Prince Imperial Yeong, Yi Un, Crown Prince Uimin (also Euimin), also known as Yi Un, Yi Eun, Lee Eun and Un Yi (20 October 1897 – 1 May 1970), was the 28th Head of the Korean Imperial House, an Imperial Japanese Army general and the last crown prince of Korea. In 1910, when the Korean Empire was annexed by Japan and Emperor Sunjong was forced to abdicate, Yi Un was titled His Highness The Crown Prince of Korea. On 10 June 1926, upon the death of Emperor Sunjong, he became His Highness King Yi of Changdeokgung in Japan. Yi Un achieved the rank of Lieutenant General in the Imperial Japanese Army, commanded Japanese forces in China and served as a member of the Supreme War Council. After World War II he was refused entry to Korea, and his Japanese titles were removed by article 14 of the new Constitution of Japan in 1947. In 1920, he married Princess Masako of Nashimoto (born 4 November 1901 – ), the eldest daughter of Prince Nashimoto Morimasa, on 28 April 1920 at Tokyo. Early life 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 on the initiative of Itō Hirobumi to be enrolled at Gakushūin Peers' School. The move was meant to ensure that the Korean royal family would not take any further anti-Japanese actions following The Hague Secret Emissary Affair. Japanese Emperor Meiji, who largely ignored his own grandchildren, devoted a lot of attention to Yi Un, acting as his guardian. Itō would bring Yi Un whenever he was visiting the princes Hirohito, Chichibu and Takamatsu. Meiji apparently stopped seeing Yi Un so frequently after Ito's assassination. Yi Un was allowed to visit Korea again only after the death of his mother in 1911. Military career In September 1911, the prince was enrolled in the second year of
