Maritime Trade Emperor, Chang Po-go, during the 9th Century


Chang Po-go (A.D. ? ~ 841)

Since A.D. 828, Chang Po-go developed Cheong-Hae-Jin(a kind of special Military and Administrative Base) in Wando island, Jeonnam Province, Korea into an international trading port which made free trade possible; and he devoted himself to assembling the commercial abilities of people during the 9th century who already had advanced to the major communication and trading areas of China and Japan.

He then established a global network which dominated not only triangular trade among Korea, China, and Japan, but also the trade between the South and North areas within China, as well as merchants from Persia and Southeast Asia. From that on, he made Korean Peninsula the economic center of Northeast Asia, and he was the first person who controlled the maritime trade in the East in history.

Also his maritime activities were not just trade, but also they were comprised of various commercial activities concerned with trade such as exporting Chinese ware produced by themselves giving translation and guidance service for the trading activities of envoys from the three nations, Korea, China, and Japan; transporting travelers; building and repairing of ships; and giving religious and cultural support. Through combining military, manufacturing, and commerce, he presented a new model of trade and business for various fields and made Korea the trading hub of Northeast Asia. He was a person who personally proved the old saying, “He who controls the sea, shall control the world itself" to be true.
