A constitutional prohibition barring the federal government and the states from granting hereditary ranks or aristocratic privileges to any person.
The legislature of New York enacts a statute naming Theresa Tucker Duchess of the Hudson Valley in recognition of her philanthropy. Theresa accepts the title and begins using it in official correspondence. A taxpayer sues, arguing the statute violates the federal Constitution. The court invalidates the statute because it confers a hereditary rank prohibited to the states.
Congressman Thomas Thompson receives an honorary knighthood from the United Kingdom without first obtaining congressional consent. He lists the title on his official congressional biography. A watchdog group files suit seeking to bar him from using the title in his federal capacity. The court orders him to renounce the title because the Constitution forbids federal officeholders from accepting foreign honors without approval.

A state enacts a law providing that the governorship passes automatically to the eldest child of the incumbent upon death. The designated heir claims the office after the governor dies. Opponents sue, asserting the statute creates a prohibited hereditary rank. The court invalidates the law because it grants an aristocratic succession privilege forbidden to states.
A federal agency regulation awards lifetime diplomatic immunity to the spouse and children of a favored official. The family members invoke the immunity during a criminal investigation. Prosecutors challenge the regulation as an unauthorized grant. The court strikes it down because it confers a hereditary-style legal privilege the Constitution withholds from the United States.
The state legislature adopts a resolution declaring a prominent donor and all descendants 'Peers of the Realm' with priority seating at all official state events. The donor and heirs begin asserting the priority. A citizen suit challenges the resolution. The court voids it because the grant establishes an aristocratic distinction prohibited to the states.
The clause bars the United States and the states from creating hereditary ranks or aristocratic privileges that confer formal legal status on a person or family line. It prevents the establishment of an official class system based on birth or grant of title. Economic or policy preferences that do not create hereditary legal rank fall outside its scope.

The prohibition targets grants that create formal hereditary rank or special legal status. Purely honorary or ceremonial designations without legal effect do not trigger the clause. The constitutional concern centers on the creation of an aristocratic class rather than on symbolic recognition alone.

A state cannot evade the prohibition by labeling a hereditary privilege with a different name. Courts examine the substance of the grant to determine whether it confers a hereditary legal advantage. Substance controls over form when the effect is to establish an aristocratic distinction.
