During the time of Silla Kingdom, this region is the administrative center of Saengseoryang-gun, which governed the area of today's Seosaeng-myeon, Onsan-eup and Onyang-eup.

In the early Joseon dynasty, a naval manhoyeong stationed in Seosaengpo in the eastern part of the region. Following the Japanese invasions of Korea in 1592, the commander of the manhoyeong was promoted to the rank of naval dongcheom Jeoljesa. In the 32nd year of King Gojong's reign, as the navy was being abolished, the region was organized into Seosaeng-myeon and put under the direct jurisdiction of dongcheom Jeoljesa.
