What happened to the nation of North Korea after World War 2?

After World War II, Korea was divided along the 38th parallel into two zones of occupation: the Soviet Union controlled the north, while the United States managed the south. In 1948, this division led to the establishment of two separate governments: the Democratic People's Republic of Korea (North Korea) in the north and the Republic of Korea (South Korea) in the south. Tensions escalated, culminating in the Korean War from 1950 to 1953, which solidified the divide and resulted in a heavily militarized border between the two nations. North Korea, under Kim Il-sung, became a communist state with a centralized economy and a focus on military strength.
