Tank Man (also known as the Unknown Protester or Unknown Rebel) is the nickname of an unidentified Chinese man who stood in front of a column of tanks leaving Tiananmen Square on June 5, 1989, the morning after the Chinese military had suppressed the Tiananmen Square protests by force. 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 smuggled out to a worldwide audience. Internationally, it is considered one of the most iconic images of all time. Inside China, the image and the events leading up are subject to heavy state censorship, and as a result they are being forgotten.
There is no reliable information about the identity or fate of the man,
