Achaemenid Iraq

In 539 B.C., Babylon fell to Cyrus the Great (550-530 B.C.). In addition to incorporating Babylon into the Iranian empire, Cyrus the Great released the Jews who had been held in captivity there. Mesopotamia, for 2,000 years a stronghold of Semitic-speaking peoples, fell to Indo-European rule that persisted for 1,176 years. Cyrus, one of history's truly great leaders, ruled with a firm hand, but he was also well attuned to the needs of his subjects. Upon assuming power, he immediately replaced the savagery of the Assyrians with a respect for the customs and the institutions of his new subjects. He appointed competent provincial governors (the predecessors of the Persian satraps), and he required from his subjects only tribute and obedience. Following Cyrus's death, a brief period of Babylonian unrest ensued that climaxed in 522 B.C. with a general rebellion of Iranian colonies.

Between 520 and 485 B.C., the efficient and innovative Iranian leader, Darius the Great, reimposed political stability in Babylon and ushered in a period of great economic prosperity. His greatest achievements were in road building--which significantly improved communication among the provinces--and in organizing an efficient bureaucracy. Darius's death in 485 B.C. was followed by a period of decay that led to a major Babylonian rebellion in 482 B.C. The Iranians violently quelled the uprising, and the repression that followed severely damaged Babylon's economic infrastructure.

The first Iranian kings to rule Iraq followed Mesopotamian land-management practices conscientiously. Between 485 B.C. and the conquest by Alexander the Great in 331 B.C., however, very little in Babylon was repaired and few of its once-great cities remained intact. Trade also was greatly reduced during this period. The established trade route from Sardis to Susa did not traverse Babylonia, and the Iranian rulers, themselves much closer to the Orient, were able to monopolize trade from India and other eastern points. As a result, Babylonia and Assyria, which together formed the ninth satrapy of the Persian Empire, became economically isolated and impoverished. Their poverty was exacerbated by the extremely high taxes levied on them: they owed the Iranian crown 1,000 talents of silver a year, in addition to having to meet the extortionate demands of the local administrators, and they were responsible for feeding the Iranian court for four months every year.

Iranian rule lasted for more than 200 years, from 551 B.C. to 331 B.C. During this time, large numbers of Iranians were added to Mesopotamia's ethnically diverse population. The flow of Iranians into Iraq, which began during the rein of the Achaemenids, initiated an important demographic trend that would continue intermittently throughout much of Iraqi history. Another important effect of Iranian rule was the disappearance of the Mesopotamian languages and the widespread use of Aramaic, the official language of the empire.
