4.3.1 The Rise of Persia

The origins of the Persians are murky and stretch back to the arrival of nomadic Indo-European speakers in the Near East, possibly as early as 2000 BCE. Those who reached Persia (modern Iran) are often described as Indo-Iranians or Indo-Aryans. They were generally pastoralists, relying on animal husbandry, living a mostly migratory life, and using the horse-drawn chariot. The extent to which they displaced or blended with existing groups in the region is not clear. From written records of the rise of the Neo-Assyrian Empire during the ninth century BCE, we know the Assyrians conducted military campaigns against and exacted tribute from an Indo-Iranian group called the Persians. The Persians lived in the southern reaches of the Zagros Mountains and along the Persian Gulf, in general proximity to the Medes with whom they shared many cultural traits.

Much of what we know about the early Persians comes from the work of the ancient Greek historian Herodotus, who was born about 484 BCE (Figure 4.28). According to Herodotus, Persia was made a vassal of Media in the seventh century BCE but freed itself in the sixth century BCE under the leadership of Cyrus II, also called Cyrus the Great. Inscriptions from the period suggest that Cyrus was likely a member of the Persian royal family, the Achaemenid dynasty. Once in power, he reorganized the Persian state and its military to mirror those of the Median Empire. This step included creating divisions for cavalry, archers, and infantry and setting up special training for the cavalry. Then, in 550 BCE, just a few years into his reign, Cyrus sent his military to challenge the Medes, whereupon the Median troops revolted, handed over their king, and accepted Cyrus’s rule. He then proceeded to integrate the Median elite and officials into his own government. The Median domains had become the Persian Empire.

Between 550 and 539 BCE, Cyrus sent his armies east and west to expand his recently acquired realm. In 539 BCE, he turned his attention to the Neo-Babylonian Empire, defeating its armies and marching into Babylon. His Persian Empire now incorporated the territories controlled by Babylonia, including Mesopotamia, Syria, Phoenicia, and Judah, and had become the largest empire to have existed in the Near East to that point. Organizing and administering this massive domain required the use of governors, whom Cyrus generally selected from local areas, a prudent move in a world where rebellions were common.

Cyrus died in in battle in 530 BCE, leaving the throne and empire to his son Cambyses II. The first task for Cambyses was to continue preparing for the invasion of Egypt his father had planned. A large fleet was built in the Mediterranean and a massive land force assembled for crossing the Sinai. The invasion began in 525 BCE. The defending Egyptians were soon overwhelmed, and the pharaoh retreated up the Nile but was captured. Having now added Egypt to his already large empire, Cambyses took on the role of pharaoh, adopting the proper titles and caring for the Egyptian religious institutions. This practice of respecting local traditions was a common feature of Persian expansion and helped to win support in newly acquired areas.

Under Cambyses II, the Persian Empire stretched from the edges of India to the shores of the Aral Sea, the Aegean coast of Anatolia, and the Nile River and included everything in between. Then, just as Cambyses was reaching the height of his power, a Persian revolt broke out in 522 BCE in support of his brother Bardiya. On his way to put down the rebellion, Cambyses II died, leaving the future of the empire uncertain but allowing for the rise of possibly Persia’s most famous and powerful leader, Darius I.
