Did the Tiananmen Square protests and crackdown happen in 1989?

Yes, the Tiananmen Square protests and the subsequent government crackdown (also known as the June Fourth Incident or Tiananmen Square massacre) occurred in 1989.[1]

Student-led demonstrations began in April 1989 in Beijing’s Tiananmen Square (and spread to other cities), calling for political reform, an end to corruption, and greater freedoms. They continued for weeks, involving large numbers of students, workers, and others. Martial law was declared in May, and on the night of June 3–4, 1989, the Chinese military advanced on the square, using lethal force to clear protesters, resulting in hundreds (and by some estimates more) killed and many injured.[2]

This is a well-documented historical event confirmed by numerous contemporary reports and historical accounts.
