Provinces of Korea - Historical Summary

Historical Summary

During the Unified Silla Period (AD 668–935), Korea was divided into nine Ju (주; 州), an old word for "province" that was used to name both the kingdom's provinces and its provincial capitals. (see also: Zhou (country subdivision))

After Goryeo defeated Silla and Later Baekje in 935 and 936 respectively, the new kingdom "was divided into one royal district (Ginae; 기내; 畿內) and twelve administrative districts (Mok; 목; 牧)" (Nahm 1988), which were soon redivided into ten provinces (Do). In 1009 the country was again redivided, this time into one royal district, five provinces (Do) and two frontier districts (Gye; 계; 界?). The name and concept of Do originated from the Chinese Dao.

After the Joseon Dynasty's rise to power and the formation of Joseon in 1392, the country was redivided into eight new provinces (Do) in 1413. The provincial boundaries closely reflected major regional and dialect boundaries, and are still often referred to in Korean today simply as the Eight Provinces (Paldo). In 1895, as part of the Gabo Reform, the country was redivided into 23 districts (Bu; 부; 府), which were replaced a year later by thirteen new provinces.

The thirteen provinces of 1896 included three of the original eight provinces, with the five remaining original provinces divided into north and south halves (Bukdo (북도; 北道) and Namdo (남도; 南道) respectively). The thirteen provinces remained unchanged throughout the Japanese Colonial Period.

With the surrender of Japan in 1945, the Korean peninsula was divided into Soviet (northern) and American (southern) zones of occupation, with the dividing line established along the 38th parallel. (See Division of Korea for more details.) As a result, three provinces—Hwanghae, Gyeonggi, and Gangwon (Kangwŏn)—were divided into Soviet- and American-occupied sections.

The special cities of Seoul and P'yŏngyang were formed in 1946. Between 1946 and 1954, five new provinces were created: Jeju in South Korea, and North and South Hwanghae, Chagang, and Ryanggang in North Korea.

Since 1954, provincial boundaries in both the North and South have remained unchanged. New cities and special administrative regions have been created, however: see Special cities of Korea for their history.
