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 protests began in mid-April 1989 in Beijing’s Tiananmen Square (and spread to other cities), initially mourning the death of reformist official Hu Yaobang and calling for political reform, anti-corruption measures, free speech, and other democratic changes. They grew into a large pro-democracy movement involving students, workers, and others.
