The struggle between Sanskrit and Tamil which started during the times of Tamil grammarian Tholkappiyar [865 B.C] triggered a grammatical rule to eschew Sanskrit letters. This rule enunciated by Tholkappiyar is the starting point of Dravidian movement says Dr. S.Rajendiran in his Doctorate thesis “ Tamizh Kavithaiyil Dravida Iyakathin Takkam”. Even during the Sangam age we can find the Aryan influence and infiltration into literary texts corrupting the original version. It is known as Idaiserugal. But only in the Pallava period Aryan influence got entrenched deeply. Separate housing colonies for Aryans thereby legitimizing the caste system led to the upward mobility in social ladder of the Aryan peoples. Dr.K.K.Pillai who wrote a book “ The Caste System In Tamil Nadu” holds the above said view.
The Pallavas imposed taxes on agriculturalists and traders but exempted the Aryans. Sekkukaranam [Tax for oil extraction] Thattarakaranam [Tax on Goldsmiths] Paraikaranam [Tax on Musicians] were professional taxes, which Brahmins need not pay. This is revealed by the reports of the Archaeological Survey of India E.I. Vol XXXVI.No.20. pp 144-163.
