Which uprising in China aimed to expel foreign influence, including that of the United States?

The Boxer Rebellion, which occurred between 1899 and 1901, specifically aimed to expel foreign influence in China, targeting foreign nationals and Chinese Christians who were perceived as promoting Western ideals and cultures. The movement was led by the "Boxers," a group that opposed foreign imperialism and sought to restore Chinese sovereignty. Their actions included violent uprisings against foreign embassies and missionaries, symbolizing the frustration and anger at foreign exploitation and control over China's affairs.

In the context of American imperialism, the Boxer Rebellion is significant as it vividly illustrates the resistance faced by foreign powers, including the United States, in their efforts to exert influence over China. The rebellion was ultimately suppressed by an international coalition, including American forces, which reinforced the presence of Western powers in China rather than diminishing it.

The other events listed did not primarily focus on expelling foreign influence. The Taiping Rebellion was primarily a civil war against the Qing dynasty rather than a movement against foreign powers. The Opium Wars were conflicts initiated by foreign powers to protect their trade interests in opium rather than nationalist uprisings against foreign control. The May Fourth Movement emerged primarily from intellectual and cultural frustrations rather than direct violence aimed at repelling foreign influence.
