evidence: 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. [...] Finally, the new provinces of Jeju Province (in the south, in 1946) and Chagang Province (in the north, 1949) were formed, from parts of South Jeolla and North Pyongan respectively. In 1954, Ryanggang Province was split from South Hamgyong and Hwanghae was divided into North and South Hwanghae Provinces. [...] - ^ "Gwandong" is the name for the region as a whole, with "Yeongseo" denoting the western half of the province and "Yeongdong" the eastern half. "Yeongdong" is used more often than either of the other two terms, however, especially in reference to railway and road arteries that cross through Gangwon, connecting the Seoul and Yeongdong regions.
