Yi Kang, the Prince Imperial Uihwa (also Euihwa), (born 30 March 1877 – 15 August 1955) was the fifth son of Emperor Gojong of Korea and his concubine, Lady Chang, who was a court lady-in-waiting.
Prince Yi Kang was not the Crown Prince, even though he was older than his brother Prince Imperial Yeong, due to the status of his mother.
He was only recognized as a legitimate prince with the name of Yi Kang and was titled Prince Uihwa with the style of Royal Highness in 1891, following a decree issued by his father.
He married Lady Gim Sudeok, later known as the Princess Duk-in (22 December 1879 – 14 January 1964), a daughter of 1st Baron Gim Sajun.
His son finally became the head of the Imperial House in 2005.
