Which day is the lowest point in Russian history, and the point were Russians lose their faith in the Czar? * September Revolt
Boston Tea Party
February Massacre
Bloody Sunday

the answer is A the September Revolt however here is another reason why they really lost faith. A so called healer named Rasputin was influencing the Tzar and the nobles as well as the people weren't very happy about that. the reason why the Tzar listened to  Rasputin was because  Rasputin said he could heal the Tsar's son from a disease.

Explanation:

the pogroms became known as kristallnacht, the "night of shattered glass," for the shattered glass from the store windows that littered the streets. the morning after the pogroms 30,000 german jewish men were arrested for the "crime" of being jewish and sent to concentration camps, where hundreds of them perished.
