Rasputin was the advisor of whom?

Rasputin's role in history can be defined in many ways- "shaman", "madman", "Mad Monk", or even "doctor". Recall that Tsar Nicholas the II's son had hemophilia. Fearing that they would not have a Romanov heir, the Tsar & the Tsarina were immediately drawn to Rasputin. He supposedly had healing techniques that "cured" Tsarevich Alexei. Because of his successes, the Tsarina placed a lot of trust in him. In turn, Rasputin would come to advise not only Alexei and the Tsarina, but also Tsar Nicholas the II in political affairs.
