The Mongols and Yuan Dynasty
The Mongols were divided into clans and ruled by khans. The khans became khans by accelerating in their military skills and ability to lead. The most powerful khan was Temujin, who earned the name Genghis Kahn, which meant, "Universal leader". He wanted to build an empire. He was a cunning military leader and had great battle tactics. While the Mongol empire sounds like a brutal place, they actually ruled it peacefully.
