In this photo taken in July 4, 1917, provided by Karl Bulla Historical Foundation, Russian troops fire on demonstrators with machine guns, on the corner of Nevsky Prospect and Sadovaya Street, in St.Petersburg, Russia. The 1917 Bolshevik Revolution was long before the digital revolution allowed anyone to instantly document events. But the clumsy cameras of the time still caught some images that capture the period's drama. (Karl Bulla, Karl Bulla Historical Foundation via AP)
