Modu Chanyu (Maodun, Maotun, Mode; sometimes also transcribed Modun and Maodun), born c. 234 BCE, is the fourth known emperor and founder of the Xiongnu Empire after he kills his father in 209 BCE.
The years of his rule are 209 BCE to 174 BCE.
He is a military leader under his father Touman, and later the Chanyu and king of the Xiongnu, centered in modern day Mongolia.
Once he secures the throne, he establishes a powerful Xiongnu Empire by successfully unifying the tribes of the Mongolian steppes and hence poses an imminent threat to the Chinese Qin Dynasty.
His Xiongnu Empire is one of the largest of his time – the eastern border stretches as far as the Liao River, the western borders of the empire reached the Pamir Mountains while the northern border reaches Lake Baikal.
