During the Japanese rule, Keijō Imperial University was established as one of Japan’s nine imperial universities. After World War II and the independence of Korea, the name of the university was changed from Keijō Teikoku Daigaku (京城帝国大学) to Gyeongseong Daehak (경성대학, 京城大學, Gyeongseong University). The Hanja letters, that were used in the name, were pronounced in the Korean reading and the attribute “Imperial” was removed. The renaming of “National” was based on the academic nationalism supported by the US military regime[clarification needed] in Korea at the time.
