Daegu (Korean: 대구 [tɛ̝.ɡu]), formerly spelled Taegu and officially Daegu Metropolitan City (대구광역시), is a city in southeastern South Korea. It is the third-largest urban agglomeration in South Korea after Seoul and Busan; the fourth-largest metropolitan city in the nation with over 2.3 million residents; and the second-largest city after Busan in the Yeongnam region in southeastern South Korea. Daegu and the surrounding North Gyeongsang Province are often referred to as Daegu-Gyeongbuk, with a total population of over 5 million.
Daegu is located in south-eastern Korea about 80 km (50 mi) from the coast, near the Geumho River and its mainstream, Nakdong River in Gyeongsang Province. The Daegu basin is the central plain of the Yeongnam region. In ancient times, the Daegu area was part of the proto-kingdom Jinhan. Subsequently, Daegu came under the control of the Silla Kingdom, which unified the Korean Peninsula. During the Joseon period, the city was the capital of Gyeongsang Province, one of the traditional eight provinces of the country.
