclius wanted Serbs and Croats to settle there.
- The difference in I2a2 haplotypes (Dinaric South and Dinaric North) can be explained with assumption that Dinaric South descends from Alans and Dinaric North from western Sarmatians (including Antes).
I apologize to all forum members, but I’m not sure how available I will be to answer possible questions. Anyway please try to find the data by yourself. You will believe it more that way.
