The 1989 Tiananmen Square protests, commonly known in mainland China as the June Fourth Incident(Chinese: 六四事件, liùsì shìjiàn), were student-led demonstrations in Beijing (the capital of the People's Republic of China) in 1989. More broadly, it refers to the popular national movement inspired by the Beijing protests during that period, sometimes called the '89 Democracy Movement (Chinese: 八九民运, bājiǔ mínyùn). The protests were forcibly suppressed after Chinese Premier Li Peng declared martial law. In what became known in the West as the Tiananmen Square Massacre, troops with assault rifles and tanks fired at the demonstrators trying to block the military's advance towards Tiananmen Square. The number of civilian deaths has been estimated variously from 180 to 10,454.
