Why did the Korean War happen?

The Korean War was a conflict that lasted from 1950 to 1953 and involved the two Koreas, North and South Korea. The war was a result of the Cold War tensions between the United States and the Soviet Union, as well as the post-World War II division of Korea into two separate states. In 1945, Korea was divided into a Soviet-backed communist government in the North and a U.S.-backed democratic government in the South.

On June 25, 1950, North Korea invaded South Korea with the support of the Soviet Union and China. The United States and other countries, under the United Nations flag, intervened in the war to support South Korea. The conflict ended in a stalemate and the signing of an armistice agreement on July 27, 1953.

The Korean War had far-reaching consequences, as it intensified Cold War tensions and led to a strengthened U.S. military presence in the region. It also resulted in the death of millions of Koreans and the continued division of Korea into two separate states.
