The Achaemenid Empire was an ancient Iranian empire that ruled over much of Southwest Asia, Central Asia, and parts of Eastern Europe and North Africa from the 6th century BC to the 4th century BC. The empire was founded by Cyrus the Great, who conquered the Medes in 550 BC and then went on to conquer Lydia, Babylonia, Assyria, Egypt, and many other lands. The Achaemenid Empire was the largest empire in the world at the time, and it was also one of the most tolerant and cosmopolitan empires in history.
