why were the soldiers under the Indian rulers unhappy?

Dear student,
The Indian soldiers were happy with Indian rulers but they were unhappy with British rulers because:
 

• They were paid quite low wages. 
• They were discriminated on the basis of caste. 
• The new enfield rifle had a cartridge of pork fat which was required to bitten by them to use it further. This was against the religious beliefs of Muslim soldiers.
