The Manchu Restoration or Dingsi Restoration (), also known as Zhang Xun Restoration (), or Xuantong Restoration (), was an attempt to restore the Chinese monarchy by General Zhang Xun, whose army seized Beijing and briefly reinstalled the last emperor of the Qing dynasty, Puyi, to the throne. The restoration lasted just shy of two weeks, from July 1, 1917 to July 12, 1917, and was quickly reversed by Republican troops. Despite the uprising's popular name ("Manchu Restoration"), almost all putschists were ethnic Han. Although the Qing dynasty was overthrown in 1912, many people in China wished for its restoration. Ethnic Manchus and Mongols believed that they were discriminated against by China's new Republican government, and restorationism consequently became popular among these ethnic groups. The Qing also enjoyed support among sections of the Han Chinese population as well, such as in Northeastern China. Many were disappointed about the Republican government's inability to solve China's problems. Finally, there were numerous reactionaries and disempowered ex-Qing officials who conspired to overthrow the Republic. As a result, pro-Qing restorationist groups, most notably the Royalist Party, remained an underrepresented, but powerful factor in Chinese politics during the 1910s. Several royalist uprisings were launched, but all failed. The confrontation between President Li Yuanhong and Premier Duan Qirui about whether to join the Allied Powers in World War I and declare war on Germany led to political unrest in the capital Beijing in the spring of 1917. The military governors left Beijing after Duan Qirui's dismissal as Premier. They gathered in Tianjin, calling on the troops from the provinces to rebel against Li and take the capital, despite the opposition of the navy and the southern provinces. In response, on June 7, 1917, Li requested that General Zhang Xun mediate the situation. General Zhang demanded that parliament be dissolved, which Li considered unconstitutional.
