tsarina Alexandra's most trusted advisor was?

Nicholas II was not her advisor, he was her husband and her Tsar. So that rules him out..

Saint Michael was not an advisor, he was her God. So that rles him out..

Alexander Popov (I'm not sure this is Protopopov) was an advisor but not as trusted as..

Rasputin, who she relied on bove all other advisors and allowed him to make governmental decisions appoint and hire ministers during her regency.

So my answer is Rasputin.

Tsarina Alexandra

A; Rasputin/ She didn't trust any advisers and did not listen to any family members. Because her son's life was in Rasputin's hands.

Rasputin!

A: Rasputin.

Rasputin domnated the Queen because he had the demonic ability to bring relief to her son who had a mental illness, and often experienced periods of pain or distress that rasputin could soothe.

She used to be the spouse of the Tsar and now not the inheritor to the throne so Nicholas held all energy proper up untill he left to take over individual command of the Russian entrance in WW1 he then left his spouse the Tsarina to manipulate in his stead nevertheless she used to be nto above all well at governing and used to be unpopular seeing that she used to be German- Russias enemy.

Ra Ra Rasputin dear girl!

Apparently he was Russia's greatest love machine.

Rasputin but only she trusted him.

Test? are you asking us to help you cheat on your test?

Cause, you know, that's kinda common knowledge, and if you are doing homework, it would be ten times faster to just do it yourself.
