World War I and World War II were significant events in Black history as African Americans played crucial roles in both conflicts. During World War I, over 350,000 Black soldiers served in segregated units in the U.S. military. Despite facing discrimination and prejudice, many Black soldiers distinguished themselves in battle and contributed to the Allied victory.

During World War II, over one million African Americans served in the U.S. military, with many being assigned to support roles due to segregation policies. The Tuskegee Airmen, an all-Black squadron of pilots, gained renown for their skill and bravery in combat. Additionally, the contributions of Black women during the war effort, particularly in the defense industry and as nurses, were vital to the war effort.

These wars were transformative experiences for many African Americans, as they fought for freedom and democracy overseas while also confronting systemic racism and segregation at home. The recognition of their contributions to the war efforts played a role in the burgeoning Civil Rights Movement that followed in the decades after World War II.
