The Achaemenid Empire (c. 550–330 BCE), sometimes known as First Persian Empire, was an empire in Southwest Asia, founded in the 6th century BCE by Cyrus the Great. It expanded to eventually rule over significant portions of the ancient world which at around 500 BCE stretched from the Indus Valley in the east, to Thrace and Macedon on the northeastern border of Greece.
