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 demonstrations began in April 1989 (triggered in part by the death of former Communist Party leader Hu Yaobang, a reformer) and culminated in a violent crackdown by the Chinese government on June 3–4, 1989, when the military was sent in to clear the square.
