What title was held by Nicholas II whose eldest daughter was called Grand Duchess of Russia and whose reign saw the fall of the Russian Empire?
Tsar of the Russian Empire
Nicholas II of Russia
Nicholas II or Nikolai II (Russian: Николай II Алекса́ндрович , "Nikolay II Aleksandrovich" ; 18 May [O.S. 6 May] 1868 – 17 July 1918) was the last Emperor of Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917.
 His reign saw the fall of the Russian Empire from being one of the foremost great powers of the world to economic and military collapse.
 Due to the Khodynka Tragedy, anti-Semitic pogroms, Bloody Sunday, the violent suppression of the 1905 Revolution, the execution of political opponents and his perceived responsibility for the Russo-Japanese War, he was given the nickname Nicholas the Bloody by his political adversaries.
 Soviet historiography portrayed Nicholas as a weak and incompetent leader, whose decisions led to military defeats and the deaths of millions of his subjects.
Grand Duchess Olga Nikolaevna of Russia
Grand Duchess Olga Nikolaevna of Russia (Olga Nikolaevna Romanova) (Russian: Великая Княжна Ольга Николаевна ; ] (Velikaya Knyazhna Ol'ga Nikolaevna); November 15 [O.S. November 3] 1895 – July 17, 1918) was the eldest daughter of the last Tsar of the Russian Empire, Emperor Nicholas II, and of Empress Alexandra of Russia.
Nicholas I of Russia
Nicholas I (Russian: Николай I Павлович , "Nikolay I Pavlovich" ; 6 July [O.S. 25 June] 1796 – 2 March [O.S. 18 February] 1855 ) was the Emperor of Russia from 1825 until 1855.
 He was also the King of Poland and Grand Duke of Finland.
 He is best known as a political conservative whose reign was marked by geographical expansion, repression of dissent, economic stagnation, poor administrative policies, a corrupt bureaucracy, and frequent wars that culminated in Russia's defeat in the Crimean War of 1853–56.
 His biographer Nicholas V. Riasanovsky says that Nicholas displayed determination, singleness of purpose, and an iron will, along with a powerful sense of duty and a dedication to very hard work.
 He saw himself as a soldier—a junior officer totally consumed by spit and polish.
 A handsome man, he was highly nervous and aggressive.
 Trained as an engineer, he was a stickler for minute detail.
 In his public persona, says Riasanovsky, "Nicholas I came to represent autocracy personified: infinitely majestic, determined and powerful, hard as stone, and relentless as fate."
 His reign had an ideology called "Official Nationality" that was proclaimed officially in 1833.
 It was a reactionary policy based on orthodoxy in religion, autocracy in government, and Russian nationalism.
 He was the younger brother of his predecessor, Alexander I.
 Nicholas inherited his brother's throne despite the failed Decembrist revolt against him and went on to become the most reactionary of all Russian leaders.
 His aggressive foreign policy involved many expensive wars, having a disastrous effect on the empire's finances. Grand Duchess Maria Kirillovna of Russia
Grand Duchess Maria Kirillovna of Russia, (2 February 1907 – 25 October 1951) was the eldest daughter of Grand Duke Kirill Vladimirovich of Russia and Grand Duchess Victoria Feodorovna.
 She was born in Coburg when her parents were in exile because their marriage had not been approved by Tsar Nicholas II.
 She was generally called "Marie," the French version of her name, or by the Russian nickname "Masha."
 The family returned to Russia prior to World War I, but was forced to flee following the Russian Revolution of 1917. Grand Duchess Maria Alexandrovna of Russia
Grand Duchess Maria Alexandrovna of Russia (later Duchess of Edinburgh and Duchess of Saxe-Coburg and Gotha; Russian: Мария Александровна ; 17 October [O.S. 5 October] 1853 – 24 October 1920) was the fifth child and only surviving daughter of Emperor Alexander II of Russia and his first wife Princess Marie of Hesse and by Rhine.
 She was the younger sister of Emperor Alexander III of Russia and the paternal aunt of Russia's last Emperor, Nicholas II. Princess Vera Constantinovna of Russia
Princess Vera Constantinovna of Russia, also Vera Konstantinovna (Russian: Вера Константиновна Романова ; 24 April 1906 – 11 January 2001), was the youngest child of Grand Duke Konstantine Konstantinovich of Russia and his wife, Grand Duchess Elizabeth Mavrikievna.
 A great-granddaughter of Tsar Nicholas I of Russia, she was born in the Russian Empire and was a childhood playmate of the younger children of Emperor Nicholas II of Russia.
 She lost much of her family during World War I and the Russian Revolution.
 At age twelve, she escaped revolutionary Russia, fleeing with her mother and brother George to Sweden.
 She spent the rest of her long life in exile, first in Western Europe and from the 1950s in the United States. Princess Irina Alexandrovna of Russia
Princess Irina Alexandrovna of Russia (Russian: Княжна Ирина Александровна Романова ; 15 July (OS: 3 July), 1895, Peterhof, Saint Petersburg, Russia – 26 February 1970, Paris, France) was the only daughter and eldest child of Grand Duke Alexander Mikhailovich of Russia and Grand Duchess Xenia Alexandrovna of Russia.
 She was also the only niece of Tsar Nicholas II of Russia, and the wife of the wealthiest man in Imperial Russia, Prince Felix Felixovich Yusupov, one of the men who murdered Grigori Rasputin, "holy healer" to her cousin, the hemophiliac Tsarevich Alexei Nikolaevich of Russia, in 1916. Grand Duchess Elena Vladimirovna of Russia
Grand Duchess Elena Vladimirovna of Russia (17 January 1882 – 13 March 1957), sometimes known as Helen, Helena, Helene, Ellen, Yelena, Hélène, or Eleni, was a Russian grand duchess as the only daughter and youngest child of Grand Duke Vladimir Alexandrovich of Russia and Duchess Marie of Mecklenburg-Schwerin.
 Her husband was Prince Nicholas of Greece and Denmark and they were both first cousins of Tsar Nicholas II of Russia. Anastasia (1956 film)
Anastasia is a 1956 American historical drama film directed by Anatole Litvak.
 Set in interwar France, the film follows the story of a suicidal amnesiac (Ingrid Bergman), whose remarkable resemblance to the Grand Duchess Anastasia Nikolaevna of Russia — the youngest daughter of the late Tsar Nicholas II and Empress Alexandra Feodorovna, who is rumored to have survived the execution of her family — draws her into a plot devised by the former Russian White General Bounine (Yul Brynner) and his associates to swindle from the Grand Duchess an inheritance of £10 million.
 However, the ultimate hurdle to their plan is the exiled Russian aristocracy — in particular the Dowager Empress Marie Feodorovna (Helen Hayes) — whom their handpicked claimant must convince of her legitimacy if they wish for their scheme to succeed. Grand Duchess Xenia Alexandrovna of Russia
Grand Duchess Xenia Alexandrovna of Russia (Russian: Ксения Александровна Романова ; 6 April [O.S. 25 March] 1875 – 20 April 1960) was the elder daughter and fourth child of Emperor Alexander III of Russia and Empress Maria Feodorovna of Russia (née Princess Dagmar of Denmark) and the sister of Emperor Nicholas II.
 She married a cousin, Grand Duke Alexander Mikhailovich of Russia, with whom she had seven children.
 She was the mother-in-law of Felix Yusupov and a cousin of Grand Duke Dmitri Pavlovich of Russia who, together, killed Grigori Rasputin, holy healer to her nephew, the haemophiliac Tsarevich Alexei Nikolaevich of Russia.
 During her brother's reign she recorded in her diary and letters increasing concern about his rule.
 After the fall of the monarchy in February 1917 she fled Russia, eventually settling in the United Kingdom.
