Military Demarcation Line in the context of "Demarcation line"

The division of Korea began at the end of World War II on 2 September 1945, with the establishment of a Soviet occupation zone and a US occupation zone. These zones developed into separate governments, named the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea), which fought a war from 1950 to 1953. Since then the division has continued.

By the early 20th century, both countries were one single nation: the Korean Empire. During World War II, the Allied leaders had already been considering the question of Korea's future following Japan's eventual surrender in the war. The leaders reached an understanding that Korea would be removed from Japanese control but would be placed under an international trusteeship until the Koreans would be deemed ready for self-rule. In the last days of the war, the United States proposed dividing the Korean peninsula into two occupation zones (a U.S. and Soviet one) with the 38th parallel as the dividing line. The Soviets accepted their proposal and agreed to divide Korea, which led to the declaration of General Order No. 1.

Kaesong (UK: /keɪˈsɒŋ/, US: /keɪˈsɔːŋ/; Korean: [kɛsʌ̹ŋ]) is a special city in the southern part of North Korea (formerly in North Hwanghae Province), and the capital of Korea during the Taebong kingdom and subsequent Goryeo dynasty. The city is near the Kaesong Industrial Region close to the border with South Korea and contains the remains of the Manwoldae palace. Called Songdo while it was the ancient capital of Goryeo, the city prospered as a trade centre that produced Korean ginseng. Kaesong now functions as North Korea's light industry centre.

During the Japanese occupation from 1910 to 1945, the city was known by the Japanese pronunciation of its name, "Kaijō". Between 1945 and 1950, Kaesong was part of South Korea and under its control. During the Korean War, North Korea captured the city, and the 1953 Korean Armistice Agreement left the city under North Korean control. Due to the city's proximity to the border with South Korea, Kaesong has hosted cross-border economic exchanges between the two countries as well as the jointly run Kaesong Industrial Region.

Gangwon Province (Korean: 강원도; RR: Gangwon-do), officially Gangwon State (강원특별자치도; lit. Gangwon Special Self-Governing Province), is a Special Self-Governing Province of South Korea. It is known as the largest and least densely populated subdivision of South Korea. Gangwon is one of the three provinces in South Korea with special self-governing status, the others being Jeju Province and Jeonbuk State. Gangwon is bordered on the east by the East Sea(Or Sea of Japan), it borders Gyeonggi Province to the west, North Gyeongsang Province and North Chungcheong Province to the south, and the Military Demarcation Line to the north, separating it from North Korea. In the 1945 division of Korea, the historical Gangwon Province was divided in half, and remains so to this day.

Pyeongchang County in Gangwon hosted the 2018 Winter Olympics and 2018 Winter Paralympics. Gangwon also hosted the 2024 Winter Youth Olympics.
