Baltic is a member of the Satem division, closest to Slavic, and is at the same time the most archaic surviving form of Indo-European speech.
It is not known when the ancestors of the Balticpeoples left this primeval home and moved northwestward to their present habitat, but the bulk of the migration probably did not antedate the beginning of the Iron Age.
The independence of the Balticpeoples was destroyed in 1561, when Esthonia went to Sweden, and Latvia and Lithuania were handed back and forth between Russia, Poland, and Sweden; at the time of the final partitionment of Poland they went to Russia.
Among the Balticpeoples are modern Lithuanians Lithuanians are a Baltic ethnic group, associated with Lithuania and the Lithuanian language.
The Baltic occupation of Western Russia Galindae, Galindai, or Galindians is an extinct Western Baltictribe which formerly lived in Galindia: in Masuria, Poland (so-called Western Galindae) and in the basin of the Protva River, near the modern Russian towns of Mozhaysk, Vereya, and Borovsk (so-called Eastern Galindae).
The Baltic culture that remained in the Dneper area, although bore significant resemblance to its Baltic counterpart, was also similar to culture of other peoples inhabitating the forests of Eastern Europe and became almost completely Slavicised between 7th and 10th centuries.
