Grigori Yefimovich Rasputin (Russian: Григорий Ефимович Распутин [ɡrʲɪˈɡorʲɪj jɪˈfʲiməvʲɪtɕ rɐˈsputʲɪn]) (22 January [O.S. 10 January] 1869 – 29 December [O.S. 16 December] 1916) was a Russian mystic who is perceived as having influenced the latter days of the Russian Emperor Nicholas II, his wife Alexandra, and their only son Alexei. Rasputin had often been called the "Mad Monk", while others considered him a "strannik" (or religious pilgrim) and even a starets (ста́рец, "elder", a title usually reserved for monk-confessors), believing him to be a psychic and faith healer.
It has been argued that Rasputin helped to discredit the tsarist government, leading to the fall of the Romanov dynasty, in 1917. Contemporary opinions saw Rasputin variously as a saintly mystic, visionary, healer and prophet or, on the contrary, as a debauched religious charlatan. There has been much uncertainty over Rasputin's life and influence as accounts of his life have often been based on dubious memoirs, hearsay and legend.
