The proponents of the Andhra origin theory include S. Krishnaswami Aiyangar and K. A. Nilakanta Sastri. They believe that Pallavas were originally feudatories of the Satavahanas in the south-eastern part of their empire who became independent when the Satavahana power declined. They are seen to be "strangers to the Tamil country", unrelated to the ancient lines of Cheras, Pandyas and Cholas. Since Simhavarman's grant bears no regal titles, they believe that he might have been a subsidiary to the Andhra Ikshvakus who were in power in "Andhradesa" at that time. In the following half-century, the Pallavas became independent and expanded up to Kanchi.
