Cyrus the Great, the founder of the first Persian Empire, conquered the millennia-old city of Babylon on October 12th, 539 BCE. Local inscriptions tell us it was without a fight, or even a siege. This was probably because local rulers recognized all was lost and decided to give in and hope for a good settlement.
But Greek historian Herodotus tells a more exciting version. According to him, the city’s walls crossed the river Euphrates. Unable to get past the walls, Cyrus had sappers drain the river upstream into a nearby lake, until the river’s level fell “about to the middle of a man’s thigh.” As the Babylonians celebrated a religious festival the Persians simply walked – dripping – into a dancing city.
Whether it was surrendered or it was captured, Babylon would belong to the Persian Empire and Cyrus’ descendants for the next 200 years.
