African American soldiers played a crucial role in the Civil War, contributing significantly to the Union Army once recruitment for Black troops began in 1863. Approximately 180,000 African Americans served in the Union forces, demonstrating their commitment to the fight against slavery and for their rights. They engaged in numerous battles, including notable ones like Fort Wagner, and faced discrimination and harsher conditions compared to white soldiers, often receiving lower pay. Their service helped reshape the perception of Black Americans' capabilities and valor, paving the way for the eventual integration of the U.S. military and significantly contributing to the Union's victory.
