In 1945, Kangwŏn Province (along with the rest of Korea) was divided by the 38th parallel north in 1945 into Soviet and American zones of occupation in the north and south respectively. In 1946, the northern province was expanded to include the North Korean portion of Gyeonggi Province and the area around Wŏnsan in South Hamgyŏng Province. The provincial capital of the North Korean portion of the province was established at Wŏnsan, as Kangwŏn's traditional capitals Wonju and Chuncheon both were south of the 38th parallel.
