About 85 years (c. 1270–1356) when Goryeo kept its kings but was subordinate to Mongol Yuan China.
See it on the Korean History map →What happened
Korean historians call this the Yuan interference period (원 간섭기). Goryeo's crown princes lived in the Yuan capital, Dadu (Beijing), married Mongol princesses, and as kings received posthumous names beginning with chung ('loyal'). Yuan ruled parts of the north and Jeju directly, and made Goryeo supply ships, troops and food for its failed invasions of Japan in 1274 and 1281. Goryeo also sent tribute women, eunuchs and falcons; one such woman became Yuan's Empress Gi. King Gongmin broke away in 1356.
Why it matters
Foreign control brought hardship but also Neo-Confucianism, the Yuan calendar and wider trade, setting up ideas behind Joseon's founding.
How we know
The Goryeosa and Yuan shi; royal marriage and tribute records; and Mongol loanwords in Korean for horses, falconry and court life.
Still debated
Scholars disagree on what to call Goryeo then: a vassal, a semi-colony, or a 'son-in-law state' that kept real self-rule.

▸Mongol invasions of Korea led to Goryeo under Yuan overlordshipWell documented
The connection
In 1259 the crown prince, later King Wonjong, traveled to submit and met Khubilai, who promised not to change Goryeo's customs. So Goryeo kept its dynasty, but its kings married Mongol princesses from 1274, raised heirs in Dadu, and lost the northeast to direct Mongol rule. The war's end made Goryeo subordinate to Yuan.
When and how
1259–1274, between the Goryeo court and Khubilai Khan's court in China.
How we know
The Goryeosa and the Yuan history both record the submission, Khubilai's promise and the royal marriages.
Debates and open questions
How much real self-rule Goryeo kept, and whether 'colony,' 'vassal' or 'son-in-law state' fits best, is debated.
▸Goryeo under Yuan overlordship set up the Ming dispute behind Wihwado RetreatMostly agreed
The connection
Yuan had ruled Goryeo's northeast directly as the Ssangseong Commandery until 1356. When Ming replaced Yuan, it announced in 1388 that it would take those same lands as a Cheollyeong Commandery. King U and Choe Yeong answered by ordering an attack on Ming's Liaodong; Yi Seong-gye, sent against his will, turned back at Wihwa Island.
When and how
1388, at Kaesong and on the Yalu River; King U, General Choe Yeong, Yi Seong-gye and the Ming Hongwu Emperor.
How sure are we?
Goryeosa and Ming records both note the Cheollyeong plan and its basis in the old Yuan border.
Debates and open questions
Whether Ming truly meant to annex the land or was bargaining is unclear; it later dropped the plan. Pro-Yuan and pro-Ming factions also shaped Goryeo's decision.
