Elamite
Elamite refers to the language and the people of ancient Elam, a region in southwestern Iran along the Susiana Plain. The Elamite state and civilization emerged in the third millennium BCE, with major urban centers at Susa, Anshan, and later Chogha Zanbil. Elamite political power persisted in various forms into the early first millennium BCE, and the Neo-Elamite period ended after the rise of the Achaemenid Persians in the late 6th century BCE. The Elamites maintained extensive contact with Mesopotamia through trade, diplomacy, and conflict.
Language and writing: Elamite is generally treated as a language isolate, not demonstrably related to Semitic
Legacy: The Elamite language and literature contributed to the understanding of early Iranian history and Near
