On July 26, 1948, President Harry S. Truman signed Executive Order 9981, declaring equality of treatment and opportunity for all persons in the armed forces regardless of race, color, religion, or national origin. Issued under sustained pressure from civil rights leader A. Philip Randolph, who threatened a Black draft resistance campaign, the order dismantled the racially segregated military that had fought World War II. Full implementation took until the Korean War. It was the most significant federal civil rights action since Reconstruction and set the precedent for broader desegregation.
