This intrusion of kings of Avanti in the records of Magadha is probably to be explained, as in the similar case of the Andhras (p. 318), as the result of a suzerainty successfully asserted by Avanti; and this may have been the outcome of the attack on Ajātaçatru which Pradyota was reported to have been contemplating shortly before the Buddha's death⁵. If so, the supremacy of Avanti, which may have been temporary, was not established until some years after the beginning of Ajātaçatru's reign, and the Pradyotas of the Purāṇas were contemporary with the later Çiçunāgas—Ajātaçatru, Darçaka, and Udāyin.
