Inthe vast grasslands of the Steppes, south of the Ural mountains in present-day Russia-Kazakhstan border, archaeologists, in the 1970s, discovered over twenty settlements dated 2100 BC to 1800 BC. They named the culture after Sintashta, a circular fortified town roughly 140 m in diameter.
This obscure culture, seldom mentioned in history books, transformed human mobility for the next four thousand years.
The people of Sintashta built chariots and bred the modern horse. The horses were so desirable they replaced every horse breed in the world.
