Early life

Yi and Ito hirobumi

The prince was born on 20 October 1897 at Deoksu Palace in Seoul as the seventh son of Gojong, the Gwangmu Emperor. His mother was the Honorable Princess Consort Eom Seon-yeong, a palace attendant, who was posthumously awarded the title of Princess Sunheon. He was also the younger half-brother of Emperor Sunjong and Prince Imperial Ui. He was titled Prince Imperial Yeong in 1900, and became the crown prince in 1907, despite being younger than Prince Ui. Prince Ui's support base at court was not strong because his own mother, Lady Jang, had already died.

In December 1907, he was taken to Japan and was enrolled at Gakushūin Peers' School, and upon graduating entered the Imperial Japanese Army Academy, both in Tokyo. Graduating from the academy on 25 May 1917, he was commissioned a second lieutenant in the infantry on 25 December, and steadily rose up the ranks, receiving promotions to lieutenant (April 1920), captain (July 1923) and to major (August 1928).

In 1920, he married Princess Masako of Nashimoto (born 4 November 1901 – 30 April 1989(1989-04-30) (aged 87)), the eldest daughter of H.I.H. Lieutenant-General Prince Nashimoto Morimasa, on 28 April 1920 at Tokyo. Prince Morimasa was promoted General in 1922 and was appointed a Gensui in 1932.

In 1910, when the Empire of Korea was annexed by Japan and Emperor Sunjong was forced to abdicate, Yi Un was titled His Royal Highness The Crown Prince of Korea. On 10 June 1926, upon the death of Emperor Sunjong and his funeral, he became King Ri of Korea (demoted Korean sovereign's title after the Japan-Korean Annexation Treaty).

Prince Yi Eun (also known as Prince Ri Gin in Japan) served in the Imperial Japanese Army as Commanding Officer of the 59th Regiment, the 4th Depot Division, and then later the 51st Division. He received further promotions to lieutenant colonel (August 1932), colonel (1 August 1935), major general (15 July 1938) and to lieutenant general (2 December 1940). He also served in the Imperial Japanese Army Air Force with the rank of lieutenant general, commanding 1st Air Army. He further served as Instructor at Military Staff College, attached to the Inspectorate General of Military Training and became a Member of the Supreme War Council during wartime.^[1]

Later life

After Korea became independent of the Empire of Japan in 1945, Prince Yi Eun (also known as H.M. King Ri of Korea) requested permission from President Syngman Rhee to be allowed to return to Korea with his family but was refused. The prince was offered the position of Korean Ambassador to the Court of St. James's in 1960, but refused on the grounds of illness.

In November 1963, President Park Chung-hee granted permission for Prince Yi Eun and Crown Princess Bangja to return to Korea. By that time, Prince Yi Eun was unconscious from cerebral thrombosis. He received treatment at St. Mary's Hospital in Seoul.

In his final years, Prince Yi Eun lived at Nakseon Hall, Changdeokgung Palace, the former residence of the Korean Imperial Family in Seoul, with Bangja and his younger sister Princess Deokhye. Seven years after returning to his country, he died on 1 May 1970 at Nakseon Hall, Changdeok Palace, Seoul. He was buried at Hongreung in Namyangju, near Seoul; he is known posthumously as Yi Un, Crown Prince Euimin of Korea.
