Which US President ended segregation in the US Armed Forces?

Harry S. Truman is the U.S. President who ended segregation in the Armed Forces through Executive Order 9981, issued on July 26, 1948. This landmark order declared that it was the policy of the United States to provide equal opportunity in the military regardless of race, color, religion, or national origin. Truman's action marked a significant step toward civil rights by addressing racial discrimination within the military, ultimately leading to the desegregation of all branches over the following years.

The decision was born out of several factors, including the changing social dynamics after World War II, the pressure from civil rights advocates, and the need to create a unified and effective military. By taking this step, Truman not only transformed the U.S. Armed Forces but also laid the groundwork for further civil rights initiatives across the country in subsequent decades.
