Tsarevna Maria Feodorovna, née Princess Dagmar of Denmark, was married to Tsar Alexander III in 1866, and she became tsaritsa of Russia in 1881.

Provenance: The Danish doctor Carl Immanuel Krebs (1889–1971), who was a Danish Red Cross delegate in Russia during World War I, the revolution in 1917 and the subsequent civil war. Thence by descents until today. In the beginning of 1918, the Danish diplomate representative in St. Petersburg, Harald Scavenius, sent the Danish government as well as King Christian X and Queen Alexandrine of Denmark a report on the health status of the Russian Imperial family. Tsaritsa Maria Feodorovna was the King's aunt, while the Queen had uncles and cousins in Russia. When they read the report and knew of their relatives in captivity, they were of course worried and asked Harald Scavenius if he could help. The Danish diplomate representative knew the brave and energetic Carl Krebs and asked him to help Tsaritsa Maria Feodorovna, who was at this time in Soviet captivity at the Crimea. Carl Krebs subsequently left for Southern Russia in the beginning of 1918 with food and 50,000 rubles to the Tsaritsa. His journey was dangerous but he did not only succeed in this trip - he also got the opportunity to meet the Tsaritsa personally. At the meeting, the Soviet commissioner made the condition that Carl Krebs and the Tsaritsa were not allowed to speak Danish. But when Carl Krebs and the Tsaritsa were talking she changed to Danish and said very popularly “I do not give a damn!” Of course Tsaritsa Maria Feodorovna had no kind feelings for the Soviet. Carl Krebs subsequently wrote a report about the visit, which was handed to King Christian X and Queen Alexandrine of Denmark. Tsaritsa Maria Feodorovna was liberated in 1919, when she was sailed to England and shortly after to Denmark.
