A significant event that took place in Tiananmen Square in 1989 was the Tiananmen Square Massacre, a pro-democracy protest led mainly by students. The demonstrators called for political reform, freedom of speech, and an end to corruption. The Chinese government declared martial law, and on June 3-4, the military violently suppressed protests, resulting in a large, though still unknown, number of casualties. The incident drew global condemnation and remains a sensitive and censored topic in China, emblematic of the struggle for human rights.
