1. Before the Civil War ended, Congress passed the 13th Amendment to the Constitution, which abolished slavery. After the war, white southerners created legislation (known as Black Codes) to prevent freedmen from exercising their rights, prompting Congress to pass the Civil Rights Act in 1866, which guaranteed black citizenship.
2. Citizens of the United States and the State in which they reside are all persons born or naturalized in the United States and subject to its authority. No State shall make or execute any law that restricts the privileges or immunities of United States citizens; no State shall deprive any person of life, liberty, or property without due process of law; and no State shall refuse equal protection of the laws to any person within its jurisdiction.
3. The right to vote of United States citizens shall not be denied or abridged by the United States or any State on the basis of race, color, or past servitude.
4. They are generally known as the Civil War Amendments, and I believe they were designed to ensure equality for newly liberated slaves.
