The Tiananmen Square protests in 1989 culminated in a significant demonstration for democracy, with thousands of students and citizens advocating for political reform in China. On June 3-4, the Chinese government declared martial law and deploys troops and tanks to quell the protests, leading to a violent crackdown. Estimates of casualties vary, with figures ranging from hundreds to thousands of deaths. This brutal response drew international condemnation, highlighting China's human rights abuses. The event remains a sensitive topic in China and continues to serve as a symbol of the struggle for freedom and democracy in authoritarian regimes.
