Yangam

Yangam was a fortified district in the inland country east of Sŏngch'ŏn. During the Red Turban invasion of 1361, the Koryŏ commander Yi Pangsil asked that its people and grain be moved to the stockade at Chŏllyŏng, together with those of neighbouring districts. In 1396 the new Joseon government combined Yangam with Sudŏk to form the county of Yangdŏk.
