Question: 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?

<P0-S0> 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. <P0-S1>  She was born in Coburg when her parents were in exile because their marriage had not been approved by Tsar Nicholas II. <P0-S2>  She was generally called "Marie," the French version of her name, or by the Russian nickname "Masha." <P0-S3>  The family returned to Russia prior to World War I, but was forced to flee following the Russian Revolution of 1917. <SEP> <P1-S0> 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. <SEP> <P2-S0> 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. <P2-S1>  He was also the King of Poland and Grand Duke of Finland. <P2-S2>  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. <P2-S3>  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. <P2-S4>  He saw himself as a soldier—a junior officer totally consumed by spit and polish. <P2-S5>  A handsome man, he was highly nervous and aggressive. <P2-S6>  Trained as an engineer, he was a stickler for minute detail. <P2-S7>  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." <P2-S8>  His reign had an ideology called "Official Nationality" that was proclaimed officially in 1833. <P2-S9>  It was a reactionary policy based on orthodoxy in religion, autocracy in government, and Russian nationalism. <P2-S10>  He was the younger brother of his predecessor, Alexander I. <P2-S11>  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. <P2-S12>  His aggressive foreign policy involved many expensive wars, having a disastrous effect on the empire's finances. <SEP> <P3-S0> 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. <P3-S1>  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. <P3-S2>  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. <P3-S3>  Soviet historiography portrayed Nicholas as a weak and incompetent leader, whose decisions led to military defeats and the deaths of millions of his subjects.
