    While the Phoenicians played a major role in jumpstarting long-distance trade after the collapse of the Bronze Age, they did not create a strong united state. Such a state emerged farther east, however: alone of the major states of the Bronze Age, the Assyrian kingdom in northern Mesopotamia survived. Probably because of their extreme focus on militarism, the Assyrians were able to hold on to their core cities while the states around them collapsed. During the Iron Age, the Assyrians became the most powerful empire the world had ever seen. The Assyrians were the first empire in world history to systematically conquer almost all of their neighbors using a powerful standing army and go on to control the conquered territory for hundreds of years. They represented the pinnacle of military power and bureaucratic organization of all of the civilizations considered thus far. (Note: historians of the ancient world distinguish between the people of the Bronze Age and Iron Age Assyrian kingdoms by referring to the latter as the Neo-Assyrians. The Neo-Assyrians were direct descendants of their Bronze Age predecessors, however, so for the sake of simplicity this chapter will refer to both as the Assyrians.)

    The Assyrians were shaped by their environment. Their region in northern Mesopotamia, Ashur, has no natural borders, and thus they needed a strong military to survive; they were constantly forced to fight other civilized peoples from the west and south, and barbarians from the north. The Assyrians held that their patron god, a god of war also called Ashur, demanded the subservience of other peoples and their respective gods. Thus, their conquests were justified by their religious beliefs as well as a straightforward desire for dominance. Eventually, they dispatched annual military expeditions and organized conscription, fielding large standing armies of native Assyrian soldiers who marched out every year to conquer more territory.

    The period of political breakdown in Mesopotamia following the collapse of the Bronze Age ended in about 880 BCE when the Assyrian king Ashurnasirpal II began a series of wars to conquer Mesopotamia and Canaan. Over the next century, the (Neo-)Assyrians became the mightiest empire yet seen in the Middle East. They combined terror tactics with various technological and organizational innovations. They would deport whole towns or even small cities when they defied the will of the Assyrian kings, resettling conquered peoples as indentured workers far from their homelands. They tortured and mutilated defeated enemies, even skinning them alive, when faced with any threat of resistance or rebellion. The formerly-independent Phoenician city-states within the Assyrian zone of control surrendered, paid tribute, and deferred to Assyrian officials rather than face their wrath in battle.

    The Assyrians were the most effective military force of the ancient world up to that point. They outfitted their large armies with well-made iron weapons; they appear to be the first major kingdom to manufacture iron weapons in large numbers. They invented a messenger service to maintain lines of communication and control, with messengers on horseback and waystations to replace tired horses, so that they could communicate across their empire. All of their conquered territories were obliged to provide annual tributes of wealth (in precious metals and trade goods) which funded the state and the military.

    The Assyrians introduced two innovations in military technology and organization that were of critical importance: a permanent cavalry, the first of any state in the world, and a large standing army of trained infantry. It took until the middle of the eighth century BCE for selective breeding of horses to produce real “war horses” large enough to carry a heavily armed and armored man into and through an entire battle. The Assyrians adopted horse archery from the barbarians they fought from the north, which along with swords and short lances wielded from horseback made chariots permanently obsolete. The major focus of Assyrian taxation and bureaucracy was to keep the army funded and trained, which allowed them to completely dominate their neighbors for well over a century.

    By the time of the reign of Assyrian king Tiglath-Pilezer III (r. 745 – 727 BCE), the Assyrians had pushed their borders to the Mediterranean in the west and to Persia (present-day Iran) in the east. Their conquests culminated in 671 BCE when king Esarhaddon (r. 681 – 668 BCE) invaded Egypt and conquered not only the entire Egyptian kingdom, but northern Nubia as well. This is the first time in history that both of the founding river valleys of ancient civilization, those of the Nile and of Mesopotamia, were under the control of a single political entity.

    The style of Assyrian rule ensured the hatred of conquered peoples. They demanded constant tribute and taxation and funneled luxury goods back to their main cities. They did not try to set up sustainable economies or assimilate conquered peoples into a shared culture, instead skimming off the top of the entire range of conquered lands. Their style of rule is well known because their kings built huge monuments to themselves in which they boasted about the lands they conquered and the tribute they exacted along the way.

    While their subjects experienced Assyrian rule as militarily-enforced tyranny, Assyrian kings were proud of the cultural and intellectual heritage of Mesopotamia and supported learning and scholarship. The one conquered city in their empire that was allowed a significant degree of autonomy was Babylon, out of respect for its role as a center of Mesopotamian culture. Assyrian scribes collected and copied the learning and literature of the entire Middle East. Sometime after 660 BCE, the king Asshurbanipal ordered the collection of all of the texts of all of his kingdom, including the ones from conquered lands, and he went on to create a massive library to house them. Parts of this library survived and provide one of the most important sources of information that scholars have on the beliefs, languages, and literature of the ancient Middle East.

    The Assyrians finally fell in 609 BCE, overthrown by a series of rebellions. Their control of Egypt lasted barely two generations, brought to an end when the puppet pharaoh put in place by the Assyrians rebelled and drove them from Egypt. Shortly thereafter, a Babylonian king, Nabopolassar, led a rebellion that finally succeeded in sacking Nineveh, the Assyrian capital. The Babylonians were allied with clans of horse-riding warriors in Persia called the Medes, and between them the Assyrian state was destroyed completely. Nabopolassar went on to found the “Neo-Babylonian” empire, which became the most important power in Mesopotamia for the next few generations.

    The Neo-Babylonians adopted some of the terror tactics of the Assyrians; they, too, deported conquered enemies as servants and slaves. Where they differed, however, was in their focus on trade. They built new roads and canals and encouraged long-distance trade throughout their lands. They were often at war with Egypt, which also tried to take advantage of the fall of the Assyrians to seize new land, but even when the two powers were at war Egyptian merchants were still welcome throughout the Neo-Babylonian empire.

    A combination of flourishing trade and high taxes led to huge wealth for the king and court, and among other things led to the construction of noteworthy works of monumental architecture to decorate their capital. The Babylonians also inherited the scientific traditions of ancient Mesopotamia, becoming the greatest astronomers and mathematicians yet seen, able to predict eclipses and keep highly detailed calendars. They also created the zodiac used up to the present in astrology, reflecting the age-old practice of both science and “magic” that were united in the minds of Mesopotamians. In the end, however, they were the last of the great ancient Mesopotamian empires that existed independently. Less than 100 years after their successful rebellion against the Assyrians, they were conquered by what became the greatest empire in the ancient world to date: the Persians.
