 A miniature picture in the "Chronica Aulae Regiae" written in the great abbey outside Prague depicts his mother Elizabeth, a queen of Bohemia, wearing an open crown, while his two wives, who had imperial titles, have closed ones.During the machinations that surrounded the introduction of the imperial crown under Henry VIII (see the section below Legal usage), the closed crown, became associated as a symbolic representation of the English Crown as an imperial crown, and has remained so until this day.The Silk Imperial Crown of Russia was used as an official coronation gift of the Russian Empire for the coronation of Nicholas II, the last Emperor of the Romanov line.
