Russian regalia used prior to the Great Imperial Crown. The crown is styled after the Monomakh Cap, and was made for Tsar Michael Fyodorovich by Kremlin masters in 1627. The orb and sceptre are of Western-European origin[citation needed] and may have been given to Tsar Boris Godunov in 1604.
The Imperial crown of Russia, also known as the Great Imperial Crown of Russian Empire, was used for the coronation of the monarchs of Russia from 1762 until the Russian monarchy's abolition in 1917.
