This thread (which I'm pinning) is for images, videos, articles and general discussions of history/pre-history.
It can be used for small/minor contributions, which perhaps don't warrant their own entire thread.
Let me start by posting this famous photo, taken exactly 26 years ago:
https://en.wikipedia.org/wiki/Tank_Man
"A man who stood in front of a column of tanks on June 5, 1989, the morning after the Chinese military had suppressed the Tiananmen Square protests of 1989 by force, became known as the Tank Man or Unknown Protester. As the lead tank maneuvered to pass by the man, he repeatedly shifted his position in order to obstruct the tank's attempted path around him. The incident was filmed and seen worldwide. Currently, there is no reliable information about the identity or fate of the tank man."
