Tiridates was a usurper who challenged Phraates IV for the Parthian kingship. Initially successful, he eventually was forced to seek refuge among the Romans. He brought with him a captive son of Phraates, who Augustus later used to exchange for the Roman legionary standards captured from the defeat of the legions under Crassus at Carrhae in 53 BC. He returned a few years later for another attempt, but was likely killed as his name disappears from the historical record.
