Many Chinese were not happy with the growing Western influence, so they started the Boxer Rebellion.

Explanation:

The Boxer Rebellion was a popular anti-Christian and anti-Western uprising that occurred in virtually every province in northern China between the late 1899s and the early 1900s.

The Boxer Rebellion happened during the Qing Dynasty, with the aim of expelling foreigners from the Chinese territories. This rebellion was counted on the covert support of the local authorities and the Empress Tzu-Hsi herself.

At first, the Boxer Rebellion was limited to small acts of sabotage against the symbols of Western power (such as telegraph lines or railroads, for example), but in a short time the uprising became more aggressive and began to assassinate Christian missionaries and converts, as well as European citizens, including members of diplomacy, depredating their homes and establishments. As a balance of war, we had more than 230 casualties among foreigners and thousands among Chinese Christians.

the northwest ordinance of 1787 guaranteed basic rights for settlers and banned slavery there.
