Dae Jung-Sang

Tae Chungsang, also known as Kŏlgŏl Chungsang, was a key contributor to the founding of Balhae, and the father of Tae Choyŏng, the actual founder of Balhae. Though much of the credit for the founding of Balhae went to his son, many historians still give credit to Tae Chungsang as the main supporter and leader in the founding of Balhae.
