갑신정변
Conflict between the conservative court and a reforming faction led to the Gapsin Coup in 1884. The reformers sought to reform Korea's institutionalized social inequality, by proclaiming social equality and the elimination of the privileges of the yangban class. The reformers were backed by Japan, and were thwarted by the arrival of Qing troops, invited by the conservative Queen Min. The Chinese troops departed but the leading general Yuan Shikai remained in Korea from 1885-1894 as Resident, directing Korean affairs.
