The Tiananmen Square Massacre refers to a violent crackdown on pro-democracy protesters in Beijing, China, that occurred in June 1989. Thousands of students and citizens gathered in Tiananmen Square to demand political reform, freedom of speech, and other democratic rights. The Chinese government declared martial law and deployed troops to suppress the demonstrations. On June 3-4, the military used tanks and armed soldiers to clear the square, resulting in a significant number of casualties. Estimates of the death toll vary widely, with some sources suggesting hundreds to thousands of people were killed. The event remains a sensitive and censored topic in China.
