What is the general name of the social groups into which Indian society has historically been divided?

Player Jellybean, yes I agree with you 100%, it's like the Taliban and their treatment of women. it should be outlawed! in my opinion!

Sage Anshu, yeah blame the Brits here too.

The caste system that we see today in India is only in existence from last 250-300 years i.e. after the Britishers invaded India. The ancient Varna System was based on the work and had no arrangements like this modern system which was kinda introduced by British and then abused by the political parties of India to reserve their vote banks.
