The People's Liberation Army suppressed the Tiananmen Square protests in Beijing, leaving hundreds of people dead and wounded.

The People's Liberation Army (PLA) is the military of the Chinese Communist Party (CCP) and the People's Republic of China (PRC). It consists of four services—Ground Force, Navy, Air Force, and Rocket Force—and four arms—Aerospace Force, Cyberspace Force, Information Support Force, and Joint Logistics Support Force. It is led by the Central Military Commission (CMC) with its chairman as commander-in-chief.

During the 1989 Tiananmen Square protests and massacre in Beijing, the People's Liberation Army (PLA) played a decisive role in enforcing martial law, using force to suppress the demonstrations in the city. The killings of protestors in Beijing continue to taint the legacies of the party elders, led by the military leader Deng Xiaoping, and weigh on the generation of leaders whose careers advanced as their more moderate colleagues were purged or sidelined at the time. Within China, the role of the military in 1989 remains a subject of private discussion within the ranks of the party leadership and PLA.

The Tiananmen Square protests, known within China as the June Fourth Incident, were student-led demonstrations held in Tiananmen Square in Beijing, China, lasting from 15 April to 4 June 1989. After weeks of unsuccessful attempts between the demonstrators and the Chinese government to find a peaceful resolution, the Chinese government deployed troops to occupy the square on the night of 3 June in what is referred to as the Tiananmen Square massacre. The events are sometimes called the '89 Democracy Movement, the Tiananmen Square Incident, or the Tiananmen uprising.

Beijing, previously romanized as Peking, is the capital city of China. With more than 22 million residents, it is the world's most populous national capital city as well as China's second largest city by urban area after Shanghai. It is located in Northern China, and is governed as a municipality under the direct administration of the State Council with 16 urban, suburban, and rural districts. Beijing is mostly surrounded by Hebei Province and neighbors Tianjin to the southeast; together, the three divisions form the Jing-Jin-Ji cluster.
