Answer:
The 14th Amendment to the U.S. Constitution, ratified in 1868, granted citizenship to all persons born or naturalized in the United States—including former slaves—and guaranteed all citizens “equal protection of the laws.” One of three amendments passed during the Reconstruction era to abolish slavery and establish civil and legal rights for black Americans, it would become the basis for many landmark Supreme Court decisions over the years. The opening sentence of Section 1 of the 14th Amendment defined U.S. citizenship: “All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”
This clearly repudiated the Supreme Court’s notorious 1857 Dred Scott decision, in which Chief Justice Roger Taney wrote that a black man, even if born free, could not claim rights of citizenship under the federal constitution.
Section 1’s next clause was: “No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States.” This greatly expanded the civil and legal rights of all American citizens by protecting them from infringement by the states as well as by the federal government.
The third clause, “nor shall any State deprive any person of life, liberty or property, without due process of law,” expanded the due process clause of the Fifth Amendment to apply to the states as well as the federal government.
Over time, the Supreme Court has interpreted this clause to guarantee a wide array of rights against infringement by the states, including those enumerated in the Bill of Rights (freedom of speech, free exercise of religion, right to bear arms, etc.) as well as the right to privacy and other fundamental rights not mentioned elsewhere in the Constitution.
Finally, the “equal protection clause” (“nor deny to any person within its jurisdiction the equal protection of the laws”) was clearly intended to stop state governments from discriminating against black Americans, and over the years would play a key role in many landmark civil rights cases.
14TH AMENDMENT – SECTIONS 2-5
In its later sections, the 14th Amendment authorized the federal government to punish states that violated or abridged their citizens’ right to vote by proportionally reducing the states’ representation in Congress, and mandated that anyone who “engaged in insurrection” against the United States could not hold civil, military or elected office (without the approval of two-thirds of the House and Senate).
It also upheld the national debt, but exempted federal and state governments from paying any debts incurred by the former Confederate states.
The fifth and final section of the 14th Amendment (“Congress shall have the power to enforce, by appropriate legislation, the provisions of this article”) echoed a similar enforcement clause in the 13th Amendment.
In giving Congress power to pass laws to safeguard the sweeping provisions of Section 1, in particular, the 14th Amendment effectively altered the balance of power between the federal and state governments in the United States.
Nearly a century later, Congress would use this authority to pass landmark civil rights legislation, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
In 1867, the Republican-dominated Congress passed the First Reconstruction Act, over President Andrew Johnson’s veto, dividing the South into five military districts and outlining how new governments based on universal manhood suffrage were to be established. With the adoption of the 15th Amendment in 1870, a politically mobilized African American community joined with white allies in the Southern states to elect the Republican Party to power, which brought about radical changes across the South. By late 1870, all the former Confederate states had been readmitted to the Union, and most were controlled by the Republican Party, thanks to the support of African American voters.
In the same year, Hiram Rhodes Revels, a Republican from Natchez, Mississippi, became the first African American ever to sit in Congress. Although African American Republicans never obtained political office in proportion to their overwhelming electoral majority, Revels and a dozen other African American men served in Congress during Reconstruction, more than 600 served in state legislatures, and many more held local offices. However, in the late 1870s, the Southern Republican Party vanished with the end of Reconstruction, and Southern state governments effectively nullified the 14th and 15th Amendments, stripping Southern African Americans of the right to vote. It would be nearly a century before the nation would again attempt to establish equal rights for African Americans in the South.
