The Tiananmen Square protests, known in Chinese as the June Fourth Incident were student-led demonstrations held in Tiananmen Square, Beijing, China, lasting from 15 April to 4 June, 1989. On the night of 3 June, after weeks of attempts to resolve the conflict peacefully, including negotiations from both sides, the Chinese government declared martial law, and deployed troops to occupy the Square in what is often referred to as the Tiananmen Square massacre. The events are sometimes called the '89 Democracy Movement, the Tiananmen Square Incident, or the Tiananmen uprising. The protests were precipitated by the death of pro-reform Chinese Communist Party (CCP) general secretary Hu Yaobang in April 1989 amid the backdrop of rapid economic development and social change in post-Mao China, reflecting anxieties among the people and political elite about the country's future. The reforms of the 1980s had led to a nascent market economy that benefited some people but seriously disadvantaged others, and the one-party political system also faced a challenge to its legitimacy. Common grievances at the time included inflation, corruption, limited preparedness of graduates for the new economy, and restrictions on political participation. Although they were highly disorganized and their goals varied, the students called for greater accountability, constitutional due process, democracy, freedom of the press, and freedom of speech. Workers' protests were generally focused on inflation and the erosion of welfare. These groups united around anti-corruption demands, adjusting economic policies, and protecting social security. At the height of the protests, about one million people assembled in the square. As the protests developed, the authorities responded with both conciliatory and hardline tactics, exposing deep divisions within the party leadership. By May, a student-led hunger strike galvanized support around the country for the demonstrators, and the protests spread to some 400 cities.
