A pretender is a claimant to an abolished throne or to a throne already occupied by somebody else. The English word pretend comes from the French word prétendre, meaning "to put forward, to profess or claim". The term pretender is also applied to those persons on whose behalf a claim to a throne is advanced, regardless of whether that person himself actually makes an active claim.Fact: date=August 2007 Significantly, the word pretender applies both to claimants with genuine rights to the throne (such as the various pretenders of the Wars of the Roses), and to those with fabricated claims (such as the pretender to Henry VII's throne Lambert Simnel). The papal equivalent of a pretender is an antipope.

Modern pretenders

The following list contains current pretenders. During the monarchical period of some countries listed here, there was no reigning house as it is known in the European sense – those are for example Tibet or the Central African Empire. These countries have a — in the column "House".

Germany

Some of the former German monarchies are not listed here because all eligible dynasts of the respective formerly reigning houses are extinct: The Grand Duchy of Mecklenburg-Schwerin in 2001, the duchy of Saxe-Altenburg in 1991 and the principalities of Schwarzburg-Rudolstadt and Schwarzburg-Sondershausen (since 1909 in personal union with Schwarzburg-Rudolstadt) in the male line in 1971. There may be potential claimants to the entirety of Schwarzburg, however.

Italy

Modena, Naples and Parma do not mean the Italian cities but the former states on the territory of present-day's Italy.

India

Satara, Surat, Alwar, Balasinor, Banganapalle, Baroda, Bhopal, Gwalior, Hyderabad, Idar, Indore, Jodhpur Kolhapur Mysore and Udaipur do not mean the Indian cities but the former states on the territory of present-day's India.

Pretenders in the Roman Empire

Ancient Rome knew many pretenders to the office of Roman Emperor, especially during the crisis of the Third Century.

These are customarily referred to as the Thirty Tyrants, which was an allusion to the Thirty Tyrants at Athens some five hundred years earlier; although the comparison is questionable, and the Romans were separate aspirants, not (as the Athenians were) a Committee of Public Safety. The Loeb translation of the appropriate chapter of the Augustan History therefore represents the Latin triginta tyranni by "Thirty Pretenders" to avoid this artificial and confusing parallel. Not all of them were afterwards considered pretenders; several were actually successful in becoming Emperor in at least in part of the Empire for a brief period.

The Byzantine Empire

Disputed successions to the Empire continued at Constantinople. Most seriously, after the fall of Constantinople to the Fourth Crusade in 1204, and its eventual recovery by Michael VIII Palaeologus, there came to be three Byzantine successor states, each of which claimed to be the Roman Empire, and several Latin claimants (including the Republic of Venice and the houses of Montferrat and Courtenay) to the Latin Empire the Crusaders had set up in its place. There were sometimes multiple claimants to some of the inheritances, as well.
