The Boxer Rebellion ended with the signing of the Boxer Protocol on September 7, 1901.
The rebellion was between the Qing Empire and the Eight-Nation Alliance which included France, United States, Italy, Germany, Austria-Hungary, Japan, Russia, and the British Empire. The Qing Empire was taken over when they lost Beijing, so they made an agreement to destroy the fortifications set up in Beijing by the allies. What the other nations got was mostly money to repair what had been destroyed.
