Grand Duchess Maria Nikolaevna of Russia was the third daughter of Tsar Nicholas II of Russia and Tsarina Alexandra Feodorovna. Her murder following the Russian Revolution of 1917 resulted in her canonization as a passion bearer by the Russian Orthodox Church.

Alexandra Feodorovna, Princess Alix of Hesse and by Rhine at birth, was the last Empress of Russia as the consort of Emperor Nicholas II from their marriage on 26 November [O.S. 14 November] 1894 until his forced abdication on 15 March [O.S. 2 March] 1917. A favourite granddaughter of Queen Victoria of the United Kingdom, she was, like her grandmother, one of the most famous royal carriers of haemophilia and bore a haemophiliac heir, Alexei Nikolaevich, Tsarevich of Russia. Her reputation for encouraging her husband's resistance to the surrender of autocratic authority and her known faith in the Russian mystic Grigori Rasputin severely damaged her popularity and that of the Romanov monarchy in its final years. She and her immediate family were all murdered while in Bolshevik captivity in 1918, during the Russian Revolution. In 2000, the Russian Orthodox Church canonized her as Saint Alexandra the Passion Bearer.
