Tiananmen Square Massacre of June 4, 1989, part of the Tiananmen Square protests, a series of demonstrations in and near Tiananmen Square led by labor activists, students, and intellectuals.
While the protests lacked a unified cause or leadership, participants were generally against the authoritarianism and economic policies of the ruling Chinese Communist Party and voiced calls for democratic reform within the structure of the government.
A BBC report live from the event back in '89. Worth watching.
The government said hundreds were killed. Others say thousands of innocent protesters were killed as the army fired indiscrimintantly into the crowd. One report says up to 7,000 people were killed. Kind of puts a different perspective on the host nation.
