Gyeonggi

Gyeonggi Province (, kjʌ̹ŋ.ɡi.do̞) is the most populous province in South Korea. Seoul, the nation's largest city and capital, is in the heart of the area but has been separately administered as a provincial-level special city since 1946. Incheon, the nation's third-largest city, is on the coast of the province and has been similarly administered as a provincial-level metropolitan city since 1981. The three jurisdictions are collectively referred to as Sudogwon and cover , with a combined population of over 26 million - amounting to over half (50.25%) of the entire population of South Korea at the 2020 Census. Its name, Gyeonggi, means "京 (the capital) and 畿 (the surrounding area)". Thus, Gyeonggi-do can be translated as "Seoul and the surrounding areas of Seoul". Gyeonggi-do has been a politically important area since 18 BCE, when Korea was divided into three nations during the Three Kingdoms period. Ever since King Onjo, the founder of Baekje (one of the three kingdoms), founded the government in Wiryeseong of Hanam, the Han River Valley was absorbed into Goguryeo in the mid-fifth century, and became Silla's territory in the year 553 (the 14th year of King Jinheung). Afterward, the current location of Gyeonggi-do, one of the nine states of Later Silla, was called Hansanju. The Gyeonggi region started to rise as the central region of Goryeo as King Taejo of Goryeo (the kingdom following Silla) set up the capital in Gaesong. Since 1018 (the 9th year of Goryeo's King Hyeonjong), this area has been officially called "Gyeonggi". During the Joseon, which was founded after the Goryeo, King Taejo of Joseon set the capital in Hanyang, while restructuring Gyeonggi's area to include Gwangju, Suwon, Yeoju, and Anseong, along with the southeast region. Since the period of King Taejong and Sejong the Great, the Gyeonggi region has been very similar to the current administrative area of Gyeonggi-do. In 1895 the 23-Bu system, which reorganized administrative areas, was effected.
