Yakpo Jeongtak was a man who actively engaged in military and political activities for the country during the Imjin War. Due to his great exploits, the prior studies mainly dealt with war strategies or tactics. The study on his activities was done in ideological aspect due to the status of Toegye, Nammyeong's disciple and the works that showed and Neo-Confucian study. But many of the war poetry he left behind were relatively not enlightened, and only a few of his works were used in analysis of the world of his poetry. Thus, In this paper, we took a look at the perception of the age of Yakpo, which looked at the Imjin War, focusing on his war poetry of his collection of works, the book named ‘Yakpojip’(the collection of Jeongtak) and records he left behind. He was objectively recognized the situation of the Imjin War, which was characterized as an international war, and how great the participation of the Ming soldiers and their combined operations played a significant role in the Imjin War. He expressed strong opposition to the peace treaty with Japan and secretly expressed his dissatisfaction with Ming, who eventually reached a negotiated settlement and retreated, but as a farewell envoy, he listened to their demands and wrote poetries praising their exploits. Yakpo, the chief policy maker and implementer of the Joseon Dynasty, identified the situation of Ming soldiers and responded to the international situation. His poetries were sensitive to diplomatic relations centered on the Ming, unlike other war poetries of the same time. It is hoped that such research, which combines the war poetry with the perception of war by a person, will contribute to the study of military history in the future from the perspective of a combination of "literature" and "war" instead of the existing study of literary history that focused on individuals.
