The term "Fourteenth" typically refers to the ordinal number that comes after the thirteenth and before the fifteenth. It is often used to describe the position of an item in a sequence, such as the fourteenth day of the month or the fourteenth chapter of a book. In the context of U.S. history, the Fourteenth Amendment to the Constitution was ratified in 1868. This amendment addresses citizenship rights and equal protection under the law, significantly impacting civil rights in the United States. It was a crucial part of the Reconstruction Era, aimed at ensuring that former slaves received equal treatment.
