Final answer:
The Chinese government was required to pay indemnity during the Boxer Rebellion (1900-1901), following the intervention of an eight-nation alliance.
Step-by-step explanation:
The Chinese government was forced to pay indemnity during the Boxer Rebellion (1900-1901). This was a significant anti-colonial and anti-Christian uprising, which led to the intervention of an eight-nation alliance including European countries, the United States, and Japan. The foreign troops ultimately suppressed the rebellion in Beijing and imposed a hefty indemnity on the Qing government, amounting to 450 million taels of silver.
