The First Assyrian Empire.—We have to pass over an interval of two centuries before we find another Assyrian monarch who emulated the distant campaigns of Tiglath-pileser. Assur-natsir-pal (b.c. 883-858) was the first of a line of conquerors who may be regarded as the founders of the first Assyrian empire. From henceforth, too, Assyrian chronology is accurately fixed. The Assyrians counted time by means of certain officers called limmi, who were changed from year to year. The name of a particular limmu consequently indicated the year during which he had held office. Lists of the limmi have been preserved which begin with the reign of Assur-natsir-pal's father and carry us down to that of Assur-bani-pal. As the annals not only of Tiglath-pileser I, but also of an older king, the father of Shalmaneser I, are dated in the years of office of certain limmi it is clear that the institution went back to an early period, and that lists of the older limmi may yet be recovered, carrying us, it may be, to the very foundation of the Assyrian kingdom.
Calah, instead of Assur, had become the royal residence, and from Calah accordingly the Assyrian armies marched forth year after year to conquer and spoil. The fastnesses of the Kurdish mountains were explored, and the Kurdish tribes compelled to pay tribute to the Assyrian king. The cities of Armenia south of Lake Van were ravaged in repeated campaigns, one effect of which seems to have been the introduction of Assyrian culture and writing, and the rise of the Vannic monarchy. The merchant princes of Carchemish bought off the Assyrian attack with rich gifts, but the states on either bank of the Euphrates were overrun, and Assur-natsir-pal made his way across Amanus to the Gulf of Antioch, and across Lebanon to the Mediterranean. Here he received the tribute of the Phoenician cities, among them being Tyre and Sidon. In imitation of Tiglath-pileser I he hunted in northern Mesopotamia, but the elephant had disappeared from the region, and he had to content himself with the wild bull.
Assur-natsir-pal was succeeded by his son Shalmaneser II, whose reign ended in b.c. 823. His long reign was a series of military campaigns. Countries previously untrodden by Assyrian feet were subdued or ravaged with fire and sword. Assyrian armies made their way through the passes of Kurdistan as far as Lake Urumiyeh and the land of the Minni. The newly-founded kingdom of Ararat was shaken, the Tibareni (called Tubal in Scripture) paid tribute, and Tarsus in Cilicia was compelled to open its gates. The passage of the Euphrates was secured by the capture of the Hittite fortress of Pethor at the junction of the Euphrates and the Sajur, and the whole weight of the Assyrian power was hurled against Syria. The Phoenician cities made their peace with the invader by offering gifts; so too did Jehu (Yahua) of Samaria, whose ambassadors are represented on the Black Obelisk. Hamath and Damascus, more especially the latter, had to bear the brunt of the Assyrian attack. In b.c. 853, thirteen years before the embassy of Jehu, Israel and Assyria had already met in the battle-field. A league had been formed by Hamath, Arvad, Ammon, and other states under the leadership of Hadadezer of Damascus—the Ben-hadad of the Old Testament—to resist the Assyrians, and one of the most important of the allies was 'Ahab of Israel,' who brought into the field 2,000 chariots and 10,000 men. But the confederacy was shattered at the battle of Qarqar, though Shalmaneser's own losses were too serious to allow him to follow up the attack. In b.c. 847 Hadadezer and his allies were again defeated, but without any result on the Assyrian side. Seven years later Hazael appears in the place of Hadadezer. Shalmaneser drove him from his camp into Damascus, where he 'shut him up,' taking from him 1,121 chariots and devastating the country as far as the Hauran. It was on this occasion that Jehu offered homage to the conqueror. Shalmaneser had already overrun Babylonia and sacrificed to the gods in Babylon, Borsippa, and Cutha. The Babylonian king was put to death, and the Assyrian troops penetrated into the salt-marshes of the Kaldâ in the extreme south. For a time, therefore, the larger part of western Asia lay at the feet of 'the great king.'
A time came, however, when Shalmaneser could no longer lead his armies in person, but had to entrust them to the Tartan or commander-in-chief. His own son Assur-dain-pal rebelled against him, and led the chief cities of his kingdom, including Nineveh and Assur, into revolt (b.c. 827). The revolt lasted for more than six years, and during its continuance the old king was succeeded by his son Samsi-Rimmon who eventually suppressed the insurrection. Assur-dain-pal seems to have been the original Sardanapallos of the Greeks. The campaigns of Samsi-Rimmon were principally directed against the Kurds and Medes, but towards the end of his reign he invaded Babylonia and defeated its king, Merodach-balásu-iqbi, the Greek Belesys. His successor Rimmon-nirari III (b.c. 810-781) claims to have overcome Media and Kurdistan, Tyre, Sidon, Samaria, and Palastu, 'the land of the Philistines,' under which title the Jews would be included. But his chief exploit was the conquest of Damascus, whose king Marih opened its gates to him and became an Assyrian vassal.
The older Assyrian dynasty, however, was fast coming to an end. In b.c. 753 its last representative, Assur-nirari, mounted the throne. Insurrection had already broken out at the beginning of his predecessor's reign, and pestilence had been added to insurrection. The old capital Assur had led the revolt, a solar eclipse on June 15, b.c. 763 coinciding with its outbreak. The northern provinces had followed the lead of Assur, and though the revolt was crushed for a while, the flame of discontent still smouldered beneath the surface. The greater part of Assur-nirari's short reign was passed in inaction, but in b.c. 746 Calah rebelled, and on the 13th of Iyyar in the following year Pulu or Pul, who took the name of Tiglath-pileser III, after that of the great conqueror of the older dynasty, was proclaimed king. With him begins the history of the second Assyrian empire.
The Second Assyrian Empire.—With the second Assyrian empire a new political idea entered the world. Most of the campaigns made by the earlier Assyrian kings were mere raids, the object of which was booty and captives. It is true that in some cases cities and districts were annexed to the Assyrian kingdom and Assyrian colonists were planted in distant localities. But this was the exception, not the rule. The conquests made in one year by the Assyrian armies had to be made over again in the next. The campaigns of Tiglath-pileser III and his successors had a different object in view. They aimed at bringing the whole civilized world under the rule of 'the great king.' A great political organization was to be built up, which should bring the wealth of Western Asia into the imperial treasury of Nineveh and divert the trade of Phoenicia and Babylon into Assyrian hands. Trade interests had much to do with the wars of the New Empire.
Accordingly, while the frontiers of the kingdom were secured from the wild tribes on the east and north, expedition after expedition was sent westward and southward which pushed steadily forward the Assyrian domination. Satraps and colonists followed in the wake of the generals; and the amount of annual tribute to be paid by each province was defined and rigorously exacted from its governor. The latter was appointed by the king, and held his office at the royal pleasure. At his side were military officers, and under him a body of officials who were responsible to the governor as he was to the king.
The New Empire was thus governed by a vast bureaucracy, at the head of which stood the king. But the bureaucracy was military as well as civil, and the military and civil elements formed a check one upon the other. The military element was, however, predominant, the result of the fact that the empire itself was based on conquest.
The army was carefully trained, well disciplined, and well armed. It thus soon became an irresistible weapon in the hands of a competent master. Before Tiglath-pileser's reign was half over there was no force in western Asia which was capable of resisting it in open fight.
Tiglath-pileser reigned eighteen years (b.c. 745-727), and his organizing abilities proved to be as great as his military skill. An invasion of Babylonia first tested the strength of his army, and resulted in the subjection of the Aramaean tribes in that country to Assyrian rule. Then followed an expedition into Kurdistan. The Medes were massacred, and the Assyrian army pushed its way far eastward to Bikni, 'the mountain of the rising sun.' Next Tiglath-pileser turned to the north-west. Here he was met by a powerful confederacy, at the head of which was the king of Ararat. But the forces of the northern nations were cut to pieces in Komagene, and Arpad, which had become the centre of a hostile Syrian league, was captured after a siege of three years. The league had included Hamath and Azariah of Judah, and Hamath was consequently annexed to the Assyrian empire. The princes of the West hastened to offer homage to the conqueror, among them being Rezon of Damascus and Menahem of Samaria (b.c. 738). Tiglath-pileser was now free to march against Ararat, which had extended its power at the expense of Assyria in the later days of the old dynasty. The country was ravaged up to the gates of its capital, and the Vannic kingdom received a blow from which it never recovered. The Assyrian army next turned eastward to the southern shores of the Caspian, and made its way through Medic and other districts which neither before nor since were trodden by Assyrian feet. The exploit struck terror into the Kurdish tribes, and secured the Assyrian lowlands from their attack.
