Cyrus the Great built, in a single lifetime, the largest empire the world had yet seen2. Rising from a minor kingdom, he overthrew the Medes, the fabulously rich Lydians and mighty Babylon, and forged the Achaemenid Persian Empire3. He was remembered not only for his conquests but, unusually, for the tolerance he showed the peoples he ruled.
The rise of Persia
Cyrus began as king of a small Persian realm under the overlordship of the Medes. Around 550 BC he overthrew his Median overlord2 and united the two peoples under his own rule, the first step in a breathtaking expansion that would carry Persian power from the Aegean to Central Asia.

Lydia and Babylon
He turned west against Lydia and its proverbially rich king Croesus, taking his capital Sardis around 546 BC, then east and south until, in 539 BC, he entered Babylon, the greatest city of the age, with little resistance1. In a single generation the small kingdom of Persia had become a world empire.

The tolerant conqueror
What set Cyrus apart in ancient memory was how he ruled. Rather than crushing conquered peoples, he generally respected their customs, religions and local rulers1. The famous Cyrus Cylinder records his settlement of Babylon in this spirit4, in the language of a royal proclamation of its time, and the Hebrew Bible remembers him for allowing the exiled Jews to return home and rebuild their temple5, a reputation for clemency rare among conquerors.

Death in the east
Cyrus died around 530 BC campaigning on his empire's eastern frontier; Greek tradition tells of his fall against the Massagetae and their queen Tomyris6, though the details are uncertain. He was laid to rest in a simple tomb at Pasargadae that still stands1.
