Pyeonggang
P'yŏnggang lies on a broad upland plain north of Ch'ŏrwŏn, where rivers cut deep valleys through the old lava landscape. It received its name in 1018 under Koryŏ and was governed as a dependency of Tongju. Its position on a route through the interior brought hardship during invasions: Khitan forces passed through in 1217, and Japanese armies advanced through the district in 1592.
