550–330 BC
The Median Empire was the first empire on the territory of Persia. By the 6th century BC, after having together with the Babylonians defeated the Neo-Assyrian Empire. In Greek references to "Median" people there is no clear distinction between the "Persians" and the "Medians"; in fact for a Greek to become "too closely associated with Iranian culture" was "to become medianized, not persianized". The Medes were able to establish their own empire, the largest of its day, lasting for about sixty years, from the sack of Nineveh in 612 BC until 549 BC when Cyrus the Great established the Achaemenid Empire by defeating his overlord and grandfather, Astyages, king of Media.
The Achaemenid Empire was the first of the Persian Empires to become a world empire. At the height of its power, the Empire spanned over three continents, namely Europe, Asia, and Africa, and was the most powerful empire of its time. It also eventually incorporated the following territories: in the north and west all of Asia Minor (modern Turkey), parts of the Balkan peninsula - Thrace, Macedon and Paeonia, and most of the Black Sea coastal regions or present day southern and eastern Bulgaria, northern Greece, and Macedonia; in the west and southwest the territories of modern Iraq, northern Saudi Arabia, Jordan, Israel, Lebanon, Syria, all significant population centers of ancient Egypt and as far west as portions of Libya; in the east modern Afghanistan and beyond into central Asia, and parts of Pakistan.
Encompassing approximately 5.5 million square kilometers at its height in 500 BC,[23][24] the Achaemenid Empire was territorially the largest empire of antiquity.
