Ever since their invention, cameras have allowed us to capture snapshots of some of recent history’s most important moments. Whether it’s war and strife, famous entertainers, or other monumental human milestones, it’s all been captured on film.

Increasingly, historical photos remind us of how far we’ve come as a society. Sometimes, as with these 20 images, they even have the power to give us a new perspective on that which we thought we already knew!
