Grand Duchess Olga Nikolaevna of Russia in the context of "Carol II of Romania"

Nicholas II (Nikolai Alexandrovich Romanov; 18 May [O.S. 6 May] 1868 – 17 July 1918) was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland from 1 November 1894 until his abdication in 1917. His reign of over 22 years marked the final chapter of the Romanov dynasty, which had ruled Russia for more than three centuries. Nicholas married Alix of Hesse (later Alexandra Feodorovna), and they had five children: four daughters, Olga, Tatiana, Maria, and Anastasia, and a son, Alexei, the Tsesarevich.

Born in Tsarskoye Selo, Nicholas was the eldest son of Emperor Alexander III and Empress Maria Feodorovna. He was educated privately and trained for military service, but was widely considered ill-prepared for the demands of ruling a vast empire. As a constitutional monarch, he resisted political reform and retained autocratic control, despite the establishment of the Duma. His reign saw significant industrial growth and diplomatic engagement, including the Hague Conventions and the Anglo-Russian Convention of 1907, but was also marked by domestic unrest, military defeats, and widespread criticism.

Grand Duchess Tatiana Nikolaevna of Russia (Russian: Татьяна Николаевна Романова, romanized: Tatyana Nikolaevna Romanova;10 June [O.S. 29 May] 1897 – 17 July 1918) was the second daughter of Tsar Nicholas II, the last monarch of Russia, and of Tsarina Alexandra. She was born at Peterhof Palace, near Saint Petersburg.

Tatiana was the younger sister of Grand Duchess Olga and the elder sister of Grand Duchess Maria, Grand Duchess Anastasia, and Tsarevich Alexei. She was considered to be the most beautiful of all her sisters and the most aristocratic in appearance. She was known amongst her siblings as "the governess" for her domineering but also maternal ways. Tatiana was the closest of all the children to her mother (Tsarina Alexandra), often spending many hours reading to her. During World War I, she chaired many charitable committees and (along with her older sister, Grand Duchess Olga) trained to become a nurse. She tended to wounded soldiers on the grounds of Tsarskoye Selo from 1914 to 1917. Her time as a nurse came to an end with her family's arrest in 1917 after the first Russian Revolution.

Grand Duchess Anastasia Nikolaevna of Russia (Russian: Анастасия Николаевна Романова, romanized: Anastasiya Nikolaevna Romanova; 18 June [O.S. 5 June] 1901 – 17 July 1918) was the youngest daughter of Tsar Nicholas II, the last sovereign of Imperial Russia, and his wife, Tsarina Alexandra Feodorovna.

Anastasia was the younger sister of Grand Duchesses Olga, Tatiana, and Maria (commonly known together as the OTMA sisters) and was the elder sister of Alexei Nikolaevich, Tsarevich of Russia. She was murdered with her family by a group of Bolsheviks in Yekaterinburg on 17 July 1918.

The abdicated Russian Imperial Romanov family (Tsar Nicholas II of Russia, his wife Alexandra Feodorovna, and their five children: Olga, Tatiana, Maria, Anastasia, and Alexei) were shot and stabbed to death by Bolshevik revolutionaries under Yakov Yurovsky on the orders of the Ural Regional Soviet in Yekaterinburg on the night of 16–17 July 1918. Also killed that night were members of the imperial entourage who had accompanied them: court physician Eugene Botkin; lady-in-waiting Anna Demidova; footman Alexei Trupp; and head cook Ivan Kharitonov. The bodies were taken to the Koptyaki forest, where they were stripped, mutilated with grenades and acid to prevent identification, and buried.

Following the February Revolution in 1917, the Romanovs and their servants had been imprisoned in the Alexander Palace before being moved to Tobolsk, Siberia, in the aftermath of the October Revolution. They were next moved to a house in Yekaterinburg, near the Ural Mountains, before their execution in July 1918. The Bolsheviks initially announced only Nicholas's death. For the next eight years, the Soviet leadership maintained a systematic web of disinformation regarding his family, making claims ranging from murder by left-wing revolutionaries in September 1919, to outright denial of their deaths in April 1922.
