She was assassinated along with the rest of her family in the Ipatiev House in Ekaterinburg on July 17, 1918. Although rumors of her survival had persisted for several decades, DNA testing in 1994 on the bodies executed in Ekaterinburg have established that they were indeed the Romanovs, although two bodies - those of Alexei and one of the daughters (variously said to be Anastasia, Tatiana or Maria) - were missing, likely because they had been cremated.
She has been impersonated on several occasions. The two most famous instances were an American woman named Eugenia Smith and a woman calling herself "Anna Anderson."
The possible survival of Anastasia has also been the subject of several films. Although the earliest such film was made in 1928 and the most recent a historically inaccurate 1997 musical animated film Anastasia, the most famous is probably the 1956 Anastasia starring Ingrid Bergman, Yul Brynner, and Helen Hayes.
Another Grand Duchess Anastasia of Russia (Anastasia Mikhailovna Romanova) (July 28, 1860 - March 11, 1922) was the daughter of Grand Duke Mikhail of Russia. She was married to Grand Duke Friedrich of Mecklenburg-Schwerin.
