Political map of East Asia and the Western Pacific 16 June 1900 (Boxer Rebellion): In response to the growing foreign domination of China (Century of Humiliation), the isolationist Yihetuan movement -  known in the west as Boxers - rose up and began attacking and killing  foreigners and Chinese Christians within the country (Boxer Rebellion). In January 1900, the Great Powers demanded that  China suppress the Boxers, but many Chinese officials were sympathetic to  their cause. Facing increasing Boxer activity, an alliance of eight nations (Eight Nation Alliance) invaded northern China.
