During which conflict did the Boxer Rebellion take place?

The Boxer Rebellion was an anti-foreign uprising that occurred in China between 1899 and 1901. This movement was driven by the "Boxers," a group of Chinese nationalists who opposed foreign influence and the presence of foreign nationals in China. They sought to rid the country of foreign colonial powers and their associated cultures, which they believed were corrupting traditional Chinese society.

The rebellion targeted not only foreigners but also Chinese Christians and others whom the Boxers saw as collaborators. Ultimately, the uprising led to an international military intervention in which eight nations, including the United States, British Empire, France, Germany, and Japan, sent troops to suppress the rebellion and protect their citizens and interests. The conflict culminated in the siege of Beijing and significant violence against both foreigners and Chinese citizens.

In contrast, the other conflicts listed in the options occurred in different historical contexts. World War I and World War II were large-scale global conflicts that involved many nations and took place well after the Boxer Rebellion. The Chinese Civil War, which followed the end of the Boxer Rebellion, was a conflict between the Chinese Nationalist Party (Kuomintang) and the Communist Party of China, with major fighting primarily occurring in the mid-20th century
