When did Baltic peoples arrive in the eastern Baltic region?

The ancestors of the Baltic peoples arrived in the vast region of the eastern Baltic and west-central Russia during the 3rd millennium BCE. Upon their arrival, they brought with them established knowledge of agriculture and cattle raising.1

While the precise prehistoric origins of the Balts remain obscure, linguistic evidence suggests that the ancestors of the Balts moved from the south and settled across a large area of the eastern coast of the Baltic Sea and the upper reaches of the Dnieper River, likely breaking off from earlier close contact with Germanic tribes around the 2nd millennium BCE.12
