Historical Evaluation on Chang Po-go

The first evaluation on Chang Po-go was done by a Chinese poet Toumu(Doomok in Korean, 803-852), the author of a collection of books called 'Beon-Cheon-Moon-Jip'. This collection was written during the Chang Po-go's lifetime, and so this record is evaluated to be the closest to the truth. Doomok compared Chang Po-go to a person Guo-Fen-Yang(Gwak Boon-yang in Korean), who was active during the An Lu-Shan's rebellion. He also described Chang Po-go as an intelligent, good man and one of the most distinguished persons in the East. This shows that Chang Po-go was highly respected Shilla person in China at that time.

A Chinese history book, 'Xin Tang Shu'(Shin-Dang-Seo in Korean) praised Chang Po-go as a great man by comparing him to two Chinese great men, Qi Xi(Ki Hae in Korean) during the Qin Dynasty(221-206 BC) and Guo-Fen-Yang from the Tang Dynasty. During the Koryo Danasty, Kim Boo-sik, the author of Sam-Gook-Sa-Ghi, described in the biography of 'Kim Yoo-sin, "Even if General Ulji Moon-deok was a clever commander and Chang Po-go was a righteous and brave man, without Chinese history books, we wouldn't have known their existence and greatness.' From this description, we can tell the objective evaluation on Chang Po-go had already begun during the Koryo Dynasty.


In recent years, some intellectuals in Korea realized that most of the leading countries in the world history were naturally the powerful maritime countries which had control over the sea. Chang Po-go is now revaluate a pioneer who saw through the importance of advancing to the ocean and took a leading role in shifting tribute trade (public trade) to private trade.


In Korea, professor Kim Sang-gi wrote the first academic article on the achievement of Chang Po-go and asserted that he was literally 'the Builder of Maritime Kingdom' who personally practiced the principle -'A person who controls the sea rules the world itself'. Professor Edwin O. Reichauer of Harvard University, who was American Ambassador to Japan, called Chang Po-go as 'The Trade Prince of the Maritime Commercial Empire'. In Korea nowadays, the movement of reevaluation on Chang Po-go keeps spreading among some scholars steadily.
