Korea (Korean: 한국; RR: Hanguk in South Korea, or Korean: 조선; MR: Chosŏn in North Korea) is a peninsular region in East Asia consisting of the Korean Peninsula (한반도; 韓半島; Hanbando in South Korea, or 조선반도; 朝鮮半島; Chosŏnbando in North Korea), Jeju Island, and smaller islands. Since the end of World War II in 1945, it has been politically divided at or near the 38th parallel between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK). Both countries proclaimed independence in 1948, and the two countries fought the Korean War from 1950 to 1953.
