In spite of its drawbacks, this system was preferable to that hitherto employed in the East, for it gave the king a regular budget, kept the provinces under his power, and made national revolts very difficult. The death of each king was no longer followed by insurrections which took a great part of the following reign to quell. Darius had not only the glory of organising the Persian empire, but he invented a form of government which served henceforth as a pattern to the great oriental states. His fame as an administrator has even obscured his military renown, for it is often forgotten that he increased his empire while regulating its administration.
Later Conquests of Darius
Darius’ victories left the Persians with only India on the east, and Greece on the west, in which to expand, as their territory in other directions extended to the seas, or to obstacles untraversable by the heavy armies of the period. The empire was bounded on the north by the Black Sea, the Caucasus Mountains, the Caspian Sea, and the steppes of Tartary, and on the south by the Erythræan Sea, the sandy tableland of Arabia, and the desert of Africa.
About the year 512 the Persians seem to have penetrated farther east. From the heights of Iran they commanded the immense plains of the Punjab. Darius invaded and conquered this country, and formed thereof the satrapy of India. Then, instead of fulfilling his intention of going beyond the Ganges, he had the southern regions explored. A fleet constructed at Peukala and placed under the command of a Greek admiral, Scylax a Carian, descended the Indus to its mouth and subjugated the tribes who lived on the banks of the river, and when he reached the sea, he turned to the west and in less than thirty months reached the coasts of Gedrosia and Arabia.
The Persians might have had a brilliant and lucrative career in India. It is not known what prevented them from following up their first success and turned their attention to the West, where Darius planned to conquer the Greeks of Europe. But before setting out on that expedition, prudence warned him to conquer, or at least to frighten, the people who might disturb his course, so he attacked the Scythians.
The first expedition, commanded by Ariaramnes, satrap of Cappadocia, crossed the Pontus Euxinus, landed some thousands of men on the opposite coast, and made some prisoners, who furnished the Persian generals with the information they needed. With this knowledge, Darius crossed the Bosporus with eight hundred thousand men, subjugated the eastern coast of Thrace, and crossed the Danube on a bridge of boats, made by the Greeks of Ionia. The Scythians would not fight, but having destroyed the fodder, and filled up the wells, they drove off their cattle and took refuge in the interior, leaving the enemy to fight against famine, and the impassability of the country.[e]
We cannot pause to dwell upon the details of this campaign. But there is one incident chronicled by Herodotus that must be transcribed because of the interesting light it throws upon the relations of the antagonists.
“The Scythians,” says Herodotus, “discovering that the Persians were in extreme perplexity, hoped that by detaining them longer in their country, they should finally reduce them to the utmost distress: with this view, they occasionally left exposed some of their cattle with their shepherds, and artfully retired; of these, with much exultation, the Persians took possession.
“This was again and again repeated; Darius nevertheless became gradually in want of almost every necessary: the Scythian princes, knowing this, sent to him a messenger, with a bird, a mouse, a frog, and five arrows, as a present. The Persians inquired of the bearer, what these might mean; but the man declared that his orders were only to deliver them and return: he advised them, however, to exert their sagacity, and interpret the mystery.
“The Persians accordingly held a consultation on the subject. Darius was of opinion, that the Scythians intended by this to express submission to him, and give him the earth and the water which he required. The mouse, as he explained it, was produced in the earth, and lived on the same food as man; the frog was a native of the water; the bird bore great resemblance to a horse; and in giving the arrows, they intimated the surrender of their power: this was the interpretation of Darius. Gobryas, however, one of the seven who had dethroned the Magus, thus interpreted the presents: ‘Men of Persia, unless like birds ye shall mount into the air, like mice take refuge in the earth, or like frogs leap into the marshes, these arrows shall prevent the possibility of your return to the place from whence you came.’ This explanation was generally accepted.”
This quaint recital suggests that the Persians were in dire straits; but the result was less disastrous than the Scythians anticipated. Darius managed to provision his army, and for some weeks he traversed the steppes, even penetrating, it has been supposed, to the heart of Russia, burning and sacking all the villages on the road, and then returning south with no reverses.a During his absence, the barbarians begged the Greeks to destroy their bridge of boats and return to their own country. Miltiades of Athens, tyrant of the Thracian Chersonesus, wished to accede to this request, but Histiæus of Miletus opposed the plan, and his advice was followed. So Darius returned safe and sound to Asia, after having left Megabazus with an army of eighty thousand men, with which he subjugated in Thrace one tribe and town after another, and in 506, the king of Macedonia became a vassal to the Persian empire.
The Scythian expedition is generally regarded as the caprice of a despot, but it really was a well-conceived and well-carried out plan. It gave Persia the additional province of Thrace, and also brought about a state of peace which was of great consequence. For the Scythians now held the Persians in such fear that the frontiers were henceforth quite freed from their incursions, and Darius was at liberty to pursue his plans of conquest in the West.
[513-487 B.C.]
As Thrace and Macedonia were conquered, the Persians were now in direct contact with Greece proper. The invasion which had been planned was prevented by a revolt of Asiatic Greece. It is needless to give the details of the rebellion in Ionia. For the first time since the accession of Cyrus, the Persian empire met a serious reverse which threatened its safety. Sardis was burned, Caria, the people of the Hellespont, and Cyprus shook off the yoke of the Great King, and if they had been less disunited the Greeks of Asia might probably have remained free. After their defeat Darius thought of avenging himself on the Athenians and Eretrians for having taken part in the struggle. The first expedition under Mardonius came to grief (492), and two years later Datis and Artaphernes landed in Attica where they were beaten at Marathon.[32] But the old king did not lose heart, and after devoting three years to collecting arms, provisions, soldiers, and ships, he set out on the expedition in 487, when he was stopped by an unexpected event. Egypt broke out in revolt. The Persians were expelled and a native ruler, Khabbash, placed on the Egyptian throne, which he managed to hold for three years.
