How is the history of the Eastern Slavs connected with the great migration of peoples?

The great migration of peoples, which began in the IV century with the invasion of the Eastern Europe by the Huns, had a great influence on the formation of the Slavic ethnos.
After the processes of the Great Nations Migration, the Slavs formed three stable territorial groups: South, West and East Slavs. During this period, the Slavs settled beyond the Elbe, on the territory of Byzantium and on the shores of the Baltic Sea.
The East Slavic Antsk state fell under the blows of the Turkic peoples.
The process of resettlement at the same time contributed to the consolidation of the Eastern Slavs, whose center of settlement was the Middle Dnieper region. Over time, Kiev was founded here. peoples came and disappeared, and for the Eastern Slavs were the autochthons of these territories, on which over time, in the 9th century, the East Slavic state was formed.
