Tiananmen in the context of "Red August"

The May Fourth Movement was a Chinese cultural and anti-imperialist political movement which grew out of student protests in Beijing on May 4, 1919. Students gathered in front of Tiananmen to protest the Chinese government's weak response to the Treaty of Versailles decision to allow the Empire of Japan to retain territories in Shandong that had been surrendered by the German Empire after the Siege of Tsingtao in 1914. The demonstrations sparked nationwide protests and spurred an upsurge in Chinese nationalism, a shift towards political mobilization, away from cultural activities, and a move towards a populist base, away from traditional intellectual and political elites.

The May Fourth demonstrations marked a turning point in a broader anti-traditional New Culture Movement (1915–1921) that sought to replace traditional Confucian values and was itself a continuation of late Qing reforms. Even after 1919, these educated "new youths" still defined their role with a traditional model in which the educated elite took responsibility for both cultural and political affairs. They opposed traditional culture but looked abroad for cosmopolitan inspiration in the name of nationalism and were an overwhelmingly urban movement that espoused populism in an overwhelmingly rural country. Many political and social leaders of the next five decades emerged at this time, including those of the Chinese Communist Party (CCP).

Tiananmen Square or Tian'anmen Square (/ˈtjɛnənmən/) is a city square in the city center of Beijing, China, named after the Tiananmen ("Gate of Heavenly Peace") located to its north, which separates it from the Forbidden City imperial palace complex. The square holds the Monument to the People's Heroes, the Great Hall of the People, the National Museum of China, and the Mausoleum of Mao Zedong. They were inscribed in the UNESCO World Heritage Sites in 2024 as a part of the Beijing Central Axis.

Chairman Mao Zedong proclaimed the founding of the People's Republic of China in the square on October 1, 1949; the anniversary of this event is still observed there. The size of Tiananmen Square is 765 × 282 meters (215,730 m or 53.31 acres). It has great cultural significance as it was the site of several important events in Chinese history.

On 1 October 1949 CCP chairman Mao Zedong proclaimed the People's Republic of China (PRC) from atop Tiananmen, after a near complete victory (1949) by the Chinese Communist Party (CCP) in the Chinese Civil War. The PRC is the most recent political entity to govern mainland China, preceded by the Republic of China (ROC; 1912–1949) and thousands of years of monarchical dynasties. The paramount leaders have been Mao Zedong (1949–1976); Hua Guofeng (1976–1978); Deng Xiaoping (1978–1989); Jiang Zemin (1989–2002); Hu Jintao (2002–2012); and Xi Jinping (2012 to present).

The origins of the People's Republic can be traced to the Chinese Soviet Republic that was proclaimed in 1931 in Ruijin (Jui-chin), Jiangxi (Kiangsi), with the backing of the All-Union Communist Party in the Soviet Union in the midst of the Chinese Civil War against the Nationalist government only to dissolve in 1937.

The Imperial City (Chinese: 北京皇城; pinyin: Běijīng Huángchéng; lit. 'Beijing Imperial City') is a section of the city of Beijing in the Ming and Qing dynasties, with the Forbidden City at its center. It refers to the collection of gardens, shrines, and other service areas between the Forbidden City and the Inner City of ancient Beijing. The Imperial City was surrounded by a wall and accessed through seven gates and it includes historical places such as the Forbidden City, Tiananmen, Zhongnanhai, Beihai Park, Zhongshan Park, Jingshan, Imperial Ancestral Temple, and Xiancantan.
