Approved by Congress in 1810 as a proposed 13th Amendment, the Titles of Nobility Amendment was designed to strip U.S. citizenship from any citizen who accepted an aristocratic title from a foreign country. Ratified by tweleve states (the last in 1812) the amendment is still pending but would require ratification by an additional twenty-six states. It was erroneously included as the 13th Amendment in some early-nineteenth-century publications of the Constitution despite never having been ratified. “Thirteenthers” is a term sometimes used to refer to people who believe it was in fact ratified, or those who support its ratification now.
