African Americans did all they could to help the Union army. This was especially true after the Emancipation Proclamation, as Lincoln attempted to free slaves from the control of Confederate states. This was one of the many reasons why African Americans in the South helped Union forces.
I'm assuming they both where a ancient native american cultures but both have industrious and neither had written records of their cultures. Hope This Helps?
