The Danavas in Vedic mythology were a race of the Asuras. The Danavas were the sons of Danu, who in turn was a daughter of Daksha. They revolted against the gods under the leadership of Bali and others, but were defeated. In the Rig Veda, nearly all the demons described as being defeated by the Devas are Danavas. After their defeat, the Danavas were cast into the deepest oceans and locked there forever by Indra, or sometimes Rudra. Some argue for an historical basis for the Vedic stories, and that the Danavas, and other defeated beings (Rakshasas, Gandharvas, Nagas, et cetera) were non-Aryan tribes. This is supported by non-Vedic legends and mythologies, for example Naga legends. The Danavas in the Mahabharata have been identified with the Ksatriya kings with an associated date of about 3,200 BCE.
