Gyeongsang Province was Jinhan and Byeonhan's territory in ancient times. Later Jinhan became Gaya and Byeonhan became Silla. Since Silla conquered Gaya, all of Gyeongsang Province became Silla's. When Silla collapsed and Goryeo was founded, Dongnambuseosa was established in the Gyeongsang area and it ruled the province. From Goryeo King Hyeonjong's period, the province started to be called Gyeongsang Province. In the Joseon Dynasty, which was founded after Goryeo, Gyeongsang Province was divided into Left Gyeongsang and Right Gyeongsang. In 1895, Gyeongsang Province was replaced by 4 districts. Later, in 1896, the districts were abolished, and today's North Gyeongsang and South Gyeongsang were formed. In 1981 Daegu Metropolitan City separated from the province.
