, one of the Three Kingdoms of Korea.
Life
He was the younger brother of the previous ruler, King Chimnyu. According to the Samguk sagi, he ascended to the throne because the heir, later King Asin, was too young. However, according to the Japanese Nihon Shoki he usurped the throne by force.
He ordered numerous attacks against Goguryeo, which was expanding into Baekje territory from the north. In the year 386, he commanded all men living in Cheongmongnyeong (靑木嶺, present-day Kaesong), above the age of fifteen, to move north and west to defend the borders. He sent the noble Jin Gamo to attack the Goguryeo Dogon Castle, which was conquered. However, in 392 King Gwanggaeto of Goguryeo counterattacked and seized most of the Baekje territory north of the Han River. In the tenth month of that year, Goguryeo troops took Gwanmi Castle and threatened the Baekje palace.
According to the Samguk sagi, Jinsa died while hunting at a satellite palace in Guwon. According to the Nihon Shoki, Japanese diplomats were sent to Baekje to condemn Jinsa for disrespecting the Japanese emperor, and Jinsa was executed by Baekje as an apology. The Japanese diplomats then put Asin in power and returned to Japan.
