She died aged 78, seven months after her older sister, Xenia. At the end of her life and afterwards, Olga was widely labelled the last Grand Duchess of Imperial Russia. Olga was the youngest daughter of Emperor Alexander III and his consort, Empress Marie, formerly Princess Dagmar of Denmark. She was born in the purple (i.e., during her father's reign) on 13 June 1882 in the Peterhof Palace, west of central Saint Petersburg. Her birth was announced by a traditional 101-gun salute from the ramparts of the Peter and Paul Fortress, and similar salutes throughout the Russian Empire. Her mother, advised by her sister, Alexandra, Princess of Wales, placed Olga in the care of an English nanny, Elizabeth Franklin. The Russian imperial family was a frequent target for assassins, so for safety reasons the Grand Duchess was raised at the country palace of Gatchina, about 50 miles (80 km) west of Saint Petersburg. Although Olga and her siblings lived in a palace, conditions in the nursery were modest, even Spartan. They slept on hard camp beds, rose at dawn, washed in cold water, and ate a simple porridge for breakfast. Olga left Gatchina for the first time in 1888 when the imperial family visited the Caucasus. On 29 October, their return train approached the small town of Borki at speed. Olga's parents and their four older children were eating lunch in the dining-car when the train lurched violently and came off the rails. The carriage was torn open; the heavy iron roof caved in, and the wheels and floor of the car were sliced off. Survivors claimed the Tsar crawled out from beneath the crushed roof, and held it up with "a Herculean effort" so that the others could escape; a story subsequently considered unbelievable. There were 21 fatalities. Empress Marie helped tend the wounded, and made makeshift bandages from her own clothes. An official investigation found that the crash was an accident, but it was widely and falsely believed that two bombs had been planted on the line. The Grand Duchess and her siblings were taught at home by private tutors. Subjects included history, geography, Russian, English, and French, as well as drawing and dancing. Physical activities such as equestrianism were taught at an early age, and the children became expert riders. The family was deeply religious. While Christmas and Easter were times of celebration and extravagance, Lent was strictly observed—meat, dairy products and any form of entertainment were avoided.
