Why Harry Truman Ended Segregation in the US Military in 1948

On July 26, 1948, President Harry S. Truman signed Executive Order 9981, mandating the desegregation of the U.S. Armed Forces and ending 170 years of officially sanctioned racial discrimination in the military. Although African Americans had served since the Revolutionary War, they were typically segregated from white troops and often assigned to menial roles. A landmark achievement of both the postwar civil rights movement and Truman’s presidency, the order marked one of the first times a U.S. president used executive authority to advance civil rights. It also helped pave the way for broader desegregation efforts across American society.
