The north-west frontier zone (Bukgye) is run by a military commissioner (byeongmasa), with his seat at Anju, where the great protectorate of Anbuk (the pacified north) stands on the Cheongcheon river and the border army musters [not yet checked against the source].
Under him are the frontier towns (jin) along the Yalu and the long wall: Uiju, Heungwa, Yongju, Cheolju, Seonju, Guju and the rest of the wall's list (English Wikipedia names nineteen). Quiet since the 1120s, the zone's tax is kept for its own garrison, not sent to the capital [not yet checked against the source]. His duties are to watch the Yalu, receive Jin embassies at Uiju, license the border market and report to the Ministry of War, which Choe holds.
His name is not known and we give none. The Khitan refugees who cross the Yalu in 1216 are the next real test.
Who he is
- Title
- Military commissioner of the North (Bukgye byeongmasa) with the protectorate of Anbuk (Anju)
- Since
- not known
- Confidence
- low
No source we could read names the holder in 1200
What it holds
- The Bukgye frontier zone and its garrisons
- The towns of the wall: Uiju, Seonju, Guju and others
- The Anju protectorate and the Cheongcheon crossing
How things stand that morning
Quiet. No Jin or Khitan campaign has touched the zone since the 1120s; the wall is a belt of old works, not a front.
Threats
- A Jin or Khitan crossing (not before 1216)
- A rising in the north-west, which has risen before: Myocheong in 1135, Jo Wi-chong in 1174 to 1176 (Yi Ui-min put it down)
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- 1216Khitan bands cross the Yalu and enter Bukgye.Depends on: Mongol pressure on the Khitan of Liaodong Stopped by: Jin success against them
