Oktai was one of Chengis Khan's four sons by his first wife and the first to rule the empire after Chengis Khan's death.

The Mongols at that time were 300 years ahead of the rest of the world in military science. There was no possibility of any European army defeating the Golden Horde (the large army which Batui and Subudai had brought across the Volga in 1236) or of halting any serious move it might have made.

Yup. I thought Ghengis split the empire among his four sons.
