What amendment says all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are U.S. citizens?

In plain English

The 14th Amendment says all persons born or naturalized in the United States, and subject to its jurisdiction, are U.S. citizens. It was added in 1868, after the Civil War. It made citizens of the people freed from slavery. It matters to you too — naturalized citizens are full citizens. That amendment is the 14th Amendment.
