1989 Tiananmen Square protests and massacre
The Tiananmen Square protests, known within China as the June Fourth Incident, were student-led demonstrations held in Tiananmen Square in Beijing, China, lasting from 15 April to 4 June 1989. After weeks of unsuccessful attempts between the demonstrators and the Chinese government to find a peaceful resolution, the Chinese government deployed troops to occupy the square on the night of 3 June in what is referred to as the Tiananmen Square massacre.
