Dongdaemun District was first created in 1943 when the "gu" system started and was larger in area than it is today. Seongbuk District separated from the district in 1949, and Changsin Dong and Sungin Dong were given to Jongno District in 1975. An additional 17 "dong" (neighborhoods) separated to become Jungnang District in 1988.
