Buryeong

Buryŏng lies in the mountainous northeastern country between the coast and the Tumen frontier. In the fifteenth century, the Joseon court used places in this district to secure its northern approaches. Kyŏngwŏn's administrative seat, withdrawn from the lower Tumen after a Jurchen attack, was re-established here in 1417 and governed land reaching northward to the river until 1434. Pugŏ Fortress also served as a frontier outpost.
