Through South Korea, Planned community and Smart city

Sejong was founded in 2007 as the new planned capital of South Korea created mostly from parts of South Chungcheong Province and some parts of North Chungcheong Province in order to ease congestion in South Korea's current capital and largest city, Seoul, and to encourage investment in the country's central region. Since 2012, the government of South Korea has relocated numerous ministries and agencies to Sejong, but many still reside in other cities, primarily in Seoul, where the National Assembly and many important government bodies remain.

Sejong has a population of 351,007 as of 2020 and covers a geographic area of 465.23 km2 (179.63 sq mi), making it the least-populous and smallest first-level administrative division in South Korea. Sejong is located in the west-central Hoseo region, bordering South Chungcheong to the west, Daejeon to the south, and North Chungcheong to the east.

The construction of the city is expected to be completed in 2030, at which time 500,000 people are expected to live there.

Name

Sejong was named in honor of King Sejong the Great, the fourth king of the Joseon Dynasty and creator of the Korean alphabet, Hangul. The city was formed by combining Yeongi County, the county of South Chungcheong Province from which the majority of the city's territory was ceded, and other counties.
