June 4 marks the anniversary of the Tiananmen Square protest which in 1989 saw student-led demonstrations against the Communist government over several months in Beijing. The crackdown itself became known as the Tiananmen Square Massacre after China's leaders ordered the military to enforce martial law by sending troops in to remove the demonstrators. An unconfirmed number of unarmed civilians were killed in the crackdown. Estimated death toll goes from several hundred to several thousand.
