The Fourteenth Amendment to the U.S. Constitution, a cornerstone of civil rights, is ratified. It was passed by Congress two years earlier on June 13, 1866. South Carolina became the 28th State to ratify it on July 9, 1868 at which time the constitutionally necessary approval by three-quarters of the states (28 of 37) was reached. Secretary of State William Henry Seward certified on July 28 that the 14th Amendment had become part of the U.S. Constitution.
The Fourteen Amendment defines citizenship and guaranteeing due process and equal protection under the law. It granted citizenship to all persons born or naturalized in the United States, including formerly enslaved people. Kentucky, Delaware, and Maryland rejected the proposed amendment outright, and California did so later. Ohio, New Jersey, and Oregon rescinded their ratifications. If the rescissions were allowed, only nineteen states, not the requisite twenty, would have ratified. More
