Iran History before Islam: According to documents, from the ancient times, Iran Flat has been residential. As the obtained works show, Iran tribes have lived along the rivers, springs, & also Zagros Mountain, as well as Kashan hill of Siyalk & hill of Hesar.
Current documents show that around 12000 years ago, i.e. the era of New Stone without Clay, the historical hill of Choqa Golan near Mehran town, Elam province, has been one of the first agricultural origins. It seems that favorable climate & abundant of products, have resulted in reviving the innovation feeling & modernistic enthusiasm of that era people.
The effects obtained from the Archeological sites of Damqan, Tarang Tappe of Gorgan, Haft Cheshme/ Seven Springs of Gorgan, Hasanlu Hill, Marlik Hill of Roodbar & Shush, show the Antiquity of the fifth millennium BC.
Elamite: On the 3rd millennium BC, in huge parts of Zagros (West) including Lorestan, Pish Kouh, Posht Kouh, & some South parts of Khuzestan till Kerman, the civilization of Elamite was born; which lasted till 1st millennium AD. The capital of them was Shoush; afterwards of which became the winter capital of Achaemenid.
Elamite, had commercial relationship with Town governments of Mesopotamia and Mohenjo-daro, alongside of Send River.
From remained works of Elamite, some works of Khuzestan, Ziggurat of Choqazanbil in Shush, plus the Stone carves of Ize can be named. Elamites performed the customs of Nowruz. Coinciding with Elamites kings in Khuzestan, Lulu’iha, Gutiha, & Kasiha on the region of Zagros Mounts, & on South East of Uremia Lake were stationed; from this same era, migration of Aryans were started.
Aryans: Aryans were the tribes of Mad, Part, & Pars. Mad Tribe on the valleys & flats of Zagros region (present Hamedan), Pars Tribe on Zagros South Flats(present Fars), & Part Tribe on the flats of Gorgan & Khorasan were settled. About 250 BC, Part Tribe from Khorasan went ahead towards West & South West of Iran & their Empire, was founded on Tisfun; the life of which lasted till 224 AC.
From unity of Aryan Tribes to the dominance of Arabs over Iran, 4 important tribes of Mad, Achaemenid, Ashkanian, & Sassanid, ruled over Aryan land.
Defeating the Mad Tribes & dominating over their capital, Achaemenid were the founders of Iran first Empire; i.e. 522- 485 BC or 550 BC.
After the extinction of Achaemenid kingdom, soluki System for a while dominated over Iran; the result of which was the integration of Iran & Helenistic cultures. During the peak power of Systems of Achaemenid, Ashkani, & Sasanid, the commercial relationships were also promoted; as going through South & Mesopotamia to India, they brought Indian Spice to Eastern & Western Lands.
Silk Road, with 8000km length, continuing from China to Istanbul alongside the coastlines of Mediterranean see & passing through Iran, resulted in trade boom.
From Achaemenid era, the traces of once green & Waterful Takht-e Jamshid & Pasargadae Town on the Morqab Plain of Fars Province, have remained.
Constructing of Takht-e Jamshid, with an order from First Darius Hakhamaneshi was started; which continued till the era of Ardeshir-e Hakhamaneshi. Ordered by Cyrus, Pasargadae Town/Parse as the place of palace on the north of Takht-e Jamshid, on 5 zones & in the area of 6 km2 has been built. Pasargadae, bearing his tribe name, was Cyrus’ Capital; the building of which was constructed by Greek architects. That’s why in it, the Greek architectural style is quite evident. The Tomb of Cyrus is also situated in Pasargadae.

At the very mouth of this cave, the statue of Shapur, 7 m height, is seen,
(dating back to 1700 years ago), formed by carving over inner stone column of cave. This statue is yet standing, with only its hands broken.
Anahita Temple, Kazerun, inspired by Achamenid architecture, is roof-less. It is interesting that, the temple is placed at the depth of 6 m from the earth; to which the water of Shapur River can be steepened. In fact, Bishapur Temple, is a Water Temple(one of the 4 elements attributed to the Venus goddess). From the other works of Sassanid, Falak-ol Aflak Citadle of Lorestan, can be named, which during Sassanid era has been utilized as a state military citadel.
Throughout this era, there have been so many erosion wars between the local rulers; thanks to which, the ground for domination of some tribes like Saljugi Turks, Mongols, & Teymurian, invaded from Cntral Asia to Iran, was provided. In the 1st century, with the collapse of the Sassanid Empire, Iranian accepted the Islam Religion.
