Corded Ware culture
The Corded Ware culture in Middle Europe (c. 3200 or 2,900–2450 or 2350 cal. BCE) probably played an essential role in the origin and spread of the Indo-European languages in Europe during the Copper and Bronze Ages. David Anthony states that "Childe (1953:133-38) and Gimbutas (1963) speculated that migrants from the steppe Yamnaya horizon (3300–2600 BCE) might have been the creators of the Corded Ware culture and carried IE languages into Europe from the steppes."
