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, many Black soldiers served in segregated units in the United States military, as racism and discrimination persisted. Despite facing discrimination, these soldiers demonstrated great bravery and heroism on the battlefield. One of the most well-known units was the 369th Infantry Regiment, also known as the "Harlem Hellfighters," which spent more time in combat than any other American unit during the war.

In World War II, African Americans again faced segregation and discrimination in the military. However, their contributions were instrumental in helping the Allies achieve victory. The Tuskegee Airmen, an all-Black squadron of pilots who fought in the skies over Europe, became legendary for their skill and bravery. The "Double V" campaign, which called for victory over fascism abroad and racism at home, became a rallying cry for the civil rights movement.

Both World Wars played a significant role in shaping the fight for civil rights in the United States. The experiences of Black soldiers during these conflicts highlighted the contradictions between fighting for freedom and democracy abroad while facing racism and injustice at home. These experiences helped to fuel the burgeoning civil rights movement in the post-war years.
