Caste system developed on rigid lines post Mauryan period, especially after the establishment of Sunga dynasty by Pushyamitra Sunga( 184 BC). This dynasty was an hot patron of ‘ Brahminism ’. Through Manusmriti, Brahmins formerly again succeeded in organizing the supremacy and assessed severe restrictions on the Sudras. Manusmriti mentioned that, ‘ the Sudra, who insults a doubly- born man, shall have his lingo cut out ’. According to one long- held proposition about the origins of South Asia's estate system, Aryans from central Asia raided South Asia and introduced the estate system as a means of controlling the original populations. The Aryans defined crucial places in society, also assigned groups of people to them. individualities were born into, worked, married, ate, and failed within those groups. There was no socialmobility.But 20th- century education has completely rebutted this proposition. utmost scholars believe that there was no Aryan irruption from the north. In fact, some indeed believe that the Aryans — if they did live — actually began in South Asia and spread from there to Europe. Anyhow of who the Aryans were or where they lived, it's generally agreed that they didn't single- handedly produce South Asia's estate system. therefore, it has been insolvable to determine the exact origins of the estate system in South Asia. In the midst of the debate, only one thing is certain South Asia's estate system has been around for several glories and, until the alternate half of the 20th century, has changed veritably little during all of that time. In ancient India, the ranked occupational groups were appertained to as varnas, and the heritable occupational groups within the varnas were known as jatis. numerous have incontinently assumed that credited social groups and rules proscribing intermarriage among the groups signify the actuality of a racist culture. But this supposition is false. Varnas are not ethnical groups but rather classes. Four varna orders were constructed to organize society along profitable and occupational lines. Spiritual leaders and preceptors were called Brahmins. soldiers and nobility were called Kshatriyas. merchandisers and directors were called Vaishyas. sloggers were called Sudras. The Untouchables In addition to the varnas, there is a fifth class in Hinduism. It encompassed rejects who, literally, did all the dirty work. They were appertained to as" rejects" because they carried out the miserable tasks associated with complaint and pollution, similar as drawing up after sepultures, dealing with sewage, and working with beast skin. Brahmins were considered the personification of chastity, and untouchables the personification of pollution. Physical contact between the two groups was absolutely banned. Brahmins stuck so explosively to this rule that they felt obliged to bathe if indeed the shadow of an untouchable fell across them. floundering against Tradition Although the political and social force of the estate system has not faded fully, the Indian government has officially outlawed estate demarcation and made wide reforms. Particularly through the sweats of Indian chauvinists similar as Mohandas Gandhi, rules precluding social mobility andcross-caste mingling have been loosened. Gandhi renamed the rejects Harijans, which means" the people of God." espoused in 1949, the Indian Constitution handed a legal frame for the liberation of rejects and for the equivalency of all citizens. In recent times, the Rejects have come a politically active group and have espoused for themselves the name Dalits, which means" those who have been broken."
