Grigori Rasputin was a Russian mystic and healer who became famous in the early 20th century. Born in 1869, he gained influence in the royal court of Tsar Nicholas II and his wife, Alexandra, due to his alleged ability to heal their son, Alexei, who suffered from hemophilia. Rasputin's presence in the palace stirred controversy and suspicion among the nobility and the public. Despite his controversial reputation, Rasputin was seen by some as a spiritual guide. His influence over the royal family contributed to the growing discontent that led to the Russian Revolution in 1917. Ultimately, he was assassinated by a group of nobles who feared his power and the impact he had on the monarchy.
