The Korean War was a conflict that took place from 1950 to 1953 between North Korea and South Korea. It began on June 25, 1950, when North Korea invaded South Korea, which was backed by the United States and other United Nations countries.

The war was fought by both sides with the help of their respective allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United States and other Western countries.

The war was characterized by intense fighting, with both sides suffering significant casualties. The war ended on July 27, 1953, with the signing of an armistice agreement that established a demilitarized zone (DMZ) along the 38th parallel, which was the original border between North and South Korea.

The Korean War had far-reaching consequences for both North and South Korea. The North Korean economy was severely impacted by the war, and the country became increasingly isolated from the rest of the world. Meanwhile, South Korea experienced rapid economic growth in the post-war period, becoming one of the world's leading economies.

In conclusion, the Korean War was a significant event in the history of the Korean Peninsula and the world. Its legacy continues to be felt today, with the ongoing tensions between North and South Korea, and the role of the United States in the region.
