Did the Tiananmen Square protests and crackdown happen in 1989?

Yes, the Tiananmen Square protests and crackdown happened in 1989.

The protests began in April 1989, largely sparked by the death of reformist Communist Party leader Hu Yaobang, and grew into weeks of demonstrations centered in Beijing's Tiananmen Square, calling for political reform, free speech, and an end to corruption. The movement was eventually crushed when the Chinese government declared martial law and sent in military troops and tanks, resulting in a violent crackdown on the night of June 3–4, 1989. The exact death toll from the crackdown has never been officially confirmed and remains disputed, with estimates ranging from several hundred to possibly over a thousand people killed.
