Hamhŭng (Hamhŭng-si; Korean pronunciation: [ham. ɦɯŋ]) is North Korea's second largest city, and the capital of South Hamgyŏng Province. In late 2005, nearby Hŭngnam was made a ward (kuyŏk) within Hamhŭng-si.
It has a population of 768,551 as of 2008. Hamhŭng is divided into 7 kuyŏk (wards):Hamhŭng is on the left branch of the Sŏngch'ŏn River, on the eastern part of the Hamhŭng plain (함흥평야), in South Hamgyŏng Province, northeast North Korea. The Tonghŭngsan is 319 m high. Hamhung has a humid continental climate (Köppen climate classification: Dwa), with warm, humid summers, and moderately cold, dry winters. Yi Seong-gye, founder of the Yi Dynasty, retired to the city after a successful palace coup by his son Yi Bang-won in 1400. Though his son sent envoys to reconcile, his father had them killed. A modern Korean expression, 'King's envoy to Hamhŭng' (Hamheungchasa), refers to a person who goes on a journey and is never heard from again. It was known as Kankō during Japanese rule of Korea between 1910 and 1945. It was liberated by the Red Army on 22 August 1945.
