The ‘Unknown Rebel’ was the nickname given to an anonymous man who became internationally famous for being photographed standing before a line of tanks during the Tiananmen Square uprising of 1989 in China. The photo was taken by Jeff Widener. The man seems to be stopping the advance of the tanks and the image has been around the world.
In China, the picture was used by the government as a symbol of compassion the soldiers of the People's Liberation Army felt towards the Chinese people and their desire to protect them. Despite orders to advance, the tank driver refused to do so.
