Mesopotamia, for 2,000 years a stronghold of Semitic-speaking peoples, now 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.

By the fourth century B.C., nearly all of Babylon opposed the Achaemenids. Thus, when the Iranian forces stationed in B 123e Babylon surrendered to Alexander the Great of Macedon in 331 B.C. all of Babylonia hailed him as a liberator. Alexander quickly won Babylonian favor when, unlike the Achaemenids, he displayed respect for such Babylonian traditions as the worship of their chief god, Marduk. Alexander also proposed ambitious schemes for Babylon. He planned to establish one of the two seats of his empire there and to make the Euphrates navigable all the way to the Persian Gulf, where he planned to build a great port. Alexander's grandiose plans, however, never came to fruition. Returning from an expedition to the Indus River, he died in Babylon--most probably from malaria contracted there in 323 B.C. at the age of thirty-two. In the politically chaotic period after Alexander's death, his generals fought for and divided up his empire. Many of the battles among the Greek generals were fought on Babylonian soil. In the latter half of the Greek period, Greek military campaigns were focused on conquering Phoenician ports and Babylonia was thus removed from the sphere of action. The city of Babylon lost its preeminence as the center of the civilized world when political and economic activity shifted to the Mediterranean, where it was destined to remain for many centuries.

Although Alexander's major plans for Mesopotamia were unfulfilled, and his generals did little that was positive for Mesopotamia, the effects of the Greek occupation were noteworthy. Alexander and his successors built scores of cities in the Near East that were modeled on the Greek city-states. One of the most important was Seleucia on the Tigris. The Hellenization of the area included the introduction of Western deities, Western art forms, and Western thought. Business revived in Mesopotamia because one of the Greek trade routes ran through the new cities. Mesopotamia exported barley, wheat, dates, wool, and bitumen the city of Seleucia exported spices, gold, precious stones, and ivory. Cultural interchange between Greek and Mesopotamian scholars was responsible for the saving of many Mesopotamian scientific, especially astronomical, texts.

In 126 B.C., the Parthians (or Arsacids), an intelligent, nomadic people who had migrated from the steppes of Turkestan to northeastern Iran, captured the Tigris-Euphrates river valley. Having previously conquered Iran, the Parthians were able to control all trade between the East and the Greco-Roman world. For the most part, they chose to retain existing social institutions and to live in cities that already existed. Mesopotamia was immeasurably enriched by this, the mildest of all foreign occupations of the region. The population of Mesopotamia was enormously enlarged, chiefly by Arabs, Iranians, and Aramaeans. With the exception of the Roman occupation under Trajan (A.D. 98- 117) and Septimius Severus (A.D. 193-211), the Arsacids ruled until a new force of native Iranian rulers, the Sassanids, conquered the region in A.D. 227.

Little information is available on the Sassanid occupation, which lasted until A.D. 636. The north was devastated by battles fought between Romans and Sassanids. For the most part, the Sassanids appear to have neglected Mesopotamia. By the time the enfeebled Sassanid Empire fell to Muslim Arab warriors, Mesopotamia was in ruins, and Sumero-Akkadian civilization was entirely extinguished. Sassanid neglect of the canals and irrigation ditches vital for agriculture had allowed the rivers to flood, and parts of the land had become sterile. Nevertheless, Mesopotamian culture passed on many traditions to the West. The basic principles of mathematics and astronomy, the coronation of kings, and such symbols as the tree of life, the Maltese cross, and the crescent are part of Mesopotamia's legacy.
