Please explain the incident of 'Bloody Sunday' during the Russian Revolution.
Some point to this event as changing the relationship between the Czar and his people, inevitably marking the end of any good will the latter held for the former. A group of protesters, consisting of men, women, and children, marched in St. Petersburg. Their primary motivation was to seek economic redress for their challenges. They were not seeking to instigate much of conflict, given the presence of women and children in the crowd. The crowd marched and encountered the armed forces of the Czar, and were met with fire from weapons. Many died in the process and as news spread around the nation that the Czar's army had mowed down unarmed men, women, and children, the perception was that the Czar held little in way of love for his people. The anti- establishment forces used Bloody Sunday as evidence that a change in government structure was needed and the Czar had to go.
This incident happened on January 22, 1905 in the city that was then called St. Petersburg (it was called Leningrad during Soviet times but is now back to its old name). The basic story is that a crowd of demonstrators was marching peacefully to give a petition to the Tsar. As it was trying to do this, the Imperial Guard opened fire on the marchers. The official death toll was 96 dead and 333 wounded, but that was a government figure and other people claim many more people died.
This was an important event because it made people lose their trust in the Tsar's government. They didn't have a lot of trust before, but after this, they pretty much lost what trust they had. Revolution followed soon after.
