It had now been five years, from the summer of 330, since Alexander had left Ecbatana in pursuit of Darius. His presence was urgently needed, for the government of the empire was in chaotic state so far as the central administration was concerned. Fortunately the attempts at an uprising had generally been feeble, and were easily and loyally suppressed by the satraps where they did occur. Only one gave trouble, a revolt in Bactria, initiated first of all by Greek mercenaries and taken up by the native inhabitants as far as the border of Scythia. This lasted some time, and peace was not restored until after Alexander’s death.
But the maladministration of the conquered provinces was more serious than these uprisings. During Alexander’s absence in the Far East there had been boundless liberty in the financial plundering of the people. Peculation was the rule everywhere, and it was common to the Persian official class, to whom the government of the satrapies had been intrusted. Trained as these officers had been in maladministration and corruption, they had no notion of following different standards, simply because there was a different ruler. While Alexander was in Bactria he had been forced to deprive several satraps of their governments. It was time for the strong arm of the king to be felt, and there was no doubt about his intentions and aims. Many Persian satraps were executed and their places taken by Macedonian officers. But while Alexander had been away the infection had spread to European office-holders, both military and civil. We hear, for example, of the death penalty being inflicted on Greek commanders of the troops in Media, who had plundered graves and temples and had signalized their rule over the subject population by systemic oppression.
Among the guiltiest of this class was the minister of finance, Harpalus, who treated the state’s money as his private property, had brought over from Athens a company of gay comrades, and was living the easy, reckless life of an Oriental satrap. His previous record had been anything but clean; before the battle of Issus he had been obliged to return to Greece and had only come back to Asia because he had received the royal pardon. He knew that there was no chance of finding the king amenable to excuses or explanations; so with 5000 talents taken from the treasury, he raised a body of 6000 mercenaries and departed for the sea coast, hoping to stir up a revolt. The scheme was a pitiable failure; no satrap held out a hand to him; and finally Harpalus sailed to Athens, where he had influence and could count on a welcome, because of the strong anti-Macedonian feeling in the city.
Alexander showed his appreciation of the lesson of Harpalus’ official career by ordering the governors of the provinces to dismiss all soldiers they had collected on their own authority. Now that the period of military expansion was closed, the king devoted himself to the organization of the empire, following the lines he had worked out originally, which tended to the amalgamation of the Greek and Persian elements. This ideal survived the experience of maladministration, and Alexander held fast to it, despite the opposition of the officers of his army. He seems to have believed firmly in the possibility of educating politically the Asiatic peoples so that they could be ruled without display of despotic power, and he was just as firm in trusting to the loyalty of the Persian ruling class to carry out this program of interracial conciliation. In doing so he failed to take account of the Persian’s deep-rooted dislike of the Greeks, which with Oriental wiliness his new subjects could conceal, but which was ever present as an inducement to them to take advantage of the first opportunity that offered to throw off the yoke imposed upon them by the conquest.
Alexander planned to make his scheme a success by marrying the daughters of the Persian official class to the Macedonian officers. He led the way by claiming, as the successor of the Great King, the right to have more than one legitimate wife, and after his return from India he added to his royal household a daughter of Darius, Stateira, and a daughter of Ochus, Parysatis. Alexander’s close friend, Hephæstion, received another daughter of Darius, and altogether eighty of the high officers in command of the Macedonian army were married to Persian women of high degree. The wedding festivities were made a national affair, and took place at Susa on the same day with great ceremonial, all the brides receiving from Alexander marriage portions. The Macedonian private soldiers, who followed the example of their chief on this occasion, were richly rewarded.
It is said that the officers were as dissatisfied with the matrimonial schemes of the king as they had been with his plans for further conquest in India; in any case, it is known that on the king’s death there was a general movement among them to get rid of their Persian helpmates. The discontent among the rank and file of Alexander’s followers with his program of social equality between Greek and Persian could not be appeased, even when he paid their debts at the time of the “Union of the Two Races” festival, an act of bounty which cost him about $5,000,000. The hostility to Persian influence was accentuated by the introduction of foreign troops into the army. This was naturally a step required by the necessity of raising a force greater than Greece could possibly supply. That thinly populated country must have been already drained to the point of exhaustion by the demands already made upon it to fill up the losses during the years of constant campaigning. And as a matter of fact, we know that a year and a half after the passage of the Hellespont with 35,000 men, Alexander led to battle at Arbela about 60,000, and in the years during which the expedition was moving in the Far East, the various additional troops must have equaled altogether 50,000 men. The substitution of Persian contingents for Greek soldiers was a matter of plain necessity. They received lower pay, they cost less to feed, without considering the saving made in the high cost of transportation of bodies of men from continental Greece to the interior of Asia.
Orders had therefore been given to draw 30,000 young men from the conquered provinces and to prepare them for military services according to Macedonian methods. A further and more radical stage in the amalgamation policy was reached when Persians were enrolled in the Macedonian phalanx and Asiatic horsemen in the élite regiment of the Hetæroi; even in the life guards distinguished Persians were received, and the command of that force was assigned to a warrior from Bactria, Hystaspes.
These leveling measures were more than the Macedonian veterans could endure, and they became openly mutinous when Alexander proposed to dismiss those who had been longest in the service. The whole army stood together and told the king that they would serve no longer, and that he would see how he could do without them, now that he had his Persians to serve under him. Alexander then set to work to organize purely Persian regiments on the Macedonian model, a Persian life guard, a Persian squadron of Hetæroi, and a Persian phalanx. This satisfied the Macedonians, and they were farther placated by being given precedence over the various Persian units of the army. Under these conditions, the veterans were willing to be dismissed, and they received one talent as a bonus and full pay until they were actually on Macedonian soil. Moreover, the king agreed to provide for the education of their children. Ten thousand men on these terms returned to Greece.
A more effective means for bringing together the two races on an equal footing was the establishment of military colonies throughout the empire. At an early stage of the expedition this had been adopted as the readiest way of keeping peace in the conquered territory. Tyre and Gaza, after the native population had been sold into slavery, received a new population of Greek origin. We have already noted the extension of this scheme in the Far Eastern provinces and in India. Altogether seventy cities are said to have been founded by Alexander. These colonies, though primarily intended for military purposes, became centers of industrial communication and of civilization. The case of the Egyptian Alexandria is so well known that it does not require to be stressed. Less familiar are the proofs of Alexander’s sagacity as a founder of flourishing towns in other parts of his empire. Alexandria, on the Persian Gulf, continued through the whole period of antiquity to be the greatest emporium of the whole region of Mesopotamia. Alexandria in Arcia (Herat) and Alexandria in Arachosia (Candahar) are still to-day important towns in Persia.
Despite his absorption in military interests, Alexander found time for looking after the economic development of his empire. The Indian Ocean was opened to commerce by the remarkable voyage of Nearchus which concluded the Indian expedition. Attempts were made to circumnavigate the Arabian peninsula, and, though they failed, yet a considerable portion of the coast was explored. The Caspian Sea was also the scene of exploring adventures, because it was supposed to be a part of the vast ocean by which the earth was surrounded. The Tigris was freed from obstruction and made navigable; the ancient irrigation canals in Babylonia were restored; and a beginning was made in constructing a harbor near Babylon.
