On the morning of 1 January 1200 Goryeo is a Buddhist kingdom of rice, hemp, paper, ginseng and celadon, with its trade running through the river port of Byeokrando.
It has two centres of power that must not be confused. In the palace at Gaegyeong (Kaesong) sits King Sinjong, b. 1144, put on the throne by Choe Chung-heon in the 9th lunar month of 1197; he signs the grants and keeps the rites, and has no true power. Choe has no royal title. He is Minister of War with charge of the Ministry of Personnel (Chinese Wikipedia, for 1199), which means every appointment in the kingdom, and he stands on a coup party of kin and friends, on the officers' council (Jungbang) that he captured, and on the estates of the man he killed, Yi Ui-min (April 1196).
The deposed king Myeongjong (b. 1131) is shut in Changnak Palace; his heir Wang O (b. 1152) was sent to Ganghwa. The kingdom is five circuits (do: Yanggwang, Gyeongsang, Jeolla, Gyoju, Seohae), two frontier zones (gye: Bukgye in the north-west, Donggye in the north-east), the capital district round Gaegyeong, three secondary capitals (Seogyeong, Dongkyeong, Namgyeong) and the island county of Tamna.
Beneath the officials stand the local clerks (hyangni), who really carry the tax, and a ring of special villages (so, bugok) that pay in goods and labour. The strain is from below: Manjeok's slave plot at the capital (1198, put down), the hill and coast risings round Myeongju and Samcheok (1199, not pinned how they ended), and, on the likely course, Jinju from the spring of 1200 (the slave rising under Jeong Bang-ui, not yet begun on 1 January). Abroad, the Jin hold the Yalu and the Tumen; the Song have had no formal tie since 1127; Japan has none; the Mongols are not yet heard of.

Overlord
The Jin emperor Zhangzong (era Cheng'an) as nominal suzerain: Goryeo has been a Jin tributary since 1126. No Jin officer sits in Goryeo and the Jin does not interfere in appointments.
What the realm holds
- Gaegyeong (Kaesong) and the capital district (Gyeonggi), with Ganghwa and the Yeseong port of Byeokrando
- Secondary capitals: Seogyeong (Pyongyang), Dongkyeong (Gyeongju), Namgyeong (Hanyang, modern Seoul)
- Circuits: Yanggwang, Gyeongsang, Jeolla, Gyoju, Seohae; frontier zones: Bukgye, Donggye
- Tamna (Jeju) as a county under magistrates and native chiefs
- A claim to Ulleung, with no settlement
- The western and southern island chains (Baengnyeong to Jindo, Heuksan, Wando, Namhae, Geoje)
How it was acquired
Founded by Wang Geon in 918, it took the Later Three Kingdoms by 936. The military coup of 1170 ended civil rule; Choe's coup of 1196 to 1197 ended the generals' scramble by putting one house on top. The Choe house rules until 1258.
Allies and rivals
Jin: nominal suzerain, quiet frontier since the 1120s, licensed border market at Uiju. Song: no state mission since 1127, merchants only. Japan: no state tie; merchants from Tsushima and Hakata at Geumju. Khitan remnants live under Jin rule in Liaodong (their invasion of Goryeo is 1216). Inside: Choe's own relatives, the generals, the Buddhist houses, and the risers of the hills and coasts.
The realm that morning
Held: the peninsula south of the lower Yalu and the long wall (Cheolli Jangseong), with the north-east edge at Jeongpyeong and Hwaju; Jeju as a county. Not held: the Hamhung plain and everything north of Jeongpyeong (Jin's Helan country and Jurchen villages), and the upper Yalu and the Paektu uplands (Jin and Jurchen). Choe rules by appointments and by his own men; the Tobang (private guard) is NOT yet raised (it comes in Sinjong 3, 1200, month not pinned).
Manjeok's plot (1198) is put down. The east (Myeongju, Samcheok) was in revolt in 1199; the campaign board says it was bought off; we could not confirm. Jinju has not risen; Gyeongju is quiet but remembers Kim Sa-mi and Hyo-sim (1193 to 1194).
Wealth
Rice tax from the southern granaries (Jeolla, Gyeongsang) carried by sea and river to Gaegyeong; hemp and ramie cloth, paper, ginseng, celadon (Gangjin, Buan), salt, iron and copper from special villages, Jeju horses and abalone; sea trade with the Song at Byeokrando. Private estates (nongjang) and tax-free temple lands have eaten the old rank-land system; Choe's Ten Articles of 1196 complained of it.
Military
The old central guards (the Two Armies and Six Guards) are nominal. Real force is in the hands of the generals' households and, on the likely course, Choe's guard (the Tobang, raised during 1200 and not in being on 1 January). The frontier armies of Bukgye and Donggye answer to military commissioners (byeongmasa); provincial elite units (byeolcho) and local levies are called out by the circuits. No numbers are given.
Threats
- Choe's own kin and clients (the Chung-su affair of 1197 to 1198 shows how)
- Generals who want his place
- Buddhist houses and armed monks, one of whose plots on Choe is reported without date
- Slave and peasant rising: Jinju in the spring of 1200 and Gyeongju in 1202 (both the likely course, not yet begun)
- The Jin, if the throne is shaken (no sign)
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.
In 1200
- Sinjong 3 (1200), month not pinnedChoe restores the Tobang, the private guard once kept by Gyeong Dae-seung (1179 to 1183), organised in rotas to guard his house and escort him.Depends on: Repeated plots on his life (Chinese Wikipedia) Stopped by: His death, or a coup of the generals before he builds it
- Sinjong 3, 4th lunar month (about April to May 1200) [not yet checked against the source]The Jinju slaves and townsmen rise under Jeong Bang-ui; the unrest spreads to Geumju (Gimhae) and Hapju.Depends on: Local clerks' exactions and the slave grievance at Jinju Stopped by: A timely concession by the circuit officer, or the rising being betrayed
- Spring 1200, month not knownJinul moves his Samadhi and Prajna Society from Jirisan to Songgwangsan (Gilsangsa).Depends on: The abbot's invitation and a patron's help Stopped by: Illness, a rising on the road, or no hall ready
- 12th month of Sinjong 3 (about December 1200 to January 1201) [not yet checked against the source]Yi Gyu-bo is dismissed from his post at Jeonju.Depends on: A slander against him Stopped by: None needed: minor
Later, on the likely course
- Sinjong 4 to 5 (1201 to 1202)Choe takes more offices; from 1202 he handles civil and military appointments from his own house (English Wikipedia).Depends on: His hold on the king and the Jungbang Stopped by: A rival general
- Autumn to winter of Sinjong 5 (1202)Gyeongju's 'Silla restoration' rising; Tamna revolts; Myeongjong dies in Changnak Palace (3 December 1202 in English Wikipedia).Depends on: Gyeongju grievance and Choe's weak grip on the south-east Stopped by: Choe sending a stronger force at once
- Sinjong 7 (1204), about January to FebruarySinjong, ill, abdicates at Choe's demand and dies 15 February 1204 (English Wikipedia); Huijong succeeds.Depends on: Choe's choice of successor Stopped by: Huijong's dying earlier
Places of note
- Gaegyeong, the capital: Palace (Manwoldae), royal temples and the Choe house
- Seogyeong, the Western Capital: Second capital and the north-west's chief seat
- Uiju, the Yalu gate: Jin embassies cross here; the licensed border market
- Byeokrando, the sea gate: Song merchants and the mouth of the Yeseong river
- Tamna (Jeju): Island county with native chiefs
Where the sources disagree
- The campaign board entry place names Gyeonggi-do, Pyeongan, Hamgyeong, Gangwon-do and Jeolla-do in region labels are later or modern; the units of 1200 are the capital district (Gyeonggi), five circuits and two frontier zones (Bukgye, Donggye). The campaign board's 'Gyeonggi' is the capital district round Gaegyeong only.
- The campaign board entry posu-jiuliancheng: a Jin fort on the Chinese bank; the point falls on the Korean side; we write it as an anchor with realm jin and not as a Goryeo town.
- English Choe Chung-heon page puts Choe Chung-su's death in 1200 in the text and 1197 in the infobox: we settle it as soon after Sinjong's accession (late 1197 or early 1198), before Manjeok's plot (5th month 1198), so he is dead on 1 January 1200 (see Choe Chung-su).
- The campaign board entry says Jinju's storm has not yet broken: agreed. The campaign board entry says the Tobang is raised during 1200: agreed (Chinese Wikipedia, Sinjong 3).
- The campaign board entry gilsangsa-songgwangsan says the society is 'on the road from Jirisan' on 1 January: not confirmed; our recollection is that Jinul is at Sangmuju hermitage on Jirisan and moves later in 1200 (the likely course).
Evidence: The outline of 1196 to 1204 is well attested in English and Chinese Wikipedia, which follow the Goryeosa. The Goryeosa text, Goryeosa jeoryo and the Korean Wikipedia were not reachable (Wikisource and ko.wikipedia refused), so months of events of 1197 to 1200, names of frontier commanders and the local detail rest on recollection and are marked [not yet checked against the source] or 'not pinned'.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: The outline is a rough closing of the modern districts and follows no 1200 survey; the north-east edge near Jeongpyeong and the Yalu bank above Sakju are the least certain lines.
