Photographs have long been used to capture memories, historical events, landscapes, and more. However, and quite sadly, they also sometimes capture tragedies, horror stories, and dark moments in human history.

These pictures don't look too out of the ordinary, but don't let that fool you. There is some disturbing stuff going on behind the scenes.

The original photo (top left) was taken at the Fifteenth Leningrad Regional Party Conference in 1924 or 1925. It shows Nikolai Antipov (left), Joseph Stalin, Sergei Kirov (right), and Nikolai Shvernik (far right). Antiopov, who rose to become Deputy Chairman of the Council of People’s Commissars, was the first to fall out of Stalin’s favor. Shvernik vanished next. Readers can see he was airbrushed out of the photo, but Shvernik was lucky. He is the only person in the original photo to survive Stalin, whose enemies often had a penchant for dying unexpectedly.
