Elamite language
Around 1500 BCE, the Middle Elamite period began with the rise of the Anshanite dynasties. Their rule was characterized by an "Elamisation" of Susa, and the kings took the title "king of Anshan and Susa". While, previously, the Akkadian language was frequently used in inscriptions, the succeeding kings, such as the Igihalkid dynasty of c. 1400 BCE, tried to use Elamite. Thus, Elamite language and culture grew in importance in Susiana.
