An official head-dress worn by a king or queen. The modern crown originated with the diadem, an embroidered fillet worn by Eastern rulers, for which a golden band was later substituted. A laurel crown was granted by the Greeks to a victor in the games, and by the Romans to a triumphant general. Crowns came into use among the Byzantine emperors and the European kings after the fall of the Western Empire. Perhaps the oldest in Europe is the Iron Crown of Lombardy, made in 591. The crown of Charlemagne, preserved in Vienna, consists of eight gold plates. Before the Norman Conquest, kings of England certainly wore crowns, and from the Conquest to the Commonwealth, each king had two crowns. The old regalia was broken up under the Commonwealth, and a new set was made after the Restoration.
