Eastern European cultures of the beginning of the 2nd millennium BC, first of all, Babino and Abashevo, to a lesser extent Lola and Sintashta, have some Central European inclusions, indicating migration from west to east during this period. This makes it possible to establish chronological relations of the complexes of Eastern Europe, the Urals and Kazakhstan at the transition from the Eurasian Middle to Late Bronze Age with the Central European Early Bronze Age2 complexes. Most of the parallels between these regions are dated within broad chronological frameworks. However, comparison of the whole complex of common features allows determining the initial date of the discussed Eastern cultures within phase A1c of Central Europe, which is in a good agreement with radiocarbon dates. Analysis of these materials shows that components formed on the post-Bell-Beaker and post-Corded basis penetrated into Eastern Europe. At the same time, there was a flow from the south, and it is possible that it reached Central Europe.
