evidence: Korea has had administrative districts that can be considered provinces since the 7th century. These divisions were initially called ju (Korean: 주; Hanja: 州) in Unified Silla and Later Baekje, and there were nine in total. After Goryeo conquered these states in the 10th century, twelve divisions called mok (목; 牧) were established, although they were reorganized into ten do (도; 道) in the 11th century. [...] With the liberation of Korea in 1945, the Korean peninsula was divided into North Korea and South Korea, with the dividing line established along the 38th parallel. As a result, three provinces—Hwanghae, Gyeonggi, and Gangwon (Kangwŏn)—were divided into North Korea and South Korea in today's era. The special cities of Seoul (South Korea) and P'yŏngyang (North Korea) 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 but new cities and special administrative regions have been created. [...] Provincial divisions since the division of Korea [edit]At the end of World War II in 1945, Korea was divided into Northern Korea and Southern Korea under trusteeship of the Soviet Union and the United States. The peninsula was divided at the 38th parallel in 1945. In 1948, the two zones became the independent countries of North Korea and South Korea.
