Did the Tiananmen Square protests and crackdown happen in 1989?

Yes, the Tiananmen Square protests and the subsequent military crackdown took place in 1989.

The timeline of the key events is as follows:

•The Protests Begin (April 1989): The demonstrations began in mid-April 1989, sparked by the death of Hu Yaobang, a former leader of the Chinese Communist Party who had been seen as a proponent of democratic and economic reforms. Students and citizens gathered in Beijing's Tiananmen Square to mourn him, which quickly evolved into a larger movement calling for political reform, freedom of speech, an end to corruption, and greater individual rights.

•The Crackdown (June 3–4, 1989): After weeks of demonstrations that drew massive crowds and spread to other Chinese cities, the Chinese government declared martial law. On the night of June 3 and the early morning of June 4, 1989, the military advanced into Beijing with troops and tanks, opening fire on protesters and bystanders to clear the square.

Because of the date of the final crackdown, the event is also commonly referred to in China as the "June Fourth Incident" (or simply "June Fourth").
