It's quite sad to think of all the events and occurrences that have happened throughout history that were never able to be documented through photos or videos. We can read about many things, and use our imaginations, but the effect isn't quite the same as having visuals. This point is illustrated perfectly when looking at the fascinating historical photos below that were able to be captured. All of these images are powerful and thought provoking, we want to warn readers that there are some images viewers may find upsetting. Take a look!
