When Japan took over Taiwan in 1895, a lot of Taiwanese defendedtheir home in a body of "Yi-Ming" (義民righteous people)-a collective civil armed corps. This war was called "Yi-Wei War" (乙未戰爭) which was the biggest scale war that ever occurred at Taiwan territory within the memory of men. Generally, there were two kinds historical standpoints about the Yi-Wei war, one was the viewpoint from the Great China, the other was that from Taiwan. With one consent, the two viewpoints always discussed the war from the beginning of war between the Chin-Japan occurred in 1894 called "Zia-Wu War" (甲午戰爭). What the difference was that the former always narrated the story based on the viewpoint of Great China nationalism, the latter attempted to establish the viewpoint of Taiwan nationalism. Undoubtedly, the two discourses seriously ignored the self-determination of Taiwanese for example the emergency of the Republic of Taiwan, and the ethnical diversities in Taiwan for example the Hakka. The discussions in this article is based on the viewpoint of grassroots and referred to the analytic framework of Fernand Braudel, which we named it the historical standpoint of Yi-Ming. That is, only if should we realize the whys and wherefores of the "Yi-Ming" (righteous people) arose since 1721, we could not touch the truth of the "Yi-Wei War" (乙未戰爭).
