History


Prehistory

There is evidence of human habitation in the area now corresponding to Seoul from 30,000 to 40,000 years before the present. Around 4,000 B.C., people of the area lived in huts with lowered floors called '' umjip''. There is evidence of the consumption of cooked grain and fish by 3,000 B.C.

took the control of the region from Baekje, and the city became a part of newly established Sin Province (). Sin (新) has both meaning of "New" and "Silla", thus literally means New Silla Province. In November 555, Jinheung Taewang made a royal visit to Bukhansan, and inspected the frontier. In 557, Silla abolished Sin Province, and established Bukhansan Province (). The word Hanseong () appears on the stone wall of "Pyongyang Fortress", which was presumably built in the mid to late 6th century AD over period of 42 years, located in Pyongyang, while there is no evidence that Seoul had name Hanseong dating the three kingdoms and earlier period. In 568, Jinheung Taewang made another royal visit to the northern border, visited Hanseong, and stayed in Namcheon on his way back to the capital. During his stay, he set Jinheung Taewang Stele, abolished Bukhansan Province, and established Namcheon Province (), appointing the city as the provincial capital. Based on the naming system, the actual name of Han River during this time was likely Namcheon (Nam River) itself or should have the word ending with "cheon" () not "gang" () nor "su" (). In addition, "Bukhansan" Jinheung Stele clearly states that Silla had possession of Hanseong (modern day

The ''Doseong-an'' area later gained the informal but popular name ''Seodaemun-an'' (), which literally means 'areas inside of the Four Great Gates', and became the one and only downtown (city center) of Hanyang city.

Contemporary history

In 1945, following the liberation from Japanese colonial rule, the American military assumed control of Korea, including its capital city, then referred to as Kyeongseongbu in line with Japanese nomenclature. The U.S. military government published the Charter of the City of Seoul in the official gazette on October 10 of the following year. The charter declared Seoul as the name of the city and established it as a
municipal corporation Municipal corporation is the legal term for a local governing body, including (but not necessarily limited to) cities, counties, towns, townships, charter townships, villages, and boroughs. The term can also be used to describe municipally o ...
. Seoul's status as a municipal corporation mirrored the independent cities in the United States that do not belong to any county, and Seoul was established as an independent administrative unit, separate from the existing provinces. The Korean version of the Charter translated "''municipal corporation''" as "''special free city''" (), which later became special metropolitan city (or special metropolitan city; ) in the . Seoul has retained its status as the only special metropolitan city in South Korea. Seoul under the U.S. military government between 1945 and 1948 was much smaller than it is today. It only covered the Fortress Wall, marked by the Eight Gates, and the districts incorporated during Japanese rule to prosecute imperial Japan's war efforts. During the

In addition, a flood of refugees had entered Seoul during the war, swelling the population of the city and its metropolitan area to an estimated 1.5 million by 1955. Following the war, Seoul began to focus on reconstruction and modernization. As South Korea's economy started to grow rapidly from the 1960s,

In July 2020, South Korea, then the 11th largest world economy, announced a US$35 billion position on ending investment in coal. In November 2020, South Korea committed to a carbon-neutral economy by 2050. Between 2005 and 2021 annual concentration levels of small particulate matter (PM10) fell by 30-40 % in Seoul, whilst concentrations of larger particulate matter (PM 2.5) in the same period fell by 19% across the country and more in Seoul and Gyeonggi. Asian dust, emissions from Seoul and in general from the rest of South Korea, as well as emissions from China, all contribute to Seoul's air quality. Besides air quality, greenhouse gas emissions represent hot issues in South Korea since the country is among top-10 strongest emitters in the world. Seoul is the strongest hotspot of greenhouse gas emissions in the country and according to satellite data, the persistent carbon dioxide anomaly over the city is one of the strongest in the world. Air quality is monitored by geo-stationary satellite measurements centred on Korea and its immediate neighbours.

The target was to cut pollution to over 30% below the legal limit of 50 μg/m3. It was 32 μg/m3 by 2026. The outset actuality was 38.8 μg/m3 average concentration of pollution.  Starting in 2024, ₩100 billion annually for three years was earmarked for air pollution reduction measures. These included installation of air conditioning, better ventilation systems and filters, replacement of dust-inducing gravel rail tunnel beds with concrete ones, dust-capture matting at turnstiles, and constant public readings for pollution within the system.
