Did the Tiananmen Square protests and crackdown happen in 1989?

Yes, the Tiananmen Square protests and crackdown took place in 1989. Student-led demonstrations calling for political reform and greater freedoms centered in Beijing's Tiananmen Square beginning in April 1989, and the Chinese government declared martial law and sent in troops and tanks, violently suppressing the protests on June 3–4, 1989. The crackdown resulted in a significant, though still disputed, number of civilian deaths, and it remains one of the most sensitive and heavily censored topics in China to this day.
