Genghis Khan was the emperor of the Mongolian empire and his name means universal ruler. Temujin was Genghis Khans birth name and name when he was younger. Genghis khan gained lots of people that thought that he should be emperor and eventually when he was 18 he ruled over the Mongolians. His brother made a code of law called the Yassa and the empire had to follow these rules or be severely punished or tortured. Genghis’s army was a strong and bold army and captured and won lots of battles. Mongols today still worship him because of his braveness and boldness of the smart ruler.
