Kurgan Hypothesis - Overview

Overview

When it was first proposed in 1956, in The Prehistory of Eastern Europe, Part 1, Marija Gimbutas's contribution to the search for Indo-European origins was a pioneering interdisciplinary synthesis of archaeology and linguistics. The Kurgan model of Indo-European origins identifies the Pontic-Caspian steppe as the Proto-Indo-European (PIE) Urheimat, and a variety of late PIE dialects are assumed to have been spoken across the region. According to this model, the Kurgan culture gradually expanded until it encompassed the entire Pontic-Caspian steppe, Kurgan IV being identified with the Pit Grave culture of around 3000 BC.

The mobility of the Kurgan culture facilitated its expansion over the entire Pit Grave region, and is attributed to the domestication of the horse and later the use of early chariots. The first strong archaeological evidence for the domestication of the horse comes from the Sredny Stog culture north of the Azov Sea in Ukraine, and would correspond to an early PIE or pre-PIE nucleus of the 5th millennium BC.

Subsequent expansion beyond the steppes led to hybrid, or in Gimbutas's terms "kurganized" cultures, such as the Globular Amphora culture to the west. From these kurganized cultures came the immigration of proto-Greeks to the Balkans and the nomadic Indo-Iranian cultures to the east around 2500 BC.
