Who did the boxers hate in chinese and why ?

Thus the Boxer Uprising was not a rebellion against the government but instead was directed entirely against foreigners. The Boxers resented the Chinese Christian converts as much as they did the foreigners themselves. Attacks against missionaries and Chinese Christians commenced in later 1899.

hope i helped :)

The Boxer Rebellion, Boxer Uprising or Yihetuan Movement, was an armed and violent xenophobic, anti-Christian, and anti-imperialist insurrection in China between 1899 and 1901, towards the end of the Qing dynasty. They hated the Christian people there and therefor went there to take over.
