The term 'Symbol of Sovereignty' is often used to refer to four objects: a CROWN, an ORB, a SCEPTER, and a THRONE. A CROWN is a headpiece worn by a monarch as a symbol of their power and authority. An ORB is a spherical object that is often held in the hand of a monarch as a symbol of their power. A SCEPTER is a staff or rod that is held in the hand of a monarch as a symbol of their power. Finally, a THRONE is a chair or seat that is used by a monarch as a symbol of their power and authority. All four of these symbols are used to represent the sovereignty of a monarch.
