of the Wanli Emperor's "Three Great Punitive Campaigns". Contemporary Chinese historians often use the campaigns as an example of the friendship that China and Korea shared. In Korea, the war is a historic foundation of Korean nationalism and, as in China, inspired and politically used to instigate nationalistic resistance against Japanese imperialism during the 20th century. Korea gained several national heroes during the conflict, including Yi Sun-sin and Chen Lin (founder of the Gwangdong Jin clan). Modern anti-Japanese sentiment in Korea can be traced as far back as the Japanese invasions in 1592, although the principal cause is rooted in more recent events, particularly the hardships suffered by Koreans during the Japanese occupation of Korea from 1910 through 1945. The widespread guerilla warfare fought by various righteous armies, which spearheaded the Korean civilian resistance against the Japanese invasion, had a significant impact on the common Korean populace's conceptions of nationhood and identity. The invasions and subsequent efforts by the local gentry to rally the commoners had a critical impact on perceptions of national identity in Korea, as the gentry were recorded to have sent many letters and declarations against the Japanese invaders and called upon shared Korean history, culture and beliefs to unite the Korean people. International awareness Despite great interest in the war in East Asia, the Japanese invasions of Korea are not widely known in the West. Many history textbooks treat the war with only a few lines of mention, and with the exception of Samurai Invasion: Japan's Korean War 1592–98 (2002) by Turnbull, no complete academic studies on the subject exist in English, although both James Murdoch and George Sansom covered the topic in some detail in their general historical surveys of Japan, A History of Japan (1903) and A History of Japan (1958), respectively. Henry Kissinger mentions the conflict in World Order (2014).
