Answer:
I can tell you that the presence of African American soldiers during the U.S. Civil War had a significant impact on racial bigotry during the post-Civil War era.
Step-by-step explanation:
The bravery and sacrifice of African American soldiers helped to challenge racial stereotypes and prejudice. Many white Americans had assumed that African Americans were cowardly and weak, and were not capable of fighting in battle. However, the service of African American soldiers during the Civil War proved that they were just as brave and capable as any other soldiers. This helped to challenge the deeply ingrained racial prejudices of many white Americans.
African American soldiers played a key role in securing victory for the Union, which helped to shift the balance of power in favor of the federal government. This gave the federal government more power to enforce civil rights laws and protect the rights of African Americans. The presence of African American soldiers also helped to inspire other African Americans to demand equal rights and to fight for their freedom and equality.
