North and South Korea are divided by the -

The division of Korea or the partition of Korea began at the end of World War II on 2 September 1945, with the establishment of a Soviet occupation zone in the north and a US occupation zone in the south. 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 18th century, both countries were one single nation: the Korean Empire, only to be annexed by the Empire of Japan in 1910. 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 colonial 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.
