Life In Iran

• Pre-Islamic statehood (625 BC – 651 AD)
The Medes are credited with the unification of Iran as a nation and empire (625–559 BC), the largest of its day, until Cyrus the Great established a unified empire of the Medes and Persians leading to the Achaemenid Empire (559–330 BC), and further unification between peoples and cultures. After Cyrus' death, his son Cambyses II continued his father's work of conquest, making significant gains in Egypt.
Following a power struggle after Cambyses' death, Darius the Great was declared king (ruled 522–486 BC). Under Cyrus and Darius, the Persian Empire eventually became the largest and most powerful empire in human history up until that point. The borders of the Persian empire stretched from the Indus and Oxus Rivers in the east to the Mediterranean Sea in the west, extending through Anatolia (modern day Turkey) and Egypt.
In 499 BC, Athens lent support to a revolt in Miletus which resulted in the sacking of Sardis. This led to an Achaemenid campaign against Greece known as the Greco-Persian Wars which continued through the first half of the 5th century BC. During the Greco-Persian Wars Persia made some major advances and razed Athens in 480 BC, but after a string of Greek victories the Persians were forced to withdraw. Fighting ended with the peace of Callias in 449 BC.
