Seoul Capital Area
Description
The Seoul Capital Area (SCA) is the metropolitan area of Seoul located in the north-west of South Korea. It is referred to as Sudogwon (Hangul: 수도권; Hanja: 首都圈; RR: Sudogwon; MR: Sudokwŏn, [sʰudoɡwʌn]) or Gyeonggi region (Hangul: 경기 지방; Hanja: 京畿地方; RR: Gyeonggi Jibang; MR: Kyŏnggi Jibang) in Korean, and contains three different administrative districts; Incheon, Seoul and Gyeonggi-do.
The Seoul Capital Area has a population of 24 million (as of 2012)[1] and is ranked as the fourth largest metropolitan area in the world. Its area is about 11,704 km2. It forms the cultural, commercial, financial, industrial, and residential center of South Korea. The largest city is Seoul, with a population of approximately 10 million people, followed by Incheon, with 3 million inhabitants.
Geography and climate
The Capital Area occupies a plain in the Han River valley. It contains some of the most fertile land on the Korean peninsula, although relatively little of it is now used for agriculture. The Gimpo Plain, one of the country's larger expanses of level arable land, covers much of the area of the cities of Gimpo and Bucheon.
History
The Capital Area has been home to a Korean capital for around 2,000 years. Its central location and relatively gentle landscape have given it a central role in the country's affairs.
The first capital to be constructed in the region was that of Baekje, one of the Three Kingdoms of Korea. The country's first capital was built in 19 BC and was named Wiryeseong. This is believed to have been constructed near the modern-day boundary of Seoul and Gwangju City. However, Baekje was unable to hold this territory, and surrendered the Han River valley to Goguryeo in the 5th century. The land was then taken over by Silla in the 6th century, at which point it came to play a critical role in helping Silla to establish ties with China.
After the fall of Silla, Taejo of Goryeo established the capital of his kingdom in Kaesŏng, now just north of the Demilitarized Zone. During the Mongol invasions of Korea in the 12th century, the seat of government briefly shifted to Ganghwa Island, now just south of the DMZ in Incheon metropolitan city, where the Mongol naval attacks were repelled for about a decade before the king voluntarily surrendered to stop the carnage the Mongols committed in the peninsula, in order to lure the king out.
After the fall of Goryeo Dynasty in 1392, the newly founded Joeson Dynasty had its capital (then called Hanseong or Hanyang), less than 100 km south of the old dynasty's capital, Kaesŏng. Hanyang was chosen to be the new capital for mountains surrounding it making it safe from enemies, and for the Han River, separating the north and south parts of the city that let the trade business flourish. During the new dynasty's rule, extensive road systems, administrative buildings, royal palaces, and new ports were built, quickly attracting wealth from all over the kingdom. During the Korean Empire period, Hanseong's public transportation was improved with the installation of streetcars and manually drawn trolleys similar to taxis. Horse carriage systems similar to the ones in Europe were also established.
Following the Japanese annexation of Korea in 1910, Hanseong was renamed Keijo (Gyeongseong) and served as colonial Korea's capital. Upon Korea's liberation from Japan in 1945, the former colonial capital was renamed Seoul and became capital of South Korea.
In the Korean War (1950–1953), the Capital Area became the focus of battles so destructive that most of Seoul and the surrounding regions were eradicated. Seoul was especially hit hard, since it exchanged hands four times during the course of the war.
During the latter half of the 20th century, the Capital Area began to rapidly develop as South Korea's economic wealth expanded. Population expanded fourfold since the Korean War. In 2001, the new Incheon International Airport took over all international flights to Seoul.
Transportation
The cities of the capital area are tightly interconnected by road and rail. Many of the country's railroad lines, most notably the Gyeongbu Line, terminate in the region. In addition, the needs for commuter rail are served by the Seoul Metropolitan Subway, which passes through Seoul, Incheon, and most of the outlying cities.
The region is a nexus for travel by air and water. The country's two largest airports, Incheon International Airport and Gimpo Airport, are in the metropolitan area. International and domestic ferries depart from Incheon's ferry terminals several times a day. Massive volumes of international freight pass through the container terminals of Incheon (primarily bound to and from China).
Seoul Ring Expressway (Expressway No. 100) connects satellite cities around Seoul: Ilsan, Toegyewon, Hanam, Pyeongchon, Songnae, Bundang, Pangyo and Gimpo.
