Grigori Rasputin was a purported mystic that became an adviser to Tsar Nicholas II of Russia in the early twentieth century. He was first invited to the court when the Tsar's wife, Tsaritsa Alexandra became desperate to find an effective medical treatment for her son, Tsarevich Alexei, who suffered from hemophilia. Rasputin's treatments of the boy, however effective they may actually have been, allowed him to earn the trust of Alexei's parents, Alexandra in particular. As a result, he became a close confidante of the monarchy.
Despite his influence, Rasputin was not popular among Russian nobility and was accused of actions ranging from raping a nun to the decline of Russia's economy. He was eventually subjected to a series of assassination attempts, of which his survival has become legend. After recovering from a stab wound to his gut delivered by a former prostitute, a group of nobles tricked him into a visit with the purpose of killing him. They served him cake laced with lethal doses of poison, but when that failed to have any effect, one of the conspirators, Prince Felix Yusupov, shot him in the back. However, as the conspirators prepared to leave, Yusupov realized that he forgot his coat. When he returned to retrieve it, Rasputin leaped up from the floor and attacked him.
Rasputin was again shot, but when this still failed to kill him, the conspirators beat him, bound him in a carpet and threw him into the Neva River. Despite his injuries, evidence suggests that Rasputin managed to free himself from his bonds before finally drowning.
As a legendary, controversial figure of Russian politics, Rasputin has appeared in numerous media over the years, often with some form of fantastic slant that emphasizes his background as a supposed mystic and his apparent difficulty to murder.
