World War I and World War II had significant impacts on Black history. During World War I, many Black Americans served in segregated units in the United States military, facing discrimination and unequal treatment both at home and abroad. Despite their bravery and sacrifices, many Black soldiers returned home to continued racism and discrimination.

In World War II, the involvement of Black Americans in the war effort played a crucial role in the fight against fascism, both on the battlefield and on the home front. The "Double V" campaign emerged during this time, calling for victory over fascism abroad and victory over racism at home. Black soldiers faced segregation and discrimination in the military, but their service helped pave the way for the eventual desegregation of the armed forces in 1948.

The contributions of Black soldiers in various roles throughout both World Wars helped challenge racial stereotypes and pave the way for the civil rights movement in the United States. The experiences of Black servicemen and women during these wars highlight the ongoing struggle for equality and justice that has been a central part of Black history.
