Unlocking the past (2nd edition) by Lost Worlds investigates the very latest archaeological finds at Persepolis.
Under the leadership of Cyrus the Great, Persia ruled the world's first true empire, centered in Iran and stretching from Europe to Egypt to India.
The heart of ancient Persia is in what is now southwest Iran, in the region called the Fars. In the second half of the 6th century B.C.E., the Persians (also called the Achaemenids) created an enormous empire reaching from the Indus Valley to Northern Greece and from Central Asia to Egypt.
