The Boxer Movement or Boxer Rebellion, which occurred in China from November 1899 to September 7, 1901, was an uprising by members of the Chinese Society of Right and Harmonious Fists against foreign influence in areas such as trade, politics, religion and technology that occurred in China during the final years of the Manchu rule (Qing Dynasty). The members of the Society of Right and Harmonious Fists were simply called "boxers" by the Westerners due to the martial arts and calisthenics they practiced. The uprising began as an anti-foreign, anti-imperialist peasant-based movement in northern China. They attacked foreigners who were building railroads and violating Feng shui, as well as Christians, who were held responsible for the foreign domination of China. In June 1900, the Boxers invaded Beijing and killed 230 non-Chinese. Tens of thousands of Chinese Christians, Catholic and Protestant alike, were killed mostly in Shandong and Shanxi Provinces as part of the uprising. The government of Empress Dowager Cixi was not helpful, and diplomats, foreign civilians, soldiers and some Chinese Christians retreated to the legation quarter where they held out for fifty-five days until a multinational coalition rushed 20,000 troops to their rescue. The Chinese government was forced to indemnify the victims and make many additional concessions. Subsequent reforms implemented after the crisis of 1900 laid the foundation for the end of the Qing Dynasty and the establishment of the modern Chinese Republic.
