Ancient Jewish History: The Medes
The kingdom of Media was located in the region between the southwest Caspian sea and the Persian Gulf. Biblical sources, as well as Greek historians, often confused the Median kingdom with the nearby Persians. The Median tribe cooperated with the Babylonians but, in the 6th century BCE, were defeated by Cyrus of Persia.
