Cheomhae of Silla (r. 247–261, died 261), often known by his title Cheomhae Isageum, was the twelfth ruler of the Korean kingdom of Silla. He was a Seok, and the younger brother of the previous king, Jobun.[1]
The Samguk Sagi also reports that the Cheomhae forged a truce with Goguryeo, and that his reign saw repeated clashes with Baekje. Cheomhae's kinsman, the general Uro, was slain by the people of Wa in the year 250.[2]
The defeat at this time dealt a serious blow to Silla. Later, Silla became close to Baekje and Goguryeo to guard against Japan even though Baekje had close relations and was allied with Japan. Given that some of the conquered city-states reappeared as Gaya, some city-states became independent.[3] It was not until the reign of King Jijeung that Silla overcame the aftereffects and resumed its conquest.
