See it on the Korean History map →What happened
Goryeo (고려) was founded in 918 by Wang Geon, who reunified the peninsula by 936 and ruled from Gaegyeong, today's Kaesong in North Korea. Buddhism was the state faith, while Confucian-trained officials, chosen partly by exams from 958, ran the government. Goryeo fought off the Khitans, lived through a century of military rule (1170–1270) and nearly 30 years of Mongol invasions, then served under Yuan overlordship until 1356. Its 34 kings ruled 474 years until Yi Seong-gye took the throne in 1392.
Why it matters
It made the peninsula one state for the next thousand years, produced celadon, the Tripitaka Koreana and metal type, and through traders gave the West the name 'Korea.'
How we know
The Goryeosa (History of Goryeo), compiled under Joseon in 1451; Chinese accounts such as Xu Jing's 1123 report; tombs, temples, and Kaesong's palace site Manwoldae, dug jointly by North and South Korea from 2007 to 2018.
Still debated
How much Goryeo's image, from Buddhist excess to late decay, reflects the bias of the Joseon scholars who wrote its official history.

Connections (12)
▸Balhae sent refugees and its prince to GoryeoWell documented
The connection
As Balhae collapsed, waves of its people fled south to Goryeo from the 920s into the 970s. The Goryeosa says the crown prince, Dae Gwang-hyeon, arrived with tens of thousands of followers; Wang Geon gave him the royal surname Wang, a place in the royal register, and the right to keep up rites for his ancestors.
When and how
In waves from about 925 to 979; the Goryeosa dates the prince's arrival to 934, though some records suggest 925.
How we know
Repeated Goryeosa entries record groups of arrivals, often with numbers; several Goryeo families later traced their descent to Balhae refugees.
Debates and open questions
How many came in all is unknown, and estimates vary widely; whether Goryeo welcomed them as kin or as useful manpower is debated.
▸Later Three Kingdoms ended in reunification by GoryeoWell documented
The connection
Wang Geon won by mixing battle and diplomacy. Victory at Gochang in 930 swung regional lords to his side; generous treatment of Silla led its king to surrender in 935; a family split in Later Baekje sent Gyeon Hwon over to him. At Illicheon in 936 Goryeo destroyed Later Baekje and ended the division.
When and how
930–936, at Gochang (Andong), Gyeongju and Illicheon near Gumi; Wang Geon, Silla's King Gyeongsun, Gyeon Hwon and his son Singeom.
How we know
The Goryeosa and Samguk sagi agree on the sequence and dates of the final campaigns.
Debates and open questions
Some call 936 Korea's first true unification, since Goryeo also absorbed Balhae refugees; others give that title to Silla in 668. Both left Manchuria outside.
▸Unified Silla surrendered peacefully to GoryeoWell documented
The connection
With his realm shrunk to Gyeongju, Silla's last king, Gyeongsun, chose in 935 to hand it to Goryeo rather than fight on. Wang Geon received him with honor, married him to a daughter and made him overseer of Gyeongju. Silla nobles joined Goryeo's elite, and Wang Geon's Silla-born wife became grandmother of King Hyeonjong, ancestor of later Goryeo kings.
When and how
Late 935 (lunar 11th month), when Gyeongsun led a long procession from Gyeongju to Goryeo's capital at Kaesong.
How we know
The Samguk sagi's Silla annals end with the surrender; the Goryeosa records the terms and the marriages.
Debates and open questions
The Samguk sagi says the crown prince objected and withdrew to the Geumgang Mountains in hemp clothes; later legend grew around him. How willing the surrender was is debated.
▸Wang Geon (King Taejo of Goryeo) founded GoryeoWell documented
The connection
Made king in 918, Wang Geon named his state Goryeo and in 919 moved the capital to his home base, Songak, renamed Gaegyeong (Kaesong). He bound regional lords to the throne through 29 marriages, grants of the royal surname and land, and left Ten Injunctions telling his heirs to honor Buddhism and keep pushing north.
When and how
918–943, first at Cheorwon, then at Gaegyeong (Kaesong), now in North Korea.
How we know
The Goryeosa records his reign in detail; his tomb, Hyeolleung, stands near Kaesong.
Debates and open questions
His many marriages left princes by different mothers, and succession fights followed his death in 943; the Ten Injunctions' authenticity is also debated.
▸Goryeo took its name from GoguryeoWell documented
The connection
Goguryeo itself had shortened its name to Goryeo by the 5th century. Gung Ye's state was called Later Goguryeo, and Wang Geon kept the name Goryeo to claim Goguryeo's heritage and its old northern lands. He rebuilt Pyongyang as a Western Capital and pushed the border north. Through Goryeo, Western traders later learned the name 'Korea.'
When and how
918, when Wang Geon took the throne at Cheorwon; Seo Hui restated the claim to the Khitans in 993.
How we know
Chinese histories and Goguryeo inscriptions use the name Goryeo (高麗) for Goguryeo from the 5th century; the Goryeosa records Wang Geon's Pyongyang policy.
Debates and open questions
China's state-backed Northeast Project (2002–2007) argued Goguryeo was a Chinese regional state unrelated to Wang's Goryeo; Korean scholars reject this, and the dispute is political as well as scholarly.
▸Goryeo–Khitan Wars ended in victory for GoryeoWell documented
The connection
After Gwiju, Liao gave up. Goryeo resumed envoys to Liao and used its calendar, a formal bow to the stronger neighbor, but kept all its land, including the six garrison districts on the Yalu. It walled its capital (completed 1029) and built a 'thousand-li' long wall across the north (1033–1044). Peace held for about a century.
When and how
1019–1044, from Kaesong to the northern frontier along the Yalu River; King Hyeonjong and his successors.
How we know
The Goryeosa and Liao history record the peace and resumed relations; parts of the long wall survive in North Korea.
Debates and open questions
Whether to call it a clear victory is debated, since Goryeo accepted nominal tributary status to Liao while keeping full control of its own affairs.
▸Goryeo celadon flourished under GoryeoWell documented
The connection
Goryeo's Buddhist court and aristocracy were celadon's main customers, buying tea bowls, ewers, wine vessels and incense burners. Kilns at Gangjin and Buan shipped wares by sea to Kaesong. In 1157 King Uijong even roofed a pavilion with celadon tiles. Song Chinese writers ranked Goryeo's glaze among the best in the world.
When and how
10th to 14th centuries, peaking in the 12th, at kilns in Gangjin and Buan serving the court in Kaesong.
How we know
Xu Jing's 1123 report, Goryeosa entries, celadon roof tiles excavated at Gangjin, and shipwrecks found with cargo tags addressed to Kaesong officials.
Debates and open questions
How the kilns were organized, as state workshops or partly private producers, and how inlay techniques spread among potters are still studied.
▸Goryeo military regime dominated GoryeoWell documented
The connection
For a century military strongmen ran Goryeo while kings stayed on the throne as figureheads. Choe Chung-heon deposed two kings and enthroned four; his house governed through the Directorate of Decree Enactment (Gyojeong dogam) and private guards, and controlled appointments and land. Civil officials who cooperated, such as Yi Gyu-bo, served the regime.
When and how
1170–1270, at the court in Kaesong and later on Ganghwa Island; Jeong Jung-bu, Yi Ui-min, then four generations of the Choe family.
How we know
The Goryeosa records each strongman's rise and fall in detail, though its Joseon compilers were hostile to military rule.
Debates and open questions
How much real authority the kings kept, and whether the regime was simply a dictatorship or also opened doors to men of lower birth.
▸Jeong Mong-ju stayed loyal to GoryeoWell documented
The connection
Jeong Mong-ju backed many of Yi Seong-gye's reforms but led those who wanted to keep the Wang royal house. In 1392, while Yi was hurt from a hunting fall, Jeong had his key allies exiled. Yi's son Yi Bang-won had Jeong killed, removing the last major obstacle; Goryeo fell three months later.
When and how
Spring 1392, in Kaesong; Jeong Mong-ju, Yi Seong-gye, Yi Bang-won and Jeong Do-jeon.
How we know
The Goryeosa and the Annals of King Taejo record the impeachments and the killing at Seonjuk Bridge.
Debates and open questions
Whether Jeong might eventually have accepted a new dynasty, and whether the famous poem exchange before his death really took place.
▸Yi Seong-gye (King Taejo of Joseon) deposed the last king of GoryeoWell documented
The connection
After Wihwado, Yi Seong-gye's faction removed King U (1388) and his young son King Chang (1389), claiming they were not true royal heirs, and installed King Gongyang. In 1392 Yi's allies deposed Gongyang and offered Yi the throne, ending Goryeo after 474 years.
When and how
1388–1392 in Gaegyeong (Kaesong); Yi Seong-gye, Jeong Do-jeon and allies against Kings U, Chang and Gongyang.
How we know
The Goryeosa, compiled under Joseon in 1451, and the Taejo sillok record the depositions and the reasons given for them.
Debates and open questions
The claim that U and Chang descended from the monk Sin Don, used to justify removing them, is widely doubted by modern historians.
▸Neo-Confucianism as state ideology rejected the Buddhist court culture of GoryeoMostly agreed
The connection
Late-Goryeo reformers blamed Buddhist temples, which held vast tax-free land and many slaves, for the kingdom's decay. Using Neo-Confucian arguments, they attacked Buddhism as wasteful and harmful to family duty. That critique justified the 1391 land reform and, in the end, a new dynasty.
When and how
Late 1300s in Gaegyeong (Kaesong), among officials teaching at the revived National Academy (Seonggyungwan), including Jeong Do-jeon and Jeong Mong-ju.
How sure are we?
Jeong Do-jeon's anti-Buddhist essays and late-Goryeo memorials preserved in the Goryeosa.
Debates and open questions
How corrupt Goryeo Buddhism really was is uncertain, since our sources come from its critics; some, like Jeong Mong-ju, wanted reform, not revolution.
▸Gang Gam-chan defended the capital of GoryeoWell documented
The connection
In 1010, as Liao's emperor neared Kaesong, Gang Gam-chan persuaded King Hyeonjong to flee south rather than surrender, keeping the dynasty alive. In 1018 he sent cavalry to guard Kaesong, and the Khitans turned back short of it. He then urged an outer wall for the capital, completed in 1029.
When and how
1010–1029, at Kaesong and on the roads south to Naju; Gang Gam-chan and King Hyeonjong.
How we know
The Goryeosa's biography of Gang Gam-chan and its annals of Hyeonjong record his advice and the building of the outer wall.
Debates and open questions
How decisive his 1010 advice was compared with Liao's own reasons to withdraw, and how much credit later tradition has added.
