King Ikshvaku was the son of Satyavrata also called Shraddhadeva Manu, the king of Dravida kingdom. According to the Vedas, Ikshvaku was the protector of the five territories of Panchajanah who were non-sacrificing pre-Aryan and non-Aryan people. The Atharvaveda and Brahmanas associate the Ikshvakus with the non-Aryan people, that is they are different from the Vedic Aryans who composed hymns like the Rig Veda. F. E. Pargiter has equated the Ikshvakus with the Dravidian peoples.Ikshvaku and his ancestor Manu are mentioned in the Bhagavata Purana,Citations
