Balts
The Balts or Baltic people is an Indo-European ethnic-linguistic group that speaks Baltic languages, a branch of the Indo-European language family, which was originally spoken by tribes living in the area of Jutland peninsula in the west and Moscow, Oka and Volga rivers basins in the east. One of the features of Baltic languages is the number of conservative or archaic features retained. Among the Baltic peoples are modern Lithuanians, Latvians (including Latgalians) — all Eastern Balts — as well as the Prussians, Yotvingians and Galindians — the Western Balts — whose languages and cultures are now extinct.
