History of Wonsan

Provincial borders

Wŏnsan used to be in South Hamgyong, but when provincial borders were redrawn in 1946, it joined the northern half of Kangwŏn (which had been split at the 38th parallel north into a zone under Soviet control in the north and one of American control in the south in 1945) and became its capital, as Kangwŏn's traditional capitals Wonju (1395–1895) and Chuncheon (since 1896) both were south of the 38th parallel and south of the Military Demarcation Line that replaced the 38th parallel as a border in 1953. It was heavily bombed by the United Nations during the Korean War's Blockade of Wonsan. In fact, according to the official US Navy history, Wŏnsan was under continuous siege and bombardment by the American navy from March 1951 until July 27, 1953, making it the longest siege in modern American naval history. By war's end the city was a vast shell.

Wŏnsan serves as the administrative center of Kangwŏn Province
