Yi Ha-eung, father of King Gojong, who ran Joseon as regent from 1863 to 1873 with domestic reform and armed isolation.
See it on the Korean History map →What happened
When his 11-year-old son became King Gojong, Yi Ha-eung took power as Heungseon Daewongun (흥선대원군), a title for a king's father who never reigned. He broke the grip of the Andong Kim in-law clan, shut most private Confucian academies (seowon), made yangban households pay the military cloth tax, and rebuilt Gyeongbokgung at crushing cost. Against the West he renewed Catholic persecution, fought off French (1866) and American (1871) raids, and raised steles calling peace with Westerners treason. Gojong's court ended his rule in 1873.
Why it matters
His decade stiffened Joseon's resistance to the West just as Japan was modernizing, and his feud with Queen Min split the court for 25 years.
Legacy and how we know
Court records, surviving anti-foreign steles (cheokhwabi), his Seoul residence Unhyeongung, and French, American and Japanese accounts.
Still debated
Historians still argue whether his isolation was a fatal mistake or a reasonable defense, given how Western powers were treating China.

Connections (5)
▸Gyeongbokgung Palace was rebuilt by Heungseon DaewongunWell documented
The connection
Gyeongbokgung had lain in ruins since it burned in 1592 during the Japanese invasion. To restore royal prestige, the Daewongun rebuilt it from 1865 with hundreds of buildings. He paid with forced 'voluntary' donations, labor drafts and a debased 100-cash coin (dangbaekjeon) that set off inflation and turned many against him.
When and how
Seoul, 1865–1868; main halls finished 1867, and Gojong moved in the following year.
How we know
Court records of the rebuilding and surviving dangbaekjeon coins; the rebuilt halls themselves still stand.
Debates and open questions
The full cost is unknown, and how much the project's burden caused his 1873 fall, versus court politics, is debated.
▸Heungseon Daewongun intensified Catholic persecutions in JoseonWell documented
The connection
After Russian ships appeared in 1864–65, the Daewongun briefly explored using French missionaries to seek an alliance against Russia. When that went nowhere and court pressure grew, he ordered the 1866 Byeongin persecution: nine French priests and, by estimates, about 8,000 Korean Catholics were killed over several years.
When and how
Seoul and across Korea, 1866–1871; executions at Saenamteo and Jeoldusan on the Han River.
How we know
Court records, Father Félix-Clair Ridel's reports and Catholic martyr lists; the Jeoldusan shrine marks an execution site.
Debates and open questions
Death tolls vary widely; why he turned from contact to persecution (court politics, Qing anti-Christian moods, rivals' pressure) is debated.
▸Heungseon Daewongun repelled French campaign against Korea (Byeonin yangyo)Well documented
The connection
The Daewongun rejected talks, mobilized troops, including tiger hunters from the north, and ordered the Han River defended. After a Korean ambush at Munsusanseong and a defeat at Jeongjoksanseong, the French left. He presented this as proof that Joseon could keep Westerners out, and stepped up both persecution and coastal defense.
When and how
Ganghwa Island and the Han River mouth, October–November 1866; General Yang Heon-su commanded at Jeongjoksanseong.
How we know
Korean court records and French naval reports agree on the withdrawal, though not on losses.
Debates and open questions
Whether the French left because of defeat or because Roze judged the raid pointless before winter is debated.
▸Heungseon Daewongun rebuffed United States expedition to Korea (Sinmi yangyo)Well documented
The connection
The Daewongun refused all US letters and gifts, insisting Korea would not deal with Westerners. The Americans won every fight on Ganghwa, but with no orders to invade further and no one willing to negotiate, they sailed away. He then raised anti-foreign steles (cheokhwabi) across the country.
When and how
Ganghwa Strait, June 1871; the Daewongun in Seoul, Rear Admiral Rodgers and Minister Frederick Low offshore; the fleet left on July 3.
How we know
US and Korean records agree the fleet left without a treaty; many cheokhwabi still stand.
Debates and open questions
Whether his hard line showed strength or a misreading of the world is debated; he had little view of how fast Japan was modernizing.
▸Heungseon Daewongun was regent for his son King and Emperor GojongWell documented
The connection
When King Cheoljong died without a son in 1863, Dowager Queen Sinjeong chose the Daewongun's young son as heir, and the father governed in the boy's name. In 1873, as Gojong came of age and Queen Min's relatives gained influence, a memorial by scholar Choe Ik-hyeon gave the king cover to rule directly. Father and son remained rivals.
When and how
Seoul, January 1864 (still the 12th lunar month of 1863) to late 1873.
How we know
The Annals and court memorials, including Choe Ik-hyeon's 1873 memorial attacking the regent's policies.
Debates and open questions
The formal regency at first belonged to Dowager Queen Sinjeong; how the Daewongun's real but unofficial power worked day to day is debated.
