Grigori Rasputin, Russian mystic and spiritual advisor to the Romanovs and a highly influential figure in the court of Tsar Nicholas II.

Reportedly, Rasputin’s first assassination attempt occurred in 1914, when the prostitute Khioniya Guseva stabbed him in the gut with a dagger in what was thought to be a mortal wound. Eyewitnesses claim that as Rasputin’s entrails fell from his stomach Guseva shouted, “I’ve killed the antichrist.” Though Rasputin survived the attack, his demeanor changed permanently.

In 1916, the country’s distaste for Rasputin hit an all-time high, and a group of conspirators including Grand Duke Dmitri Pavlovich and Prince Felix Yusupov set out to kill him. Using Yusupov’s wife to lure Rasputin to their home, the conspirators fed Rasputin wine and cakes laced with cyanide. Though it was reportedly enough poison to kill five men, Rasputin was unaffected.

Unperturbed, the conspirators continued their attack by beating him repeatedly, then shooting him in the back and causing him to fall to the floor. Yet Rasputin, much like antibiotic-resistant pathogen, still wasn’t dead. According to some, Rasputin jumped up violently, only to be shot several more times. The men then wrapped the body in a sheet or carpet and tossed him into the Neva River.

Rasputin’s body was pulled from the water three days later. Though autopsy reports differ, most attest that he was still alive when thrown into the water and that from the positioning of his body, he had tried to break free before either drowning or dying from hypothermia. The exact cause of death has been debated for decades.
