B. R. Ambedkar

B. R. Ambedkar was born in a caste that was classified as untouchable, became a leader of human rights campaigns in India, a prolific writer, and a key person in drafting modern India's constitution in the 1940s. He wrote extensively on discrimination, trauma and what he saw as the tragic effects of the caste system in India. He believed that the caste system originated in the practice of endogamy and that it spread through imitation by other groups. He wrote that initially, Brahmins, Kshatriyas, Vaishyas and Shudras existed as classes whose choice of occupation was not restricted by birth and in which exogamy was prevalent. Brahmins then began to practise endogamy and enclosed themselves, hence Ambedkar defines caste as "enclosed class". He believed that traditions such as sati, enforced widowhood and child marriage developed from the need to reinforce endogamy and Shastras were used to glorify these practices so that they are observed without being questioned. Later, other caste groups imitated these customs. However, although Ambedkar uses the approach of psychologist Gabriel Tarde to indicate how the caste system spread, he also explains that Brahmins or Manu cannot be blamed for the origin of the caste system and he discredits theories which trace the origin of caste system in races.
