Dae Jo-yeong (died 719), also known in Korea as King Go, establishes the state of Balhae, reigning from 699 to 719.

His origin is heavily claimed by Chinese historians as of Mohe tribe decent.

However it is proven that he is of Goguryeo royal decent.

Since royal families in both China and Korea at this time have many members, different last names sre distributed so that hundreds of people are not directly recognized as heirs to the throne or a part of the "Go" royal family name.

Go and Dae, both meaning high and great in definition, signifies Dae Jo Young's last name to be one of the branches of the "Go" family line.
