PARTHIA (Illustrated). George Rawlinson
Lysias, exercised the chief power, and was soon engaged in a war with the Jews, whom the death of Epiphanes had encouraged to fresh efforts. The authority of Lysias was further disputed by a certain Philip, whom Epiphanes, shortly before his death, had made tutor to the young king. The claims of this tutor to the regent’s office being supported by a considerable portion of the army, a civil war arose between him and Lysias, which raged for the greater part of two years (B.C. 163-2), terminating in the defeat and death of Philip. But Syrian affairs did not even then settle down into tranquillity. A prince of the Seleucid house, Demetrius by name, the son of Seleucus IV., and consequently the first cousin of Eupator, was at this time detained in Rome as a hostage, having been sent there during his father’s lifetime as a security for his fidelity. Demetrius, with some reason, regarded his claim to the Syrian throne as better than that of his cousin, the son of the younger brother, and being in the full vigor of early youth, he determined to assert his pretensions in Syria, and to make a bold stroke for the crown. Having failed to obtain the Senate’s consent to his quitting Italy, he took his departure secretly, crossed the Mediterranean in a Carthaginian vessel, and, landing in Asia, succeeded within a few months in establishing himself as Syrian monarch.
From this review it sufficiently appears that the condition of things, both in Syria and Bactria, was favorable to any aspirations which the power that lay between them might entertain after dominion and self-aggrandizement. The Syrian and Bactrian kings, at the time of Mithridates’s accession, were, both of them, men of talent and energy; but the Syrian monarch was soon involved in difficulties at home, while the Bactrian had his attention attracted to prospects of advantage in a remote quarter, Mithridates might, perhaps, have attacked the territory of either with an equal chance of victory; and as his predecessor had set him the example of successful warfare on his western frontier, we might have expected his first efforts to have been in this direction, against the dependencies of Syria. But circumstances which we cannot exactly trace determined his choice differently. While Eucratidas was entangled in his Indian wars, Mithridates invaded the Bactrian territory where it adjoined Parthia, and added to his Empire, after a short struggle, two provinces, called respectively Turiua and that of Aspionus. It is conjectured that these provinces lay towards the north and the north-west, the one being that of the Turanians proper, and the other that of the Aspasiacae, who dwelt between the Jaxartes and the Oxus. But there is scarcely sufficient ground for forming even a conjecture on the subject, since speculation has nothing but the names themselves to rest upon.
Successful in this quarter, Mithridates, a few years later, having waited until the Syrian throne was occupied by the boy Eupator, and the two claimants of the regency, Lysias and Philip, were contending in arms for the supreme power, made suddenly an expedition towards the west, falling upon Media, which, though claimed by the Syrian kings as a province of their Empire, was perhaps at this time almost, if not quite, independent. The Medes offered a vigorous resistance to his attack; and, in the war which followed, each side had in turn the advantage; but eventually the Parthian prince proved victorious, and the great and valuable province of Media Magna was added to the dominons of the Arsacidae. A certain Bacasis was appointed to govern it, whether as satrap or as tributary monarch is not apparent; while the Parthian king, recalled towards home by a revolt, proceeded to crush rebellion before resuming his career of conquest.
The revolt which now occupied for a time the attention of Mithridates was that of Hyrcania. The Hyrcanians were Arians in race; they were brave and high-spirited, and under the Persian monarchs had enjoyed some exceptional privileges which placed them above the great mass of the conquered nations. It was natural that they should dislike the yoke of a Turanian people; and it was wise of them to make their effort to obtain their freedom before Parthia grew into a power against which revolt would be utterly hopeless. Hyrcania might now expect to be joined by the Medes, and even the Mardi, who were Arians like themselves, and could not yet have forgotten the pleasures of independence. But though the effort does not seem to have been ill-timed, it was unsuccessful. No aid was given to the rebels, so far as we hear, by any of their neighbors. Mithridates’s prompt return nipped the insurrection in the bud; Hyrcania at once submitted, and became for centuries the obedient vassal of her powerful neighbor.
The conquest of Media had brought the Parthians into contact with the rich country of Susiana or Elymais; and it was not long before Mithridates, having crushed the Hyrcanian revolt, again advanced westward, and invaded this important province. Elymais appears to have a had a king of its own, who must either have been a vassal of the Seleucidse, or have acquired an independent position by revolt after the death of Epiphanes. In the war which followed between this monarch and Mithridates, the Elymseans proved wholly unsuccessful, and Mithridates rapidly overran the country and added it to his dominions. After this he appears to have received the submission of the Persians on the one hand and the Babylonians on the other, and to have rested on his laurels for some years, having extended the Parthian sway from the Hindoo Koosh to the Euphrates.
The chronological data which have come down to us for this period are too scanty to allow of any exact statement of the number of years occupied by Mithridates in effecting these conquests. All that can be said is that he appears to have commenced them about B.C. 163 and to have concluded them some time before B.C. 140, when he was in his turn attacked by the Syrians. Probably they had been all effected by the year B.C. 150; since there is reason to believe that about that time Mithridates found his power sufficiently established in the west to allow of his once more turning his attention eastward, and renewing his aggressions upon the Bactrian kingdom, which had passed from the rule of Eucratidas under that of his son and successor, Heliocles.
Heliocles, who was allowed by his father a quasi-royal position, obtained the full possession of the Bactrian throne by the crime of parricide. It is conjectured that he regarded with disapproval his father’s tame submission to Parthian ascendency, and desired the recovery of the provinces which Eucratidas had been content to cede for the sake of peace. We are told that he justified his crime on the ground that his father was a public enemy; which is best explained by supposing that he considered him the friend of Bactria’s great enemy, Parthia. If this be the true account of the circumstances under which he became king, his accession would have been a species of challenge to the Parthian monarch, whose ally he had assassinated. Mithridates accordingly marched against him with all speed, and, easily defeating his troops, took possession of the greater part of his dominion. Elated by this success, he is said to have pressed eastward, to have invaded India, and overrun the country as far as the river Hydaspes, but, if it be true that his arms penetrated so far, it is, at any rate, certain that he did not here effect any conquest. Greek monarchs of the Bactrian series continued masters of Oabul and Western India till about B.C. 126; no Parthian coins are found in this region; nor do the best authorities claim for Mithridates any dominion beyond the mountains which enclose on the west the valley of the Indus.
By his war with Heliocles the empire of Mithridates reached its greatest extension. It comprised now, besides Parthia Proper, Bactria, Aria, Drangiana, Arachosia, Margiana, Hyrcania, the country of the Mardi, Media Magna, Susiana, Persia and Babylonia. Very probably its limits were still wider. The power which possessed Parthia, Hyrcania, and Bactria, would rule almost of necessity over the whole tract between the Elburz range and the Oxus, if not even over the region between the Oxus and the Jaxartes; that which held the Caspian mountains and eastern Media could not fail to have influence over the tribes of the Iranic desert; while Assyria Proper would naturally follow the fortunes of Babylonia and Susiana. Still the extent of territory thus indicated rests only on conjecture. If we confine ourselves to what is known by positive evidence, we can only say that the Parthian Kingdom of this period contained, at least, twelve provinces above enumerated. It thus stretched from east to west a distance of fifteen hundred miles between the Suleiman mountains and the Euphrates, varying in width from three or four hundred miles—or even more—towards the west and east, to a narrow strip of less than a hundred miles toward the centre. It probably comprised an area of about 450,000 square miles; which is somewhat less than that of the modern Persia.
Unlike the modern Persia, however, the territory consisted almost entirely of productive regions. The excellent quality of the soil in Parthia Proper, Hyrcania, and Margiana, has been already noticed. Bactria, the next province to Margiana towards the east, was less uniformly fertile; but still it contained a considerable proportion of good land along the course
