Q & A

What was the main cause of the Korean War?

Both zones became independent states with opposing ideologies, leading to conflict.

How did Japan's control of Korea prior to World War II influence the situation leading up to the Korean War?

Japan had controlled Korea from 1910 to 1945. After World War II, Japan withdrew, and Korea was liberated and divided into two zones. This division set the stage for the later conflict as both the North and South claimed to be the legitimate government of all Korea.
