The first article of the Edict of Moulins (1566) declared that the royal domain (defined in the second article as all the land controlled by the crown for more than ten years) could not be alienated, except in two cases: by interlocking, in the case of financial emergency, with a perpetual option to repurchase the land; and to form an appanage, which must return to the crown in its original state on the extinction of the male line. The (incumbent) therefore could not separate himself from his appanage in any way.
