He had a very close relationship with the Tzar and Tzarina related to their only son, Alexei. Alexei was a hemophiliac (extremely dangerous at the time) and the Tzar and Tzarina believed in Raputin's ability to heal and keep safe their son. There are suggestions that the relationship to the Tzarina was sexual as well. We was a drunkard, a womanizer, and accused several times of rape if I recall correctly. He was despised by the Orthodox Church, many members of the nobility, and well...a lot of people.
He is an integral part of the story of the fall of Romanov dynasty as the royal family kept their son's illness a secret. So no one outside the family understood why they were associating with a peasant faith healer and a heretic if you listened to the church.
I honestly can't even start to explain all the intricacies of what was going on at the time. The whole story of the fall of the Romanovs is a sad but fascinating tale. Kind of the perfect storm of political issues, personalities, modernization, and the outbreak of the First World War. There are people who are far more well informed about this than me and likely have several corrections. If it interests you I'd suggest reading it or finding a good documentary.
Now for something related but very silly.
