The term "wokou" literally means "dwarf pirates", with "wo" (倭; "dwarf") being the Classical Chinese pejorative for the Japanese people. The term was first used to refer to Japanese invaders on the Gwanggaeto Stele in 414 AD, and was reused in 1223 when Japanese pirates raided the Korean coast. These pirates eventually broadened their area of operations to the coast of China, and were active throughout East Asian coasts up to the establishment of the Ming dynasty in China. However, by the 16th century, the pirates nominally called the "wokou" were mostly not Japanese, but actually Chinese. According to the "History of Ming" and other contemporary Chinese records, only thirty percent of the 16th century wokou were Japanese, while seventy percent were ethnic Chinese. Moreover, the Chinese played the leading role in these later wokou raids, with the Japanese and those of other nationalities being mere associates and hired hands.
