Jayadaman was a Western Kshatrapa ruler, although possibly only a Kshatrapa, rather than a Mahakshatrapa. He was the son of Chastana, and the father of Rudradaman I, but he may have pre-deceased Chastana, and never ruled as supreme ruler of the Western Kshatrapas.''Political history of ancient India'' by Hemchandra Raychaudhuri p.260
/ref> This is suggested by the fact that Chastana and Rudraman I are known from contemporary Indian inscriptions to have ruled jointly. His diminished title may also have been a consequence of the conquests of the Satavahanas over Kshatrapa territory. The coins of Jayadaman were rather crude, only made of copper and square in form.''Malwa through the ages, from the earliest times to 1305 A.D.'' by Kailash Chand Jain p.371
