The Achaemenid Empire was an ancient Persian empire that existed from the 6th century BCE to 330 BCE. Founded by Cyrus II, later known as Cyrus the Great, it became the largest empire of the ancient world and was conquered by Alexander the Great.

Origins

The Achaemenid Empire emerged in Persia under Cyrus II, who overthrew the Median Empire in 550 BCE and unified much of Iran under his rule. The dynasty took its name from Achaemenes, a traditional ancestor of the royal house.

Expansion and administration

Under Cyrus, Cambyses II, and Darius I, the empire expanded rapidly and developed a sophisticated system of imperial rule. Sources describe a network of provinces, tribute collection, roads, and royal administration that helped govern a vast territory.

Peak and territorial reach

At its height, the empire controlled lands from Anatolia and Egypt through Mesopotamia, the Levant, Iran, and Central Asia to the Indus Valley. It was widely regarded in antiquity as a major superpower, stretching across parts of Europe, Asia, and Africa.

Fall

Alexander the Great invaded the empire in the late 4th century BCE and defeated the last Achaemenid rulers. By 330 BCE, Persian imperial independence had ended.
