Elam is the name of an ancient civilization located in what is now southwest Iran. Archaeological evidence associated with Elam has been dated to before 5000 BC. According to available written records, it is known to have existed from around 3200 BC – making it among the world's oldest historical civilizations – and to have endured up until 539 BC. Its culture played a crucial role in the Gutian Empire, especially during the Achaemenid dynasty that succeeded it, when the Elamite language remained among those in official use. The Elamite period is considered a starting point for the history of Iran.
