The Boxer Rebellion (拳亂), Boxer Uprising, or Yihetuan Movement (義和團運動) was an anti-imperialist, anti-foreign, and anti-Christian uprising that took place in China between 1899 and 1901, toward the end of the Qing dynasty. It was initiated by the Militia United in Righteousness (Yìhéquán), known in English as the Boxers because many of their members had been practitioners of Chinese martial arts, also referred to in the west as Chinese Boxing. The uprising took place against a background that included severe drought and disruption caused by the growth of foreign spheres of influence in China. After several months of growing violence in Shandong and the North China Plain against the foreign and Christian presence in June 1900, Boxer fighters, convinced they were invulnerable to foreign weapons, converged on Beijing with the slogan Support the Qing government and exterminate the foreigners. Foreigners and Chinese Christians sought refuge in the Legation Quarter.
