He was the eldest son of King Chaekgye. He became king upon Chaekgye's death in 298 when he was killed in battle during the 13th year of his reign. The Samguk Sagi records that "from his youth he was bright and intelligent, and in his performance of rites he was bold and upright. His father the king loved him, and never separated him from his side".
He continued to wage war against the Chinese Lelang commandery whose forces had killed his father. In 304, he captured a western district of the Lelang commandery. According to the Samguk Sagi, the governor of the commandery thereupon sent an assassin who poisoned him.
