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 student-led protests began in mid-April 1989 (triggered by the death of former Communist Party leader Hu Yaobang, a reformer) and grew into a massive national movement calling for free speech, democracy, and government accountability. The protests culminated on the night of June 3 and the morning of June 4, 1989, when the Chinese government sent in the military to forcibly clear the square, resulting in the deaths of hundreds, possibly thousands, of demonstrators and civilians.
