The Boxer Rebellion, Boxer Uprising or Yihetuan Movement, was an armed and violent, anti-Christian, and anti-imperialist insurrection in China between 1899 and 1901, towards the end of the Qing dynasty.
It was initiated by the Militia United in Righteousness, known in English as the Boxers because many of their members had practiced Chinese martial arts, also referred to in the Western world at the time as Chinese Boxing. Villagers in North China had been building resentment against Christian missionaries and the growth of foreign spheres of influence after the Sino-Japanese War of 1895. In a severe drought, violence and murder spread across Shandong and the North China Plain, targeting foreign property, Christian missionaries and Chinese Christians. 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.
