Final answer:
The Boxer Rebellion, which occurred in China involving a secret martial arts society known as the 'Boxers', was a true historical event aimed at expelling foreign influence from China and marked by significant violence against foreigners and Christians, before being suppressed by an international force.
Step-by-step explanation:
The statement that the Boxer Rebellion occurred in China and involved a secret Chinese martial arts society is true.
The Boxer Rebellion, which lasted from 1899 to 1901, was an anti-colonial, anti-Christian uprising by a group known as the Society of the Righteous and Harmonious Fists, or "Boxers."
These revolutionaries aimed to purge China of foreign influence and believed their martial arts training could make them immune to western weapons.
Their insurgency led to the death of Christian missionaries, Chinese Christians, foreign nationals, and resulted in widespread property destruction.
In response, an eight-nation alliance, including troops from Europe, the United States, and Japan, intervened with 20,000 troops to quash the rebellion in Beijing, leading to severe repercussions for China, including a huge financial indemnity.
