Empress Jingu was consort to Emperor Chuai (notionally 192  200 CE), she also served as Regent from the time of her husband's death in 209 until her son Emperor ?jin acceded to the throne in 269.No firm dates can be assigned to this historical figure's life or reign. Jing? is regarded by historians as a 'legendary' figure because of the paucity of information about her. Legend has it that she led an army in an invasion of Korea and returned to Japan victorious after three years. However, this theory is widely rejected even in Japan as there is no evidence of Japanese rule in any part of Korea at this early period. Some believe that Empress Jing?'s conquest is only based on the Gwanggaeto Stele (in Jilin, China). But the legend of Jing?'s invasion of the Korean peninsula also appears in the ancient Japanese chronicles Kojiki written in 680 and Nihon Shoki written in 720.
