In 940, the founder of Goryeo, King Taejo, changed the city's name to "Gyeongju", which literally means "Congratulatory district". In 987, as Goryeo introduced a system in which three additional capitals were established in politically important provinces outside Gaegyeong (nowadays Kaesong), and Gyeongju was designated as "Donggyeong" ("East Capital"). However, that title was removed in 1012, the third year of King Hyeongjong's reign, due to political rivalries at that time, though Gyeongju was later made the seat of Yeongnam Province. It had jurisdiction over a wide area, including much of central eastern Yeongnam, although this area was greatly reduced in the 13th century. Under the subsequent Joseon (1392–1910) dynasties, Gyeongju was no longer of national importance, but remained a regional center of influence. In 1601, the city ceased to be the provincial capital.
