It was initiated by the Militia United in Righteousness (Yihetuan), known in English as the "Boxers", for many of their members had been practitioners of the martial arts, such as boxing . They were motivated by proto - nationalist sentiments and opposition to Western colonialism and associated Christian missionary activity . </P> <P> The uprising took place against a background of severe drought and the disruption caused by the growth of foreign spheres of influence . After several months of growing violence against both the foreign and Christian presence in Shandong and the North China plain 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 . In response to reports of an armed invasion to lift the siege, the initially hesitant Empress Dowager Cixi supported the Boxers and on June 21 issued an Imperial Decree declaring war on the foreign powers . Diplomats, foreign civilians and soldiers as well as Chinese Christians in the Legation Quarter were placed under siege by the Imperial Army of China and the Boxers for 55 days . </P>
