making the brahmin elite angry was a good way to get a rebellion.Both left the caste system completely untouched, and it remains as it was before Islamic invasions began.
The invaders were able to ban so many things like Sati, temple prostitution, breast tax, etc. then why not caste system?
Did the Muslim/British rulers think there would be revolt if the ones at the top of the hierarchy lost all their privileges?
It's a pity that more than a billion Indians lost their only chance to break free of their lowly caste status.
