In 1920 a woman in Berlin, Germany, attempted to kill herself by jumping off a bridge. She carried no identification and refused to tell her rescuers her name. She stayed silent for years – and then, when she finally did speak, said she was Grand Duchess Anastasia, the only surviving member of the Russian royal family.
Two years earlier on July 17, 1918, the deposed Russian czar Nicholas II, his family, and four attendants had been killed by a firing squad. The bodies were buried quickly and, almost immediately, rumors circulated that one or more of the five Romanov children had survived. Anastasia, the youngest of the czar's daughters, was most often named as the one who could have gotten away.
