What events led to the Boxer Rising and why did it fail?

The Boxer nawerant stemmed from the an- cient tradition of popular rebellion, against the regime in power. The I-ho Chuan, which originated as an offshoot of the rebellious Fight Trigrama Society of the Jate eighteenth. century and to: whiou the Boxers belonged, was ane of the many secret societies then flourish- ing in China. Since it was antidynastic in na ture, imperial decrees had ordered its suppres- sion in the early nineteenth century, but it had marvived underground in Shantung and Chikhli.

The Boxers developed a magic art using Taoist sorcery and a prescribed ritual, which they thought would gave them supernatural powers and made then impervious to all sorts of weapons avan foreign Hulleta.

During the late nineteenth century, with the gradual penetration of Western influences and the activities of the foreign missionaries, antiforeigniam was a general sentiment among the Chinese people. As a result, the Boxers added antiforeignism to its original antidynastio ain. Their slogan was "Overthrow the Chingi destroy the foreigners." And antiforeign and anti-missionary activities became an important part of tue movement. In this respect, they were able to win the sympathy of many people, as well as some of the officials, both Locally and up to the very top of the dynasty. In the course of time, this type of official patronage effected a kind of change in the nature of the Boxer movement. It shifted from antidynastic to prodynastio, and its slogan became "Support the Ch'ing; destry the foreigner."

The current economie and political con- ditions also contributed to the revival of the Boxer movement. For example, Yellow Riverfloods. had led to widespread famine in Shantung in1898, and the whole North China Buffered generally from drought. Starved and destitute people were moving about as vagrants and many joined the Boxer movement. In fact, the unrest was wide- spread,

However, such activities led to the protests of the foreign powers which effected the removal of Tu-hsien, His successor, Yuan Shih-kai, proceeded to take actions against the Boxers, checked the movement in Shantung, and drove then to Chihli.

or, the Boxers who had crossed into Chihli continued their antiforeign and anti- missionary activition. Many of the Chinese officials gave them a free hand, and it was obvious that the ExpressƉovager of Ta'u-kai was also sympathetic to the Boxers, In fact, Is'u-hsi anë. many of the officials really believed the Boxers had magic powers and that they might be used as a convenient and reliable. weapon to throw she foreigners out of China, As a result, the Boxer movement came to a high tide in the summer when they were allowed to enter Paking and Tientsin in June.

Keteller, the German ambassador, was short to deaths Chinese Christians were massaared, foreign eatablishments were burnt ; and the Ch'ing dynasty declared war against the foreign powers on June 21.

The foreign powers responded to this with the organization of an international force which, gradually built up to some 20,000 troops. The Boxer forces quickly disintegrated under-attack, and moon the whole of North Chine fell under foreign control. Negotiations for peace then "followed and the Boxer Protocol was finally
