The Persian Empire emerged suddenly during the Axial Age. It was unlike the older civilizations that had developed in Egypt, Mesopotamia, India, and China. Indo-Europeans migrated into the highlands of what today is called Iran over the centuries, establishing small kingdoms of Medes, Persians, Elamites, and others. Cyrus, a prince of Persia, was able to establish power over his neighbors around the beginning of the Axial Age. After conquering the wealthy kingdom of Lydia (in what today is called Turkey), he led his forces into Mesopotamia and lay siege to the mighty city Babylon. According to ancient historians, Cyrus had his army divert the water of the Euphrates River into mad-made lakes so they could capture the city of Babylon by marching down the dry riverbed under the walls of the city. The book of Daniel in the Bible confirms that the city fell suddenly to the Persians. They lay claim to the entire Babylonian Empire, although they had to fight numerous battles to consolidate their control over what Babylon had previously claimed.
Cyrus died on the battlefield. His son Cambyses was fighting to retain Egypt when, according to ancient historians, he heard that his younger brother had seized the throne back home. Saying, “That’s impossible—I had my brother killed before I came to Egypt,” Cambyses rushed to return home. In his hurry, he accidently cut his leg with his own sword and eventually died of gangrene. A distant relative named Darius denounced the false younger son of Cyrus and had him killed. (The Persian historians of his time appear reluctant to consider the possibility that the son was genuine and that Darius was lying. Thus, historians have an unsolvable puzzle regarding this event in Persian history.) Taking hold of the kingdom, Darius established its borders and its administrative policies. He attempted to add European Greece to his holdings in 490 BCE; his son Xerxes led a similar invasion ten years later. Greek victories over Persian invaders are vital episodes in Greek history, though the setbacks mattered less to the Persians.
The Persian Empire was divided into satrapies. The ruling satraps were Persian, but the rest of government was locally managed. So far as people paid their taxes and did not violate major Persian laws, the Persian authorities gave them local autonomy. Local languages, religions, customs, and practices were allowed and even encouraged. Earlier empires, including the Assyrians and Babylonians, maintained control of conquered lands by displacing populations (much as the United States did to American tribes and China still does to its citizens today). Persians even allowed people like the Jews to return home, rebuild their cities and temples, and honor their gods. To allow rapid communication through the empire (and rapid movement of the Persian army when needed), the Persian government built highways throughout the lands they controlled. These highways were used by travelers and merchants, beginning a network of trade that would soon link major civilizations of three continents. Government messengers would travel these highways, exchanging horses at each station along the way; this practice, revived in the United States, was known as the Pony Express. Advisors to the government were called Magi. Like the Cabinet of the United States presidency, magi were experts in a variety of areas, including science, history, social studies, religious texts, and law. Their influence as a class of advisors to kings and government officials would remain long after the Persian Empire had fallen to pieces.
The official religion of the Persian Empire was Zoroastrianism. Founded by a man known both as Zoroaster and Zarathustra, this religion has always taught that only one god exists and that all competing gods are liars and demons, not truly gods. Zoroastrianism acknowledges the existence of a secondary evil being who opposes the true god; people in the world must choose between supporting the good or the evil. Support for the good includes piety, unselfishness, care for neighbors, and care of the environment. Support for the evil includes ignorance about god, selfishness, abuse of other people, and destruction of the environment. Those who have supported the good find, at death, that they travel a broad avenue to Paradise; those who have supported the evil find that avenue narrow—in some cases, as narrow as the blade of a knife—and they risk falling off the avenue into unending fire. Because the world currently is balanced between good and evil, each human choice influences the outcome of the world. However, most Zoroastrians are convinced that, in the end, good will overcome evil.
Respect for the environment includes maintaining the purity of the elements—earth, water, air, and fire. Various fire ceremonies are part of Zoroastrian practice. A person who dies cannot be buried (polluting the earth), burned (polluting air and fire), or thrown into the sea (polluting the water). Instead, their bodies are left on platforms to be consumed by birds of the air, nourishing nature and recycling the physical part of human existence while increasing the likelihood of a safe journey to Paradise.
Some historians identify Zarathustra as an Axial Age teacher; others say he lived centuries before the Axial Age. Darius appears to be the first Persian Emperor to endorse Zoroastrianism formally. If Zarathustra was not born until around the time of Cyrus, he may well have been influenced in his beliefs by Israelites relocated into his vicinity by the Assyrian Empire. If he lived much earlier, his ideas may have helped shape Hebrew belief, thus contributing to Jewish, Christian, and Muslim teachings.
“Paradise” is a loan-word from the Hebrew language. So is “Satan”—Satan is the prosecuting attorney in a Persian court of law. (For Christians, Jesus is a defense attorney, an Advocate before the Father.) The images of Paradise for the good and unending fire for the evil have been adopted from Zoroastrianism into Christian and Muslim thought. One branch of Christianity, called Manichaeism, deliberately blended Zoroastrian and Christian beliefs. Manichaeism was rejected by early Christians (including Augustine of Hippo, who in his earlier years had been a Manichee). It was seen as placing too much responsibility for human salvation and for the world’s future condition on human behavior and decisions, rather than trusting the promises of an Almighty God and the victory won by Christ on the cross. Modern Christian preachers who stress the beauty of heaven and the horrors of hell and who call upon their listeners to choose between them reflect Manichaean theology rather than that of the Bible.
