According to wikipedia, the Boxers were the major reason that the foreign powers did not colonize China
"the great powers stopped short of finally colonizing China. From the Boxer rebellions, they learned that the best way to deal with China was through the Chinese dynasty, instead of direct dealing with the Chinese people (as a saying "The people are afraid of officials, the officials are afraid of foreigners, and the foreigners are afraid of the people" (老百姓怕官,官怕洋鬼子,洋鬼子怕老百姓))."
