Boseongbu

Posŏngbu lay in the mountainous Chinbo country of southeastern Korea. Early in the Koryŏ dynasty it was formed by joining the older districts of Chinbo and Chinan, and in 1018 it became dependent on Yeju. Raids later burned its government buildings and dispersed its inhabitants. The Joseon court appointed a magistrate in 1394 and restored the name Chinbo in 1413.
