The Historians' History of the World 08

Arsaces Tiridates soon added Hyrcania to his realm and raised a great host to maintain himself against Seleucus, but still more against a nearer enemy, Diodotus of Bactria. On the death of the latter, the common interests of Parthians and Bactrians as against the Seleucids brought about an alliance between Arsaces Tiridates and Diodotus II. With much ado, Seleucus had got the better of his foreign and intestine foes and kept his kingdom together; and in 238 B.C., or a little later, having made peace with Egypt and silenced his brother, he marched from Babylon into the upper satrapies. Tiridates at first retired and took shelter with the nomadic Apasiacæ, but he advanced again and gained a victory, which the Parthians continued to commemorate as the birthday of their independence. Seleucus was unable to avenge his defeat, being presently called back by the rebellion stirred up by his aunt Stratonice at Antioch. This gave the great Hellenic kingdom in Bactria and the small native state in Parthia time to consolidate themselves. Tiridates used the respite to strengthen his army, to fortify town and castles, and to found the city of Dara or Dareium in the smiling landscape of Abévard. Tiridates, who on his coins appears first merely as Arsaces, then as King Arsaces, and finally as “great king,” reigned thirty-seven years, dying in 211 or 210 B.C. His nation ever held his memory in almost divine honour.

A Parthian King

Seleucus III Soter (226-223 B.C.) died early, and was followed by Antiochus (III) Magnus (223-137 B.C.), who in his brother’s life-time had ruled from Babylon over the upper satrapies. Molon, governor of Media, supported by his brother Alexander in Persis,[29] rose against him in 222 B.C. and assumed the diadem. The great resources of his province, which followed him devotedly, enabled Molon to take the offensive and even to occupy Seleucia, after a decisive battle with the royal general Xenœtas. Babylonia, the Erythræan district, all Susiana except the fortress of Susa, Parapotamia as far as Europus, and Mesopotamia as far as Dura were successively reduced. But the young king soon turned the fortunes of the war. Crossing the Tigris in person, he cut off Molon’s retreat. Molon was forced to accept battle near Apollonia: his left wing passed over to the enemy, and, after a crushing defeat, he and all his kinsmen and chief followers died by their own hands (220 B.C.). Antiochus now marched to Seleucia to regulate the affairs of the East. He used his victory with moderation, mitigating the severities of his minister Hermias; but he had effectually prevented the rise of a new kingdom in the most important province of Iran.

[206-155 B.C.]

In 209 B.C., with one hundred thousand foot and twenty thousand horse, he marched against the new Parthian king, Arsaces II, son and successor of Tiridates. The war ended in a treaty which left Arsaces his kingdom, but beyond question reduced him to a vassal. In 208 B.C. began the much more serious war with Bactria. At length, in 206 B.C., a peace was arranged, and Antiochus was visited in his camp by Demetrius, the youthful son of Euthydemus, who pleased the king so well that he betrothed to him his daughter; Euthydemus was left on his throne, and the two powers swore an alliance offensive and defensive, which cost Bactria no more than certain payments of money, the victualling of the Macedonian troops, and the surrender of the war-elephants. The Bactrian Greeks were grateful for this moderation; their memorial coins place Antiochus Nicator with Euthydemus Theos, Diodotus Soter, and Alexander Philippi among the founders of their political existence.

The kings of Parthia had long remained quiet after the war with Antiochus the Great. Priapatius, successor of Arsaces II (191-176 B.C.), calls himself on his coins “Arsaces Philadelphus,” perhaps because he had married a sister, and was the first of all Parthian kings to call himself “Philhellen.” By the last title he presents himself, at a time when the Seleucid power was sinking, as the protector of his present and future Greek subjects. His eldest son and successor, Phraates I (Arsaces Theopater of the coins), conquered the brave Mardian highlanders and transplanted them to Charax in the neighbourhood of the Caspian Gates, a proof that the Parthians had already detached Comisene and Choarene from Media, probably just after the death of Antiochus the Great.

CONQUESTS OF MITHRIDATES

About 171 B.C. Phraates died and left the crown not to his sons but to his brother Mithridates, a prince of remarkable capacity, who made Parthia the ruling power in Iran. His first conquests, it would seem, were made at the expense of Bactria.
