The Liechtenstein dynasty, from which the principality takes its name, is the family which reigns by constitutional, hereditary right over the nation of Liechtenstein. Only dynastic members of the House of Liechtenstein are eligible to inherit the throne, and the dynasty's membership, rights and responsibilities are defined by a law of the family, which is enforced by the reigning Prince and may be altered by vote among the family's dynasts, but which may not be altered by the Government or Parliament of Liechtenstein.
