The earliest known record of the Persians comes from an Assyrian inscription from c. 844 BC that calls them the ”Parsu” (Parsuash, Parsumash) and mentions them in the region of Lake Urmia alongside another group, the ”Madai” (Medes). For the next two centuries, the Persians and Medes were at times tributary to the Assyrians. The region of Parsuash was annexed by Sargon of Assyria around 719 BC. Eventually the Medes came to rule an independent Median Empire, and the Persians were subject to them.
(”Hakhamanish”), chieftain of the Persians around The Achaemenids were the first to create a centralized state in Persia, founded by Achaemenes700 BC.
Around 653 BC, the Medes came under the domination of the Scythians, and Teispes, the son of Achaemenes, seems to have led the nomadic Persians to settle in southern Iran around this time — eventually establishing the first organized Persian state in the important region of Anshan as the Elamite kingdom was permanently destroyed by the Assyrian ruler Ashurbanipal (640 BC). The kingdom of Anshan and its successors continued to use Elamite as an official language for quite some time after this, although the new dynasts spoke Persian, an Indo-Iranian tongue.
defeated the forces of Astyages, who was then captured by his own nobles and turned over to the triumphant Cyrus, now Teispes’ descendants may have branched off into two lines, one line ruling in Anshan, while the other ruled the rest of Persia. Cyrus II the Great united the separate kingdoms around 559 BC. At this time, the Persians were still tributary to the Median Empire ruled by Astyages. Cyrus rallied the Persians together, and in 550 BCShah of a unified Persian kingdom. As Persia assumed control over the rest of Media and their large empire, Cyrus led the united Medes and Persians to still more conquest. He took Lydia in Asia Minor, and carried his arms eastward into central Asia. Finally in 539 BC, Cyrus marched triumphantly into the ancient city of Babylon. After this victory, he set the standards of a benevolent conqueror by issuing the Cyrus Cylinder, the first charter of human rights. Cyrus was killed in 530 BC during a battle against the Massagetae or Sakas.
Cyrus’ son, Cambyses II, annexed Egypt to the Achaemenid Empire. The empire then reached its greatest extent under Darius I. He led conquering armies into the Indus River valley and into Thrace in Europe. A punitive raid against Greece was halted at the Battle of Marathon. His son Xerxes I tried to subdue the Greeks, but his army was defeated at the Battle of Plataea 479 BC.
The Achaemenid Empire was the largest and most powerful empire the world had yet seen. More importantly, it was well managed and organized. Darius divided his realm into about twenty satrapies (provinces) supervised by satraps, or governors, many of whom had personal ties to the Shah. He instituted a systematic tribute to tax each province. He took the advanced postal system of the Assyrians and expanded it. Also taken from the Assyrians was the usage of secret agents of the king, known as the King’s Eyes and Ears, keeping him informed.
Darius improved the famous Royal Road and other ancient trade routes, thereby connecting far reaches of the empire. He may have moved the administration center from Fars itself to Susa, near Babylon and closer to the center of the realm. The Persians allowed local cultures to survive, following the precedent set by Cyrus the Great. This was not only good for the empire’s subjects, but ultimately benefited the Achaemenids, since the conquered peoples felt no need to revolt.
It may have been during the Achaemenid period that Zoroastrianism reached South-Western Iran, where it came to be accepted by the rulers and through them became a defining element of Persian culture. The religion was not only accompanied by a formalization of the concepts and divinities of the traditional (Indo-)Iranian pantheon but also introduced several novel ideas, including that of free will, which is arguably Zoroaster’s greatest contribution to religious philosophy. Under the patronage of the Achaemenid kings, and later as the ”de-facto” religion of the state, Zoroastrianism would reach all corners of the empire. In turn, Zoroastrianism would be subject to the first sycretic influences, in particular from the Semitic lands to the west, from which the divinities of the religion would gain astral and planetary aspects and from where the temple cult originates. It was also during the Achaemenid era that the sacerdotal Magi would exert their influence on the religion, introducing many of the practices that are today identified as typically Zoroastrian, but also introducing doctrinal modifications that are today considered to be revocations of the original teachings of the prophet.
The Achaemenid Empire united people and kingdoms from every major civilization in south west Asia. For the first time in history, people from very different cultures were in contact with one another under one ruler.
