Did the Tiananmen Square protests and crackdown happen in 1989?

Yes.

The Tiananmen Square protests took place in Beijing, China, primarily from April to June 1989. Student-led demonstrations calling for political reform, free speech, and an end to corruption occupied Tiananmen Square. On the night of June 3–4, 1989, the Chinese government declared martial law and deployed the People’s Liberation Army to clear the square, resulting in a violent crackdown with significant casualties (estimates of deaths vary widely, from hundreds to thousands, with no official Chinese government figure that matches independent accounts).

This is a well-documented historical event, confirmed by contemporary news reporting, eyewitness accounts, declassified documents, academic histories, and records from multiple governments and organizations.
