2. The decease of a royal or princely person; hence, also, the death of any illustrious person.

   Note: The demise of the crown is a transfer of the crown, royal authority, or kingdom, to a successor. Thus, when Edward IV. was driven from his throne for a few months by the house of Lancaster, this temporary transfer of his dignity was called a demise. Thus the natural death of a king or queen came to be denominated a demise, as by that event the crown is transferred to a successor.
   --Blackstone.

   Demise and redemise, a conveyance where there are mutual leases made from one to another of the same land, or something out of it.

   Syn: Death; decease; departure. See Death.
