Did the Tiananmen Square protests and crackdown happen in 1989?

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

The student-led demonstrations began in mid-April of 1989 (triggered by the death of pro-reform leader Hu Yaobang) and grew to include millions of citizens calling for democracy, free speech, and government accountability. The protests ended when the Chinese government cleared the square by force during the night of June 3 and the morning of June 4, 1989, using military troops and tanks.
