Hypothetical Prehistoric Migrations

"Period Migrations - Early Eneolithic" (A Storm of Hordes)

Chalcolithic Europe, the Chalcolithic (also Aeneolithic, Copper Age) period of Prehistoric Europe, lasted roughly from 3500 to 1700 BCE.

It was a period of Megalithic culture, the appearance of the first significant economic stratification, and probably the earliest presence of Indo-European speakers.

The economy of the Chalcolithic, even in the regions where copper was not yet used, was no longer that of peasant communities and tribes: some materials began to be produced in specific locations and distributed to wide regions. Mining of metal and stone was particularly developed in some areas, along with the processing of those materials into valuable goods.

Earlier, from c. 5000 BC to 3000 BCE, use of copper began in the Balkans, Eastern Europe, and Central Europe. From c. 3500 onwards, there was an influx of people into Eastern Europe from the area east of the Volga (Yamnaya culture), creating a plural complex known as Sredny Stog culture. This culture replaced the Dnieper-Donets culture, and migrated towards the Northwest to the Baltic and Denmark, where they mixed with natives (TRBK A and C). This may be correlated with the linguistic fact of the spread of Indo-European languages; see Kurgan hypothesis. Near the end of the period, another branch would leave many traces in the lower Danube area (culture of Cernavodă culture I), in what seems to be another invasion.
