Caste system in Kerala
The caste system in Kerala differed from that found in the rest of India. While the Indian caste system generally modeled the four-fold division of society into Brahmins, Kshatriyas, Vaishyas and Shudras, in Kerala, the Nambudiri Brahmins formed the priestly class and only rarely recognized anyone else as being other than Shudra or untouchables, the latter being outside the caste system entirely.
