In the "Vayu Purana", Manu (the patriarch of ancient India) had nine sons; Ikshvaku, the eldest, founded the Suryavanshi dynasty and ruled from Ayodhya at the beginning of the Treta Yuga. He had 100 sons; the eldest was Vikushi, who succeeded his father as the ruler of Ayodhya. Fifty of Vikushi's brothers founded small principalities in North India, and forty-eight founded kingdoms in the south. In the Dharmamrita, during the lifetime of the 12th "tirthankara", Yasodhara (an Ikshvaku prince from the kingdom of Anga) went to Vengi. The prince was so impressed with the region's beauty and fertility that he made it his home and founded the city of Pratipalapura (present-day Bhattiprolu).
