Reading a bit about late imperial Chinese history recently has got me paticularly interested in the Boxer rebellion. The Boxers aimed to removed foreign (more specifically western) influence from China. As far as I understand, Cixi supported the Boxers at first as a way to strengthen Chinas independence, but turned on them as it appeared that their cause was lost.
But what if instead of turning against them, she continued to support them with the Chinese army? Would they have a chance of defeating the international force sent to Beijing? And what would the western reaction be to the defeat of their "peacekeeping" force?
