Often we think of Herod the Great  in relation to ancient Rome. We understand the king as steadfast in his loyalty to this western imperial power—and rightly so. Herod’s behavior routinely betrayed his Roman interests, and inscriptions attest to and advertise this allegiance by identifying him with such titles as “Friend of the Romans.” It is entirely appropriate then to apply the modern label “Roman client king” to Herod, as scholars have done for so long.
Another view of Herod, however, complicates this picture. Herod was not merely a passive subject of Rome. In fact, if we only view Herod against the Roman backdrop, we risk misunderstanding the circumstances of his rise to power and underestimating his accomplishment. While the Romans were indeed a key source of Herod’s authority, he rose to power and maintained his position through timely manipulations of the contentious geopolitics that defined his day.

Rome was not the undisputed master of the Near East. The empire of Parthia stretched from modern Afghanistan through Iran to the Euphrates River in Iraq, encompassing territories once ruled by Persian kings and then by Alexander the Great  and his successors. Existing for nearly 500 years (c. 250 B.C.E. to the 220s C.E.), the Parthian state was the only advanced civilization that bordered the Roman Empire. And the two states were not without violent encounters. In 53 B.C.E. the famed Crassus led Roman legions into the Parthian empire only to see his troops massacred and to die violently himself near Carrhae. Later, between 40 and 39 B.C.E., the Parthian king Orodes II conquered and controlled the Roman Near East, including Israel, until Mark Antony organized a counter-offensive that drove his forces from the region. But for the Romans, the damage was done; henceforth, no one would see the Romans as invincible and their control of the Near East certain.
Herod faced this volatile situation and exploited it to his advantage. Indeed it was no coincidence that the Romans entrusted the throne of Judaea to Herod the Great  at the close of 40 B.C.E., the same year of the Parthian conquest. During the campaign the Parthians installed Antigonus, son of Aristobulus II and scion of the Hasmonean dynasty, as king of Judaea. Herod fled to Rome to use this event to make a bid for kingship. He sought out Antony and underscored the Parthian threat (and threw in a bribe for good measure!). As the ancient sources make clear, the strategy worked; the Parthian actions motivated the Senate to make Herod the Great king. In this situation, Herod is best seen as a manipulator of Rome’s confrontation with Parthia for his own advantage.

Herod then took the first opportunity to further his position by working with the Parthians. On the Roman side, Herod was in good shape. After the Senate made him king and Herod pacified his new kingdom, Antony had Antigonus executed in 37 B.C.E. and thus eliminated Herod’s most potent rival. But Herod still had a Parthian problem. He must have feared another Parthian invasion of the Roman Near East.
When the Parthians invaded Palestine in 40 B.C.E., they arrested Hyrcanus II, a high priest and member of the Hasmonean family, and cut off his ears. The Parthians then carried him back to their empire in retreat from Roman troops. Despite the disfigurement, which disqualified him from holding the high priesthood, Hyrcanus remained the ranking member of the royal Hasmonean family. Might the Parthians not try to make Hyrcanus their own vassal king in Judaea? Herod hedged his bets. He wanted to have Hyrcanus in his own possession and to have the Parthians as friends. To achieve these ends, after Orodes perished in 37 B.C.E.—and with him, the worst of the bad blood between Herod and the Parthians—Herod immediately opened diplomatic relations with his successor Phraates IV in 36 B.C.E. He sent the new king presents and pledges and requested permission for the return of Hyrcanus, which was granted. Though not explicitly mentioned in the sources, this exchange must have resulted in some level of official amicability between Herod and the Parthians. In short, it was to the advantage of Herod to be friend of the Romans and the Parthians.

It is ironic, however, that not long after Herod was compelled to break with the Parthian king. In 31/30 B.C.E. Herod’s Roman situation changed dramatically. Defeated at the battle of Actium, Antony took his own life, and Octavian (soon to be hailed “Augustus,” the first Roman emperor) now controlled the Near East . Before embarking for his well-known meeting with Octavian, Herod executed Hyrcanus and thereby eliminated the last surviving Hasmonean heir. This act limited Octavian’s choices and rendered Herod more necessary, even if unsavory, to the Romans. Herod’s judgment in this decision seems sound, at least in its effectiveness—he remained king. The high-profile murder, however, had its downside. It likely alienated Herod from Phraates IV, who would have been irritated by the political black eye Herod’s action created for him. The king’s subjects, especially the Babylonian Jews who honored Hyrcanus, would have been displeased with him, thinking either that Phraates conspired with Herod to bring about the Hasmonean’s death or that the turn of events reflected the king’s weakness of judgment and failure to command respect among regional dynasts. At the very least then Phraates would have had to cut off public diplomatic engagement with Herod. We certainly hear no more of diplomatic exchanges between the two monarchs. But perhaps for Herod there was a thin silver lining. Octavian now could be assured of his loyalty. Where else could Herod turn?
To come to a full appreciation of Herod the Great, we must understand him as more than a one-dimensional Roman front man. He actively and aggressively manipulated the complex imperial circumstances of his day to secure a position of authority for himself. In the process, the “Friend of the Romans” also became a friend of the Parthians, even if the friendship appears short-lived. After more than a century of intense scholarly scrutiny, there remains much more to learn about Herod the Great.1
