In English history the system of appanages never played any great part, and the term is now properly applied only to the appanages of the crown: the duchy of Cornwall, assigned to the king's eldest son at birth, or on his father's accession to the crown, and the duchy of Lancaster.
Lands and lordships thus bestowed constituted the appanages, which interfered so greatly with the formation of ancient France.
The Constituent Assembly, by the law dated the 22nd of November 1790, decided that in future there should be no appanages in real estate, and that younger sons of monarchs, married and over twenty-five years of age, should be provided for by yearly grants (rentes apanageres) from the public funds.
The laws of the 13th of August and the 21st of December 1790 revoked all the existing appanages, except those of the Luxembourg Palace and the Palais Royal.
Napoleon, by the senatus-consulte of the 30th of January 1810, resolved to create appanages for the emperor's princely descendants, such appanages to consist for the most part of lands on French soil.
