Early Cold War And Civil Rights Movement Practice Test

Douglas MacArthur served as the commander of UN forces in Korea, holding the role of Supreme Commander for the United Nations Command. When North Korea invaded South Korea in 1950, his leadership guided the early response: he helped organize the defense at the Pusan Perimeter and then crafted the bold Inchon landing, which outflanked the North Koreans, recaptured Seoul, and allowed UN forces to reverse the invasion. This sequence—stubborn defense followed by a decisive counteroffensive—defines why he is remembered as the leader who repelled the North Korean invasion. He remained the top commander until 1951, when he was relieved by President Truman over strategic disagreements. The other figures were prominent in other contexts (World War II or different roles) and did not lead UN forces in Korea.
