 It was originally established by the Soviet Union as a military honour during World War II, more precisely by Decree of the Presidium of the Supreme Soviet of the USSR of July 7, 1942.
 Its statute was amended by Decree of the Presidium of the Supreme Soviet of the USSR of February 26, 1947.
 It bears a similar name to the Imperial Order of St. Alexander Nevsky which had been established by Empress Catherine I of Russia in 1725, and continued to be bestowed by the heads of the House of Romanov after the 1917 Russian Revolution.
 The Order of Alexander Nevsky was reinstated by the Soviet Union, minus the words "Imperial" and "Saint", for award to officers of the army for personal courage and resolute leadership.
