The Sintashta culture is a Middle Bronze Age archaeological culture of the Southern Urals, dated to the period c. 2200–1900 BCE. It is the first phase of the Sintashta–Petrovka complex, c. 2200–1750 BCE. The culture is named after the Sintashta archaeological site, in Chelyabinsk Oblast, Russia, and spreads through Orenburg Oblast, Bashkortostan, and Northern Kazakhstan. The Sintashta culture is thought to represent an eastward migration of peoples from the Corded Ware culture. It is widely regarded as the origin of the Indo-Iranian languages, whose speakers originally referred to themselves as the Arya. The earliest known chariots have been found in Sintashta burials, and the culture is considered a strong candidate for the origin of the technology, which spread throughout the Old World and played an important role in ancient warfare. Sintashta settlements are also remarkable for the intensity of copper mining and bronze metallurgy carried out there, which is unusual for a steppe culture. Among the main features of the Sintashta culture are high levels of militarism and extensive fortified settlements, of which 23 are known.

The Corded Ware culture comprises a broad archaeological horizon of Europe between c. 3000 BC – 2350 BC, thus from the late Neolithic, through the Copper Age, and ending in the early Bronze Age. Corded Ware culture encompassed a vast area, from the contact zone between the Yamnaya culture and the Corded Ware culture in south Central Europe, to the Rhine in the west and the Volga in the east, occupying parts of Northern Europe, Central Europe and Eastern Europe. Early autosomal genetic studies suggested that the Corded Ware culture originated from the westward migration of Yamnaya-related people from the steppe-forest zone into the territory of late Neolithic European cultures; however, paternal DNA evidence fails to support this hypothesis, and it is now proposed that the Corded Ware culture evolved in parallel with the Yamnaya, with no evidence of direct male-line descent between them.
