How did slaves dress before the US Civil War?
They would have been dressed in rough cotton or linen material with little shape to them. Most would have been barefoot. Slaves that worked in the house would have had full outfits, of a better material and would even have shoes.
What is the Difference between immigrants who came to the US before the civil war and those who came after the civil war?
Before, during and after the US Civil War the civil rights of freed slaves and free Afro Americans were severely restricted. Some States before the Civil War would not even allow freed slaves to enter their States. Rights of voting, marriage, holding certain jobs and other normal civil rights of the white majorities were not always the same as for freed slaves.
