The Declaration of Independence announced equality as an American ideal, but it took the Civil War and the subsequent adoption of three constitutional amendments to establish that ideal as American law. The Reconstruction amendments abolished slavery, guaranteed all persons due process and equal protection of the law, and equipped black men with the right to vote. They established the principle of birthright citizenship and guaranteed the privileges and immunities of all citizens. The federal government, not the states, was charged with enforcement, reversing the priority of the original Constitution and the Bill of Rights. In grafting the principle of equality onto the Constitution, these revolutionary changes marked the second founding of the United States. Author: Eric Foner. Hardcover; 256 pages.
