Tian'anmen Square (天安门广场) in Beijing has been the site of several major events in Chinese history. The most internationally known is the 1989 Tiananmen Square protests and massacre:
- April–June 1989: Following the death of reformist Communist Party official Hu Yaobang, students and citizens gathered in Tiananmen Square to demand political reform, freedom of speech, freedom of the press, and an end to corruption. The protests grew to involve hundreds of thousands of people and spread to other cities.
- June 3–4, 1989: The Chinese government declared martial law and sent the People's Liberation Army with tanks and troops to clear the square. Soldiers opened fire on unarmed civilians. The exact death toll has never been officially disclosed; estimates range from several hundred to several thousand killed, with many more wounded.
- Aftermath: The government imposed a strict censorship regime — public discussion, commemoration, and media coverage of the event are banned in mainland China to this day. The iconic "Tank Man" photo, showing a lone civilian blocking a column of tanks, became a global symbol of the crackdown.
Other notable events at Tiananmen Square include the May Fourth Movement (1919), the founding of the People's Republic of China proclaimed there on October 1, 1949, and protests during the Cultural Revolution.
