full_question: One ruler by this name stabbed himself in the company of his eunuch Drastamat after being thrown in jail trying to negotiate peace with Shapur II. Another ruler by this name, also known as Artabanus, ceased minting coins after a loss to Antiochus III at the Battle of Mount Labus, which allowed Antiochus to occupy Hecatompylos. The numerically second ruler of this name was succeeded by his son Pap, and built several hospitals and monasteries with the help of his chamberlain St. Nerses the Great. The final Roman client ruler of Armenia had this name, as did a king credited with founding the city of Nisa. The revolt of the governor Andragoras allowed that ruler of this name to lead the Parni tribe in occupying Hyrcania. The kingdom founded by that man later employed the general Surena, who poured molten gold down the throat of Crassus after defeating him at Carrhae. For 10 points, identify that man who was the namesake of a dynasty as the first ruler of the Parthian kingdom.
