Our story of the amazingly swift rise of the Persian empire doesn't begin until around 550 BC. But long, long before that, civilisations and cultures had risen and fallen in the territory of the modern nation of Iran. The oldest culture we know of in Iran - the Elamites - flourished from around 8000 years ago; as old as the world's oldest civilisation (in nearby Sumer - southern Iraq today). Their main centres were Anshan in the southwest Zagros mountains, and Susa (Shush) on the plain in what's now known as Khuzistan (Khuzestan), Susiana or Ilam.

The Elamites were not Iranians, nor were they Semitic. They spoke a language of their own, completely unrelated to the later languages of the Iranian peoples, or indeed to any other known language ("as distant from Akkadian as Chinese is from English"). Their racial connections cannot be known for sure - but they were not related to the Medes, Persians and other Iranian peoples who started to arrive on the Iranian plateau later, from about 1000 BC. They did, though, occupy much of the territory where Iranians later came to dominate, and their culture and art had an influence on later developments in the Persian empire.

Proto-Elamite period c 4000 - c 2700 BC
A very ancient city-based civilisation had existed in what is now south-west Iran since at least 4000 BC, centred around Susa on the plain, and Anshan in the Zagros mountains to the east. Susa's earliest remains date to around 4200 BC. Influence from Sumerian culture, exemplified by pottery finds dates from around 3200 BC. Bronze working was already happening in Luristan. By 3000 BC, the Elamite language was being written down in cuneiform script.).

Competition with Sumer grew- with each dominating the other for some periods. Expansion beyond the original heartlands was usually short-lived. There's evidence of trade with the Indus Valley civilisation in NW India.
Middle Period c1500 - 1100 BC
The Elamite empire was at its most powerful under the Shutrukid dynasty, but despite some successes agains the Babylonians and Assyrians it power began to decline - and it dissappears from the records for several centuries.
. Between 1300 and 1200 BC, they were building ziggurats like Choga Zanbil, and controlling an extensive trading network reaching far to the east.

Click here for more pictures of Chogha ZanbilChogha Zanbil (Dur Untash) was built when the Elamite empire was at its most powerful under king Untash Naparisha. The city had three sets of walls encircling a huge five-storeyed temple (a ziggurat) at the centre. The ground plan of the ziggurat is a square, with each side measuring 105m. The red bricks look new. The temple was built to honour Inshushinak, the chief god of the Elamites. The remains of palaces and some other temples have been found between the outer and middle walls, but the area between the inner and middle walls was packed with temples to other Elamite deities. Over 5000 inscriptions have been found on the bricks used to build the complex - one row in every ten was inscribed. One reads:
I, Untash Naparisha, have built a temple of golden-coloured brick, silver-coloured brick, stone of ..., black opal stone and white stone of the area and have dedicated this holy area to the gods Inshushinak and Naparisha. May the curse of Inshushinak, Naparisha and Kiririsha fall on the person who destroys, harms or moves its ... stones or bricks and may his descendants be removed from underneath the sun.
Neo-Elamite period c 1100 - 540 BC
The Elamites had always had to compete with the Assyrians or Babylonians for control of Mesopotamia. Eventually they were completely crushed by the Assyrian Ashurbanipal in 640 BC. He boasts:
In a month I levelled the whole of Elam. I deprived its fields of the sound of human voices, the tread of cattle and sheep, the refrain of joyous animals.

The Assyrians destroying Susa (646 BC)
Elam never really recovered and had been conquered again by the Medes when they crushed the Assyrians (around 605 BC). In the southeastern part of Elam in the Zagros mountains, a small kingdom had developed under the rule of the "Persian" Teispes around 650 BC (as recorded on the Cyrus cylinder). In the Babylonian texts it is called Anshan. When the Medes were conquered by Cyrus in 540 BC, the ancient Elamite capital at Susa also became Persian.
Most of our knowledge of the ancient Elamites comes from their capital at Susa and nearby sites in Khuzistan. But several sites east of the Zagros mountains may also have Elamite connections. Two of the most interesting are:
Tepe Sialk- a mysterious mound near Kashan, where human remains from 3,500 BC have been discovered. It may have been the site of a ziggurat.
Jiroft- a wealthy trading centre on the route to the east.
Anshan
The Iranians who had been infiltrating the Anshan region since the end of the 2nd millennium had by this time (7th century BC) assimilated with the Elamites and established an identity as Persians - Teispes and his successors were Persian kings of Anshan, part of the land of Elam. So inter-connected were the two peoples by now, that it's rather pointless trying to separate them. The Elamite culture persisted, and the language continued to be written and used for administration throughout the Persian empire. The oldest text on the Bisitun inscription of Darius is in Elamite. Cyrus' own name is Elamite - and it's been suggested that the Persian empire should properly be called the Elamite empire!
