Why where the boxers from the Boxer rebellion called boxers?

Answer 1

The reason the "Boxers" were called Boxers is because during the rebellion the boxers had banners and on the banners was a black closed fist so the people getting attacked thought they were boxers

Answer 2

The term 'Boxer' was what foreigners call this group:

"The Society of Righteous and Harmonious Fists, known by foreigners as the Boxers, or "Yihe Magic Boxing", was a secret society founded in the northern coastal province of Shandong consisting largely of people who had lost their livelihoods due to Imperialism[clarification needed] and natural disasters.[5] The group originated from the Lí sect of the Ba gua religion group.[6] Foreigners came to call the well-trained, athletic young men "Boxers" due to the Martial Arts and calisthenics they practiced."

Answer 3

The Boxers resented foreign influence in Chinese cities. They attacked foreigners as an outlet for that resentment.

Answer 4

The Boxer Rebellion, Boxer Uprising, or Yihetuan Movement was an anti-imperialist, anti-foreign, and anti-Christian uprising in China between 1899 and 1901, towards the end of the Qing dynasty.
