The Achaemenid Empire (Old Persian: Hakhāmanishiya) was a dynasty in the ancient Persian Empire with high cultural and economical achievements during its highest power. At the height of their power, around 500 BC, the Achaemenid rulers of Persia ruled over territories roughly encompassing today's Iran, Iraq, Armenia, Afghanistan, Turkey, Bulgaria, eastern parts of Greece, Egypt, Syria, much of what is now Pakistan, Jordan, Israel, Palestine, Lebanon, Caucasia, Central Asia, Libya, and northern parts of Arabia. The empire ruled by Persia eventually became the largest empire of the ancient world.
