The 400th anniversary of the Romanov dynasty is marked on the 6th of March. Michael Romanov, whose grandfather, Nikita, wa a central adviser to Ivan the Terrible, was unanimously elected Tsar of Russia by a national assembly on 21 February 1613. Since that time, Romanov family, as the second and last Russian imperial dynasty, ruled the country right until 1917. The February Revolution resulted in abdication of Nicholas II in favor of his brother Grand Duke Michael Alexandrovich. The latter declined to accept the crown, terminating the Romanov dynasty's rule over Russia.
