Prince Felix Felixovich Yusupov, Count Sumarokov-Elston was a Russian aristocrat, Prince, and count from the Yusupov family. He is best known for participating in the assassination of Grigori Rasputin and marrying the niece of Czar Nicholas II.
The famous mystic's death was truly remarkable. According to Yusupov, he invited Rasputin to his home shortly after midnight and ushered him into the basement. Yusupov offered Rasputin tea and cakes which had been laced with cyanide. At first, Rasputin refused the cakes, but then began to eat them. To Yusupov's surprise, Rasputin did not appear to be affected by the poison.
Rasputin then asked for some Madeira wine (which had also been poisoned) and drank three glasses, but still showed no sign of distress. At around 2:30 am, Yusupov excused himself to go upstairs, where his fellow conspirators were waiting. Taking a revolver from Dmitry Pavlovich, Yusupov returned to the basement and, referring to a crucifix that was in the room, told Rasputin that he'd "better look at the crucifix and say a prayer", then shot him once in the chest. Believing him to be dead, they then drove to Rasputin's apartment, with Sukhotin wearing Rasputin's coat and hat, in an attempt to make it look as though Rasputin had returned home that night.
Upon returning to the Moika Palace, Yusupov went back to the basement to ensure that Rasputin was dead. Suddenly, Rasputin leaped up and attacked Yusupov, who, with some effort, freed himself and fled upstairs. Rasputin followed and made it into the palace's courtyard before being shot by Purishkevich and collapsing into a snowbank. The conspirators then wrapped Rasputin's body in cloth, drove it to the Petrovsky Bridge, and dropped it into the Malaya Nevka River.
In her 2017 book, Princess Olga Andreevna Romanoff wrote that Prince Felix was bi and that he and Grand Duke Dmitry Pavlovich were lovers. [1]
