The correct answer is the Golden Horde.
It was a Mongol state that was located in present-day Russia, Ukraine and Kazakhstan in 1240. The horde of gold was created after Genghis Khan decided to divide the Mongol empire into 4 states and governed each of his sons.
The Golden Horde dominated until the end of the 15th century the south of present-day Russia.
