Characteristic of Sintashta culture

The Sintashta culture, also known as the Sintashta-Petrovka culture or Sintashta-Arkaim culture, is a Bronze Age archaeological culture of the northern Eurasian steppe on the borders of Eastern Europe and Central Asia, dated to the period 2100–1800 BCE. The culture is named after the Sintashta archaeological site, in Chelyabinsk Oblast, Russia.
The Sintashta culture is widely regarded as the origin of the Indo-Iranian languages. 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.
