The Reconstruction Era after the Civil War aimed to resolve how the Confederate states would rejoin the Union and address the civil rights of newly freed slaves. Some key accomplishments included the 13th Amendment abolishing slavery, the 14th Amendment granting citizenship and equal protection under the law, and the 15th Amendment giving black men the right to vote. However, the Reconstruction Era was also met with resistance through black codes and efforts to strip black people of political and civil rights gained during Reconstruction.
