A constitutional prohibition barring the United States and the states from granting hereditary ranks or formal titles that confer aristocratic status. The clause prevents creation of an official class distinguished by inherited privilege and bars federal officeholders from accepting foreign titles without congressional consent.
The legislature of a coastal state passes a statute bestowing the hereditary title of Viscount on a prominent shipping family in recognition of generations of service. Nathan Nguyen, a descendant, seeks to register the title with state agencies for use in official documents. The state attorney general blocks the registration because the enactment directly contravenes the federal prohibition on state grants of nobility.
A sitting cabinet secretary receives an honorary dukedom from a European monarch for diplomatic efforts. Nina Nielsen, the secretary's chief of staff, advises that acceptance requires prior congressional approval under the constitutional bar. Without that consent the title cannot be used in any official capacity or retained while the secretary remains in federal service.

A federal public-works statute reserves a percentage of contracts for businesses owned by members of designated racial groups. Naomi Norton, an unsuccessful bidder, argues the program functions as a hereditary privilege akin to nobility. The reviewing court rejects the claim because the classification rests on race rather than inherited rank and therefore falls outside the titles-of-nobility prohibition.
Coal companies hold deeds that waive surface-owner liability for subsidence damage. After a state statute voids those waivers to protect structures, Noah Nakamura, a surface owner, sues to enforce the new protections. The companies contend the statute creates a privileged class of surface owners equivalent to nobility. The court dismisses the argument as unrelated to hereditary titles.
Mining firms purchase support estates to extract coal without liability for surface damage. A state subsidence law restricts that extraction to protect public resources. Nicole Navarro, representing the firms, asserts the law effectively grants a new form of hereditary privilege to surface owners. The court holds that the regulation addresses land-use policy and does not implicate the constitutional ban on titles of nobility.
The clause forbids legislative grants that confer formal hereditary rank or status such as duke or earl. It prevents the creation of an aristocratic class and bars federal officeholders from accepting foreign titles without congressional consent. Economic preferences or regulatory classifications do not trigger the prohibition.

No. The clause targets only grants of hereditary rank or aristocratic status. A law that increases penalties for trafficking in counterfeit luxury goods or that reserves contracts for certain businesses does not create a formal title and therefore falls outside the prohibition.

No. Article I Section 10 flatly prohibits states from granting any title of nobility. Congressional consent is required only for certain other state actions listed in the same section, not for titles of nobility.
