In response to foreign encroachment in China, Chinese nationalists launch the so-called Boxer Rebellion in Peking. Calling themselves I Ho Ch’uan, or the Righteous and Harmonious Fists, the nationalists occupied Peking, killed several foreign officials, and besieged the diplomatic quarter of the city.
The British called the nationalists Boxers because of their martial-arts fighting style. The siege continued until August 14, when an international force featuring British, Russian, American, Japanese, French, and German troops fought their way into Peking and ended the Boxer Rebellion.
In the aftermath, a peace treaty was forced on China’s ruling government, making China effectively a subject nation of the foreign powers.
