The history of the development of the eastern European plain.

The first inhabitants who settled in this area were Cro-Magnons. This process took place
about thirty thousand years ago.
Closer to the tenth millennium BC, the first Indo-Europeans began to appear here, who had previously lived in the southern part of Europe.
The settlement and development of lands by Eastern Europeans began actively in the fifth-seventh century AD.
And by the eighth century, their numbers became dominant, and under their leadership the first tribal
unions, the emergence of statehood began.
