He was the eldest son of King Chungnyeol. His mother was a Yuan royal, Princess Gyeguk, a daughter of Khublai Khan also known by her Mongolian name/title Qutlugh-kelmysh.
He is sometimes known by his Mongolian name, Ijirbuqa (益知禮普花, means "small ox"). Adept at calligraphy and painting, rather than politics, he generally preferred the life of the Yuan capital Beijing to that of the Goryeo capital Kaesong. In 1277, Chungseon was confirmed as Crown Prince.
In the following year he travelled to China and received his Mongolian name.
Chungseon"s mother died in 1297, and this was followed by a violent purge brought on by allegations that she had been murdered. Perhaps upset by these evens, King Chungnyeol petitioned Yuan to abdicate the throne and was accordingly replaced by Chungseon in 1298.
Faced with intense plotting between the faction of his Mongolian queen and his Korean queen, Chungseon returned the throne to his father shortly thereafter. He became the Prince of Shenyang, a new title, in 1307 or 1308.
After his father"s death in 1308, Chungseon was obliged to return to the throne of Goryeo and made efforts to reform court politics, but spent as much time as possible in China.
The title King of Shenyang was renamed Prince of Shen in 1310. He is a very rare case of personal unions in East Asia. He retired from the throne in 1313, and was replaced by Chungsuk of Goryeo.
