The Boxer Rebellion of 1900. The campaign was caused by the Boxers, a xenophobic movement who carried out a series of attacks on foreign missionaries, merchants and property. The Chinese government did little to remedy the situation, and in June 1900 issued an edict which amounted to support for the Boxers. The foreign legations in the imperial capital Pekin [Beijing] were besieged, and held out for three months despite having a small garrison. The British contingent in the legation guard comprised 82 members of the Royal Marines. An international relief force was organised by seven nations, and in June 1900 the Taku Forts were captured. The force then moved on Pekin, which was relieved in August. Peace was concluded in January 1901.
