Tatiana was killed by Bolsheviks on July 17, 1918 with the rest of her family and some of their servants, during the Russian Revolution. Their mass grave was found later in Siberia after some speculation that one of her sisters, mainly presumed to be Anastasia, had escaped. Tatiana and her family were then buried in St. Petersburg, Russia on July 17, 1998. They were made saints by the Russian Orthodox Church in 2000.
