Allied forces played a significant role in Black history during various conflicts and wars, particularly in the 20th century. Here are a few key examples:

1. **World War I**: During World War I, Black soldiers from various Allied nations, including the United States, France, and the United Kingdom, fought bravely on the frontlines. The Harlem Hellfighters, officially known as the 369th Infantry Regiment, were an all-Black unit in the U.S. Army that served with distinction and valor in combat in France.

2. **World War II**: Black soldiers and servicemembers from Allied countries played crucial roles in World War II. The Tuskegee Airmen, a group of African American pilots who served in the U.S. Army Air Forces, distinguished themselves with their skill and courage in aerial combat. Additionally, the 761st Tank Battalion, also known as the "Black Panthers," were a Black armored unit that served with distinction in Europe.

3. **Civil Rights Movement**: Black soldiers who fought in Allied forces during wars like World War I and World War II returned home to face ongoing discrimination and segregation in the United States. Many Black veterans became active in the Civil Rights Movement, advocating for equal rights and opportunities for African Americans.

4. **Decolonization and Independence Movements**: In the years following World War II, many African and Caribbean countries fought for independence from their European colonial rulers. Black soldiers who had served in the Allied forces during the war often played key roles in these independence movements, using their military training and experience to fight for freedom and self-determination.

Overall, Allied forces in Black history demonstrate the complex and interconnected nature of racial dynamics, military service, and movements for equality and justice. Black soldiers and servicemembers have contributed significantly to the defense of democracy and freedom while also fighting for their own rights and empowerment.
