How the cast system and untouchability caused the sad death
Answers
Untouchability is believed to have been first mentioned in Dharmashastra, according to the religious Hindu text, untouchables were not considered a part of the varna system. Therefore, they were not treated like the savarnas (Brahmins, Kshatriyas, Vaishyas and Shudras).
Untouchability has been outlawed in India, Nepal and Pakistan. However, "untouchability" has not been legally defined.[citation needed] The origin of untouchability and its historicity are still debated. B. R. Ambedkar believed that untouchability has existed at least as far back as 400 AD. A recent study of a sample of households in India concludes that "Notwithstanding the likelihood of under-reporting of the practice of untouchability, 70 percent of the population reported not indulging in this practice. This is an encouraging sign."
