Elam was part of the early cities of the Ancient Near East during the Chalcolithic (Copper Age). The emergence of written records from around 3000 BC also parallels Mesopotamian history where writing was used slightly earlier. Elamite strength was based on an ability to hold various areas together under a coordinated government that permitted the maximum interchange of the natural resources unique to each region. Traditionally, this was done through a federated governmental structure.
