Fang Lizhi was a Chinese astrophysicist, vice-president of the University of Science and Technology of China, and activist whose liberal ideas inspired the pro-democracy student movement of 1986–87 and, finally, the Tiananmen Square protests of 1989. Because of his activism, he was expelled from the Chinese Communist Party in January 1987. For his work, Fang was a recipient of the Robert F Kennedy Human Rights Award in 1989, given each year. He was elected an academician of the Chinese Academy of Sciences in 1980, but his position was revoked after 1989.

The Tiananmen Square protests, known in China as the June Fourth Incident, were student-led demonstrations held in Tiananmen Square, 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 declared martial law on the night of 3 June and deployed troops to occupy the square 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.
