I do not deny the existance of slavic tribes, but slavic is not a tribe its a linguistic group, like germanic. . sycthians , sarmatians are not slavic tribes........I would like to know who are these slavic tribes by name.
Only 1 tribe is said to be slavic, a tribe called Stavani (Stavanoi) who lived in the northern Carpathian mountains.
You cannot claim anything due to language, if this is incorrect, then you are english because we communicate in english.
Baltic prusians, would be some, poles, latvians, estonians etc etc dispersed....there are even genetic markers for them.
I think you can guess,
from all Roman and Greek chronicles we don't know them,
they could be here, or they could came from elsewhere,
but the first seems little bit stretchedto be such a big linguistic group and no Historian mention about,
so they came from else where,
possible areas, North far North, East inland (very north from Crimea or more East)
by watching the dates we see that Goths Vandals are leaving central Europe after ROMAN dicline, we see Huns and other steppe people to arive, also we see the Northern exit to Black sea of Varragians,
from History we know that Thracians and especially a quenn named Tomaris comes from Caspian sea,
meaning that Thracian were till Caspian,
also we know that Scythians entered and created Scythia minor, so Scythian and Thracian got mixed already,
from the Golden Horde and the rest steppe Hordes we see only Magyar and Finn kept their language,
so in one hand we have a possible known nation or group of tribes, and the on the other an unknown,
but we know Slavic although were recorded in Great moravia, were spoken even to Roxolani lands,
that again leads us to 2 lands of origin,
1 is the North and central Europe, and Varangians to East to spread them, and the other is lands near Roxolani,
But
conserning Balkans we have 2 entries, one is the known from Great Moravia and Pannonia , and the other is the Severi from Ucraine via Romania,
the second is a key,
Bulgars of Asparuch were allies of Severi, they settled side by side and they cooperate, they almost moved same time through roads that are beside, when enter Balkans,
if we understand that then we have a key. that leads us beside to Scythia major, or even scythia major it shelve, while through Scythian minor they were already familiar with Thracian,
also the case of Sclavini
their entrance in Great Moravia and Balkans seems to be the spark of the rest known world to face them with different eye,
Sparkey in a Thread said that it si very possible that some Y HG in Balkans came from Central Europe and Ucraine,
it is clear that Slavic languages were mainly developed outside Roman empire, (the inside but from paysants and peacefull people, seems not ok with me)
from a population that was forced to devastate or cooperate with Steppe people invasion from East, and not from North, but from Linguistic we know that are relative with Baltic,
that means either that both came-enter almost same or near time-age, or the one was near the other,
so the solutions are
Baltic came same time with Slavic?
Baltic was spoken in Baltic lands before, so Slavic language was a nearby area language.
no matter what seems like their exodus to central and south Europe was done as a chain reaction with Roman decline, Goths, Huns etc to a relative speaking population, Scytho-Thracians
