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?
Sentence (from "Anastasia (1956 film)"): 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.
Relevant evidence: No
