African Americans gained rights during the beginning of Reconstruction, however they would be taken away by a series of laws passed by state governments. For example, African American men gained the right to vote with the passing of the 15th amendment. However, by the end of the Reconstruction era, many African American men were not allowed to vote. This was through the creation of poll taxes, literacy tests, and the grandfather clause. These laws limited participation in voting from African American men.
