Problem: Question: What year did Alexander die? Passage:The Bagration family's genealogy traces back at least to the medieval era in its male line and hundreds of years further back as rulers in the female line. Leonida's grandfather, Prince Alexander Bagration of Mukhrani, was born in 1853 in Georgia's historical capital Tbilisi, then part of the Russian Empire, and was killed by Bolsheviks at Pyatigorsk in 1918 during the Russian revolution. Fearing for their lives, the family took refuge in Constantinople, then spent eight months in Germany before returning to Tbilisi, now capital of the Georgian Soviet Socialist Republic, to re-claim a portion of property which, as émigrés they risked losing to total confiscation. Although the family made repairs to their home and Leonida would recall her grandfather's insistence that they continue to dine formally on silver plate to retain their sense of propriety, they were eventually deprived of all but two rooms of their old palace and subjected to harassment. Thanks to the intervention of Maxim Gorky, who had enjoyed the patronage of the Bagrations, in 1931 they once again fled the Soviet Union, going into exile in Spain. The family moved to France, where Leonida's grandmother and relations had already settled.
