Who founded the Achaemenid Persian Empire in the sixth century BCE?

Cyrus the Great founded the Achaemenid Persian Empire in the sixth century BCE.

Cyrus II ruled Anshan before defeating his grandfather Astyages, king of Media, in 550 BCE. This victory joined Persian and Median power and created the foundation of the Achaemenid Empire. Cyrus then conquered Lydia and Babylon, making Persia the dominant imperial power in the ancient Near East.

He is remembered not only for conquest but also for pragmatic imperial rule. Babylonian records describe his entry into Babylon in 539 BCE, while the Cyrus Cylinder presents him as a restorer of temples and local traditions. Modern claims that the cylinder was the first human-rights charter go beyond what the ancient text actually says.

Cyrus died campaigning in Central Asia around 530 BCE. His son Cambyses II succeeded him, but Cyrus’s imperial framework endured for more than two centuries.
