Darius himself informs us about the rising of the Babylonians and their subjugation. "When I had slain Gaumata, there was a man Atrina, by name, the son of Upadarma, who rebelled in Susiana. He said to the people: 'I am king in Susiana.' Then the inhabitants in Susiana became rebellious; they went over to Atrina; he was king in Susiana. Moreover there was a man of Babylon, Naditabira by name (Nidintabel in the Babylonian text), the son of Aniri; he rebelled in Babylon. He deceived the people thus: 'I am Nabukadrachara (Nabukudurussur), the son of Nabunita.' Then the people of Babylon went over entirely to Naditabira; he seized the throne in Babylon. After this I sent (an army?) to Susiana; Atrina was brought in fetters before me; I slew him. Then I marched to Babylonia against Naditabira, who called himself Nabukadrachara. The army of Naditabira maintained the Tigris, and occupied the river with ships; his whole power protected the Tigris.[228] Auramazda came to my aid; by the grace of Auramazda I crossed the Tigris, and severely defeated the army of Naditabira. On the 26th of the month of Athriyadiya (on the 26th of the month Kislev), then it was, that we gave battle. After this I marched against Babylon. When I went against Babylon, there is a city, by name Zazana on the Euphrates, there this Naditabira, who called himself Nabukadrachara, had come with an army to give me battle. Then we joined battle. Auramazda came to my aid; by the grace of Auramazda I severely defeated the army of Naditabira. The enemy was driven into the water; the water carried him away;[229] on the second day of the month of Anamaka, then we joined battle. Then Naditabira went with a few horse to Babylon, and I went to Babylon. By the grace of Auramazda I took Babylon and captured Naditabira. Then I slew Naditabira at Babylon. While I was in Babylonia these provinces revolted: Persia, Susiana, Media, Assyria, Parthia, Margiana, the Sattagydæ, the Sacæ."[230]

The inscription shows that the inhabitants of Elam gave the signal for revolt, that their leader Atrina attempted to raise once more that ancient kingdom 125 years after its fall. Nabonetus (Nabunahed, Nabunita), the last king of Babylon, had been sent by Cyrus to Carmania and had died there (p. 89). A man, who gave himself out to be his younger son, took the lead of the Babylonians, and once more called into existence the revered name of Nebuchadnezzar. He had time to collect an army, and considered himself strong enough to meet the Persians in the open field. On the eastern border of the ancient kingdom, on the Tigris, he awaited the attack of the Persians; he brings armed ships to the place, that they may facilitate his defence of the right bank, and make it difficult for the enemy to cross the river. The Elamites were overpowered, their leader captured and slain. The heavier task of reducing Babylon was undertaken by Darius himself. The army which he led was obviously the same as that which conquered Susiana; it consisted of Persians and Medes, as is shown by the sequel of the inscription. Darius had to open the campaign against the new Nebuchadnezzar in the same manner in which Cyrus nineteen years previously had begun his war against Nabonetus. He had first to cross the Tigris. This was done, and Nebuchadnezzar retired in a slanting direction across Babylonia to the Euphrates, closely pursued by Darius. On the Euphrates he was again defeated, and his people were driven in part into the river, but he was not cut off from the city as Nabonetus had been by Cyrus; he was able to reach the protection of the walls of Babylon. We know their powers of resistance. The Persians had crossed the Tigris at a place where it is not more than 100 miles distant from the Euphrates, i. e. not far below the Median walls; for the battle on the Tigris was fought on the 26th (or 27th) of Athriadiya, and six days after, on the 2nd of Anamaka, the Babylonian army suffered its second defeat on the bank of the Euphrates at Zazana. As Athriadiya coincides with the Kislev (November-December) and Anamaka with the Tebet (December-January) of the Babylonians (p. 195), the rebellion of Babylonia must have taken place in the summer and the investment of the city in the last weeks of the year 521 B.C. The inscriptions tell us nothing of the length of the siege. On the other hand we have five tablets from the reign of the rebel, Nebuchadnezzar III., all dated from Babylon, and bearing the name of the same witness. They date, in the time of this king, from Kislev 20, to the next Tisri and Marchesvan, i. e. from November-December of the year of the battles down to October-November of the next year.[231] The inscription of Behistun allows that all the central lands of the kingdom, not excepting Persia, rebelled against Darius during the siege. It follows therefore that success at Babylon was long enough delayed to awake the hope that Darius would be checked before Babylonia, and defeated there. The twenty months of Herodotus would carry us from the end of the year 521 B.C. to the autumn of the year 519 B.C.

The rebellion made head everywhere. In spite of the day of Çikathauvatis, the kingdom was going to ruin. The position of Darius was desperate. The longer the siege, the more fixed the belief that he could not succeed, the greater was the progress of the revolt. If he raised the siege to turn against the rebels, that was a proof that he could not conquer Babylon; the confidence of the rebels in their fortunes would be increased, and the army discouraged with which he had conquered on the Tigris and the Euphrates, with which he stood in personal relations, and which he had drawn into close connection with himself. On this army the kingdom rested; it remained yet loyal in the camp at Babylon. The deed in Nisaea had been best confirmed by the fact that Media recognized Darius as king, that he had been able to summon the Median contingent to the field, and by his successes to connect the Median army with himself. "The Persian and Median army which was with me remained faithful; the Median nations which remained at home, revolted"—so we learn from the inscription.[232] Darius perceived that he must not weaken the only support which he had in this difficult crisis, or remove it by his own act. He judged the situation correctly, and remained before Babylon in spite of bad news which was brought to him from all sides. But the resistance was not less stubborn than the attack. It seemed as though the new reign of Darius must come to an end before Babylon. Could it continue beside the defection of the Medes, Parthians, Hyrcanians, Margiani, Sagartians and Sattagydæ, the Armenians, Assyrians, and Susiani, the rebellion of the Persians themselves? Was it possible to check the outbreak of the storm of ruin in the face of the indomitable resistance of Babylon? Only in the distant east and west were there glimpses of light. The satraps of Arachosia and Bactria, Vivana and Dadarshis, remained loyal to Darius and kept their lands in obedience. Asia Minor was quiet; if Darius had not succeeded in removing Oroetes at the right moment, these regions also would have taken up arms against Darius either under him or under some native ruler.

The account of Darius allows us to see that the recently-subdued Susiani were the first to rebel when Darius was delayed at Babylon. After them the Medes rebelled, in order to renew the struggle for the sovereignty between Persia and Media; this was followed in the east by the rebellion of the Sattagydæ, the Parthians, the Hyrcanians, the Margiani, the Sacæ; in the west the Armenians and Syrians took up arms. Finally, even the Persians held out a hand to the subject nations for the overthrow of the kingdom and their own dominion. Vahyazdata, a Persian of the tribe of the Utians (V. 323), declared himself to be the legitimate ruler; the brother of Cambyses was alive; he was no other than Bardiya, the son of Cyrus. The Persians believe him; this second pretender finds many adherents.

The inscription is as follows: "There was a man, by name Martiya; he dwelt in the city of Kuganaka in Persia; he revolted in Susiana; and said to the people: 'I am Ymani, king in Susiana.' There was a man, Fravartis (Phraortes) by name, a Mede. He revolted in Media, and said: 'I am Khsathrita of the family of Uvakhshathra' (Cyaxares). The Median nation then became rebellious towards me; they went over to Fravartis; and he was king in Media. Thereupon I sent an army. I made Vidarna, a Persian, my servant, the general, and said to them: 'Go down and smite the Median army which does not call itself mine.' Then Vidarna marched out. When he came to Media, he fought a battle with the Medes at Marus, a city in Media. By the grace of Auramazda the army of Vidarna conquered that rebellious army on the (twenty-seventh) day of the month Anamaka (of the month Tebet).[233] There was a district Campada (Cambadene) in Media; there my army awaited me. The Parthians and Hyrcanians became rebellious to me, and joined Fravartis. Vistaçpa, my father, was in Parthia; the people left him and revolted. Then Vistaçpa took those who adhered to him and marched against the rebels. On the 22nd day of the month Viyakhna Vistaçpa, by the grace of Auramazda, defeated the rebels near the city of Viçpauvatis in Parthia. I sent my servant, Dadarshis by name, an Armenian, to Armenia. When he came to Armenia, the rebels gathered together and marched against Dadarshis to give battle. By the grace of Auramazda my army defeated the revolted army near Zuza in Armenia, on the 6th day of the month of Thuravahara. The rebels marched against Dadarshis a second time. Near the fortress of Tigra in Armenia on the 18th of Thuravahara my army defeated the rebellious army; they slew 526 of them, and took 520 prisoners.[234] A third time the rebels marched against Dadarshis. Near the fortress of Uhyama in Armenia my army defeated the rebellious army on the 9th day of the month Thaigarshis. There Dadarshis waited till I came to Media. A man, by name Chitratakhma, revolted from me. 'I am king of Sagartia,' he said to the people, 'of the race of Uvakhshathra' (Cyaxares). There is a province Margiana (Margu) by name which revolted from me. They made a man of Margiana, Frada by name, their leader. Against him I sent Dadarshis (Dadarsu) a Persian, my servant, the satrap of Bactria. There was a man, Vahyazdata by name, in the city of Tarava, in the district of Yutiya in Persia; he said to the people: 'I am Bardiya, the son of Kurus.' The Persian nation revolted from me. He was king in Persia. This Vahyazdata, who called himself Bardiya, sent an army to Arachosia against the Persian Vivana, my servant, the satrap of Arachosia."

The rebellion of Phraortes (which took place in the summer of 520 B.C.) was the more dangerous because it was undertaken with the obvious intention of restoring the independence of Media under a scion of the old native royal house, and the name of Cyaxares could not but excite and give new life to national memories among the Medes. Whatever troops Darius could spare, and for this purpose he could only use Persians, he sent under the command of the tribal prince Hydarnes, his associate in the assassination of the Magi, against the Medes, at the same time despatching Dadarshis an Armenian to Armenia, to check the advance of the rebellion there, and mainly, no doubt, to prevent the alliance of the Armenians and the Medes. A whole year after Darius had begun the investment of Babylon, on the 27th day of Anamaka (December-January, 520 B.C.), Hydarnes encountered Phraortes at Marus. He did not obtain any great success. He had to content himself with maintaining against Phraortes the district of Cambadene in the south of Media. In the west of Media, Dadarshis had no better success against his Armenian compatriots. When he had fought two battles, of no great importance, if we are to judge from the losses of the rebels in one, in one month (on the eight and eighteenth), and a third in May (Thaigarshis) of the year 519 B.C., he was compelled to retire to a fortress named Uhyama. In Parthia, to the east of Media, Hystaspes the father of Darius, who was expected to keep these regions of the kingdom in obedience, was not in a position, with the forces at his disposal, to prevent the defection of the Parthians, Hyrcanians, Margiani, and Sacæ. He contented himself with the attempt to prevent the combination of the Parthians and Hyrcanians with Phraortes, and to limit as far as possible the spread of the rebellion. He only succeeded in retaining a part of the Parthians in obedience. The battle at Viçpauvatis (in Viyakhna, i. e. in March, 519), made it possible for him to maintain himself in Parthia, but was far from giving him the control of the land. The troops and generals sent by Darius were not able to prevail against the rebels; in Media and Armenia they were reduced to the defensive, and the same was the case with Hystaspes the father of Darius in Bactria. This collapse of the kingdom and general rebellion was used by a Persian of the tribe of the Utians (Yutiya[235]) in order to win over the Persians once more with the name of Bardiya, and to wrest them from the rule of Darius. Vahyazdata must have found a considerable following in Persia, and his successes must have been important, since he could attempt to extend his dominion to the east over Carmania and Arachosia, and to send an army to Arachosia in order to win this province also from Darius.

The position of Darius before Babylon was hopeless. The danger increased every day, and there was still no prospect of winning the city. We may certainly believe the narrative of Herodotus that Darius left no means untried to reduce it, that he repeated the device of drawing off the water of the Euphrates into the basin of Sepharvaim, by which Cyrus had attained his object twenty years previously; the Babylonians had been taught by that siege to be on their guard in this direction. The account of Darius does not tell us how the city was finally taken; he does not mention the name of Zopyrus. The pressure of the surrounding dangers was so great, the hope of taking the city by force so small, that the son of a tribal king might feel himself called upon to sacrifice himself for the king and the kingdom, to adopt desperate measures. That Zopyrus did take a prominent part in the capture of Babylon is clear from the fact, which we do not learn from Herodotus only, that the satrapy of Babylon was given to him, and remained in his hands during the whole reign of Darius and afterwards. He is said to have lost his life in a rebellion of the Babylonians in the reign of Xerxes.[236] We cannot doubt that after the capture Darius proceeded with greater severity against Babylon than Cyrus had done, that the gates were broken and large spaces of the walls thrown down (p. 234). The inscription of Behistun merely mentions the execution of the third Nebuchadnezzar.

After a siege of twenty months Babylon fell in the autumn of the year 519 B.C. Darius tells us further: "Thereupon I went up from Babylon, and marched to Media. The Susiani were overcome with fear, they seized upon Martiya (p. 242), who was their general, and put him to death. When I had reached Media, there is a city, Kudurus (Kunduru) by name, in Media, to which Fravartis marched against me with an army. Then they gave me battle. Auramazda came to my aid. By the grace of Auramazda I severely defeated the army of Fravartis on the 26th day of the month of Adukanis. Then Fravartis with a few horsemen withdrew to the district of Raga in Media. Then I sent an army against them; Fravartis was captured and brought to me. I cut off his nose, ears, and tongue. He was kept in chains at my gate; all the people saw him. Then I crucified him at Hangmatana (Ecbatana), and the men who were his principal adherents I imprisoned in the citadel of Hangmatana. Then I sent a Persian army from Raga to Vistaçpa, and when it had reached him, he marched out with it. There is a city Patigrabana[237] in Parthia, there Vistaçpa severely defeated that rebellious army on the 1st day of the month of Garmapada; he slew 6560 of them, and took 4182 captives. Then the land of Parthia was mine. I sent Vaumiça a Persian, my servant, to Armenia; when he came there the rebels collected to give battle to Vaumiça. At Achitu in Assyria my army defeated the rebels on the 15th day of Anamaka, and slew 2024 of them. A second time they gathered together and marched against Vaumiça. There is a district Antiyara (Otiara) by name, in Armenia; there they fought on the last day of the month of Thuravahara (Yiyar 30). By the grace of Auramazda my army defeated the rebels severely; they slew 2045 and took 1559 prisoners. Against Chitratakhma (the leader of the rising of the Sagartians), I sent a part of the Persian and Median army.[238] I made Takhmaçpada, a Mede, the general. Takhmaçpada fought with Chitratakhma and my army defeated the rebellious army, seized Chitratakhma, and brought him to me. I cut off his nose and ears, he lay in chains at my gate; all the people saw him. Then I crucified him at Arbira (Arbela in Assyria). Dadarshis, a Persian, my servant, the satrap of Bactria, fought a battle with the Margiani (Frada was the leader of the rising here) on the 23rd day of the month of Atriyadiya. By the grace of Auramazda my army defeated the hostile army very severely. Dadarshis slew 4203 of them, and took 6562 prisoners.[239] Then the land was mine. Vahyazdata, who called himself Bardiya, sent an army to Arachosia against the Persian Vivana, my servant, the satrap of Arachosia. 'Go up,' he said to them; 'defeat Vivana and the army, which calls itself the army of king Darius.' There is a fortress, Kapisakani by name; there they fought the battle. By the grace of Auramazda my army defeated the rebellious army on the 13th of Anamaka. For a second time the rebels marched against Vivana. In the district of Gandutava (Ganduvada) on the 7th of the month Viyakhna, my army defeated the rebellious army. Then the general of Vahyazdata withdrew with his faithful warriors to a fortress, Arsada by name, in Arachosia. Vivana followed him with an army. Then he seized him and slew him and the captains who were with him. I sent out a part of the Persian and Median army which was with me; I made Artavardiya, a Persian, my servant, the general of it; Artavardiya marched to Persia; the rest of the army went with me to Media. When Artavardiya was in Persia, there is a city Rakha (Racha); to this Vahyazdata who called himself Bardiya marched to fight against Artavardiya. Auramazda came to my aid; on the 12th of Thuravahara my army defeated the army of Vahyazdata very severely. Then Vahyazdata went to Pisicauvada. From thence he marched against Artavardiya and gave him battle. There is a mountain Paraga (Parga) by name; there they fought on the 6th day of Garmapada. By the grace of Auramazda my army defeated that of Vahyazdata; and they seized Vahyazdata and also his chief adherents. Uvadaidaya is a city in Persia; there I crucified Vahyazdata and the captains who were with him."

The connection between these various battles is no doubt as follows. When Babylon had fallen in the autumn of the year 519 B.C. and the new Nebuchadnezzar had been executed, Darius set out in the spring of the year 518 B.C. Hydarnes maintained himself against Phraortes on the western border of Media, Dadarshis against the rebels in Armenia, and Hystaspes in Parthia. The new pretender to the name of Smerdis ruled in Persia, and his attempt to gain possession of the lands farther to the east and of Arachosia was first checked by the defeat which he suffered from the satrap of Arachosia in a battle fought in December of the year 519 B.C. In all these directions, in Armenia and Parthia, help was needed, and the decision lay in Persia and Media. Darius did not direct his march against Persia, but against Media. There, as he acutely saw, lay the main strength of the rebellion. His approach terrified the Susiani; they slay their chief, their king Martiya, and submit. Arrived at the border of Media and Persia, Darius divides his army. To make use of the mutual jealousy of the Persians and Medes, and to prevent any contact of his Median troops with their rebellious kinsmen, he sends the Persian Artavardiya with the Median troops to Persia against Vahyazdata, and with the Persians he marches against Phraortes to Media. Hydarnes waited for him at Campada; the first object was to unite the troops. The road from Susiana to Ecbatana ran through the district of Cambadene. When united with Hydarnes Darius overcomes Phraortes in the month of Adukanis (perhaps in June) of the year 518 at Kudurus, pursues him to Ragha, and takes him prisoner. Before he executed him in front of the citadel of Deioces, Phraortes, and Cyaxares, he had cut off his nose, ears, and tongue, and in this condition he had publicly exhibited him in chains, in order to convince the Medes that they had nothing to hope from the supposed scion of Cyaxares. The rebellion of the Medes is at an end. Darius can divide his forces. From Ragha he sends aid to his father Hystaspes in Parthia, and with this additional aid Hystaspes is able to defeat the rebellion of the Parthians in Garmapada, i. e. in the summer of 518 B.C. At the same time Dadarshis had received the support in Armenia for which he was waiting, under the protection of the fortress of Uhyama. The Persian Vaumiça, who brought up the reinforcements for Darius, defeats the Armenian rebels in Anamaka, i. e. in December of the year 518 B.C.; a second victory of Vaumiça, in Yiyar (May) of the following year (517 B.C.), puts an end to the rebellion in Armenia. A third army was sent by Darius after the fall of Phraortes against the Sagartians; which overpowered them and took their chief Chitratakhma prisoner. Meanwhile Artavardiya, whom Darius had sent from Susiana, when on his march against Phraortes, to check the rebellion in the native land, had fought with success against Vahyazdata. The latter had weakened his forces by sending a detachment to Arachosia. Vivana, the satrap of Arachosia, had repulsed their attack in December 519 at Kapisakani, and in March (Viyakhna) of the year 518 B.C. he had entirely destroyed them. This failure in the east was followed in the same spring by the attack of Artavardiya from the west. First defeated in Thuravahara (April) at Racha, Vahyazdata succumbed in the summer (in Garmapada) at Mount Paraga, five days after Hystaspes had again become master of the Parthians in the north-east of Iran. The forces of the satrap of Bactria, the second Dadarshis, had sufficed to put an end to the rebellion of the Margians.

That which the deed of Çikathauvatis, the assassination of Gaumata in the spring of the year 521 B.C., was intended to prevent, had nevertheless happened. The whole kingdom was disorganised. In ceaseless conflicts, which extended over four years, from the autumn of 521 B.C. to the spring of 517 B.C., Darius had reconquered it, step by step. He had been compelled to reduce by force of arms even the very foundation of it, the native land of Persia, and to carry on once more the conflict between Persia and Media. It had been necessary to repeat the achievements of Cyrus, if not to their full extent yet in part under far more difficult conditions. The new king had passed with success through the severest crisis, and had reorganised the kingdom. This was the result of his indomitable persistence before Babylon. By this means he had retained the Medes and Persians of his army in their fidelity, and by the final success had filled them with self-confidence. The fear which afterwards preceded his arms, certainly rendered more easy the decisive victory of Kudurus and at Mount Paraga.
