Daegu (Korean: [tɛɡu], 대구, 大邱, literally 'large hill', 대구광역시), formerly spelled Taegu[a] and officially known as the Daegu Metropolitan City, is a city in South Korea, the fourth-largest after Seoul, Busan and Incheon, the third-largest metropolitan area in the nation with over 2.5 million residents and the second-largest city in Yeongnam after Busan. It was overtaken by Incheon in the 2000s, but still it is said to be the third city according to the "Act on the Establishment of Daegu City and Incheon City" (Act No. 3424 and April 13, 1981). Daegu and surrounding North Gyeongsang Province are often referred to as Daegu-Gyeongbuk, with a total population over 5 million.
Daegu is located in south-eastern Korea about 80 km (50 mi) from the seacoast, near the Geumho River and its mainstream, Nakdong River in Gyeongsang-do. 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 Dynasty period, the city was the capital of Gyeongsang-do, one of the traditional eight provinces of the country.
Daegu was an economic motor of Korea during the 1960s–1980s period and was especially known for its electronics industry. The humid subtropical climate of Daegu is ideal for producing high-quality apples, thus the nickname, "Apple City". Daegu is also known as "Textile City". Textiles used to be the pillar industry of the city. With the establishment of the Daegu-Gyeongbuk Free Economic Zone, Daegu is currently focusing on fostering fashion and high-tech industries.
