Around 1205 A.D., a tribal leader emerged in Mongolia that would change the fate of the people for centuries. This man’s name was Temujin.
Temujin worked to unite the many different tribes in Mongolia under a single government. After successfully bringing the Mongolians together, he established written laws known as the yasa. The yasa guided the actions of Mongolians throughout the whole of their empire.
Temujin also established a powerful military, and insured that they had the best weaponry and training of any army on Earth at the time. As a result of his successes, his people began to refer to Temujin as the Khan, or king. He became known as the Genghis Khan.
