The 14th Amendment, ratified in 1868, is significant because it explicitly granted citizenship to all persons born or naturalized in the United States, which included former slaves who had been freed following the Civil War. This amendment not only defined what it means to be a citizen but also aimed to protect the rights of citizens and ensure equal protection under the law.

The wording of the 14th Amendment was a direct response to the issues of citizenship and civil rights that arose from the end of slavery. It laid the groundwork for numerous landmark Supreme Court cases that further defined civil rights and liberties in the U.S. For instance, the equal protection clause has been central to many significant civil rights decisions.

The other amendments listed do not address citizenship for former slaves. The 12th Amendment deals with the election of the President and Vice President, the 16th Amendment concerns income tax, and the 18th Amendment enacted Prohibition of alcohol. None of these amendments pertain to citizenship rights or the status of former slaves in the United States.
