2,500 years ago Persia was a great empire; regarded as the forerunner of the Roman Empire. However in spite of its size and strength it had an adversary that would seal its doom. Persia’s nemesis was a smaller empire - Macedonia; ruled by Alexander The Great.
This documentary shows how the failure of one king can lead to the downfall of a whole empire and how Alexander could manage to win against his superior enemy - The Persians.
The Persian Empire was formed under Cyrus the Great, who took over the empire of the Medes, and conquered much of the Middle East, including the territories of the Babylonians, Assyrians, the Phoenicians, and the Lydians.
Cambyses, Son of Cyrus the Great, continued his conquests by conquering Egypt. The Achaemenid Persian Empire was ended during the Wars of Alexander the Great, but Persian Empire arose again under the Parthian and Sassanid Empires of Iran, followed by Iranian post-Islamic Empires like Safavids, up to the modern day Iran.
