In 1900 Britain, the United States, Germany, France, Russia, Japan, Italy and Austria, in order to suppress the Chinese anti-imperialist Yi Ho Tuan Movement (the Boxer Uprising), organized allied forces to wage war on China. These forces captured Tianjin, Beijing, Shanhaiguan and other places. At the same time, Russia sent troops to invade Northeast China. The Qing government begged for a reconciliation and on September 7, 1901, signed the humiliating International Protocol of 1901, by which it accepted all the harsh terms dictated by the imperialist powers.
