Student-led demonstrations occurred in Tiananmen Square, Beijing from April 15 to June 4, 1989. The protests, part of a broader national democracy movement, involved students including leaders Chai Ling and Wang Dan. On June 4, the Chinese government under Deng Xiaoping and Premier Li Peng declared martial law and deployed People's Liberation Army troops with tanks and assault rifles to suppress the demonstrations. Troops fired on protesters and civilians attempting to block military advances. Estimates suggest several hundred to several thousand deaths occurred, with thousands more wounded.
