The Birth and Social Status of Chang Po-go

There are a few remains on Chang Po-go's birth. In a book called 'Fan Chuan Wen Ji' in Chinese(Beon-Cheon-Moon-Jip in Korean) written by a Chinese poet Toumu(or Doomok in Korean) during the Tang Dynasty of China, Chang Po-go was appointed as a ‘Goon-Joong-So-Jang’(a junior commander in Army, Jun Zhong Xiao Jiang in Chinese) at the age of 30, and it seems that he was born in around 790.

According to the record of 'Sam-Gook-Sa-Ghi'(A History of Three Kingdoms), when King Moonseong of Shilla Dynasty wanted to marry Chang Po-go's daughter as his second wife, the court officials opposed the marriage for reason that Commissioner Chang was from an island. From this record, it is presumed that he was from 'Heado'(an island name) or from a coastal area, and his social status might have been a commoner or a person of low class family.

His hometown is assumed to be Cheong-Hae-Jin, today's Wando island in Southwestern part of Korean Peninsula. This assumption is based on the fact that he chose Cheong-Hae-Jin as the headquarters of his Maritime Kingdom and on the story of his hometown junior. According to the story, when Jeong Nyeon who was a junior from Chang's hometown lost his job at Tang in China, after suffering from starvation and cold at Si Zhou area, he decided to come back to his hometown. “It's better to die fighting for my country than to die from hunger and cold. Not to mention, now I can die in my hometown, and I wish nothing more," said Jeong. He then came back to Cheong-Hae-Jin.
