I believe the Elamite Empire must be added to the list of sections in the box of "History of Iran and Persia" at the top of the page.
It is now becoming increasingly clear that Iran had vast civilizations and centers of population long before the arrival of the Aryans and the establishment of the Achaemenid empire. (e.g. Jiroft civ. and Elamites)
This is not a minor issue. These civilizations were independent of those of Mesopotamia and deserve greater attention.
Seized and burned by Alexander the Great's conquering army, shaken by uncounted earthquakes, eroded by 25 centuries of rain, fluctuating temperatures and scouring winds, Persepolis-the greatest of the royal residences of ancient Persia-is a definitive ancient ruin.
Yet, the place remains an awesomely impressive sight 2,500 years after it was built. Even today, those who step up to its gigantic terrace of 125,000 square meters and see its majestic columns are filled with a sense of awe drifting into a dream-like trance.
A dream in which one tries to visualize the beauty and dazzling splendor of Persepolitan palaces before their sad destruction.
