Who were the historical people involved in the Korean War and what was their role?

The Korean War (1950-1953) involved key historical figures such as U.S. President Harry S. Truman, who authorized military intervention to support South Korea; General Douglas MacArthur, who led UN forces during the conflict; and North Korean leader Kim Il-sung, who initiated the war by invading South Korea. Additionally, Chinese Communist leader Mao Zedong played a significant role by sending troops to support North Korea. These leaders shaped the strategies and outcomes of the war, which ultimately ended in a stalemate and an armistice agreement.
