忠武公 鄭忠信의 生涯와 現實認識

Abstract

This study aims to examine the life and thought of governance of Chungmugong Jeong Chung shin, who served as a commander in the northwest before and after Lee Gwal's rebellion and Manchu Invasion of Joseon (Korea) in 1627 in the early 17th century. For this purpose, this study broadly divides his life into growth education and going to office participation under the leadership of Gwangjumoksa Kwon Yul, and above all, examines the process of meeting Baeksa Lee Hang bok, who was a National Defense vassal at the time in 1592, and the situation of pursuing his studies through him. And, after going to office, he played a key role in the battle of Ahnhyeon, a decisive moment to level Lee Gwal's rebellion, and this study examines in particular, after the Manchu Invasion of Joseon, his realistic responses opposite to the ignorant decision of the royal court and vassals, consistent with justification and cause. Through this, the reason why he did not participate in Lee Gwal’s rebellion, the tactical judgment of the enemy's tactics, and the analysis of the situation that the demand for Jusen's annual tribute was not the object of ‘braking off amity (絶和)’ confirm the fact that he consistently maintained a practical attitude. In particular, in discussing military work, it is demonstrated that defense policies, such as effective military supply and demand measures to build fortresses through cooperation between regions and to carry out fortress defense battles, and the installation of beach encampment, were implemented with a focus on practicality based on the insights and perspectives of field practitioners.
