Teïspes (from Greek Τεΐσπης; in Old Persian: 𐎨𐎡𐏁𐎱𐎡𐏁[2] Cišpiš; Akkadian: 𒅆𒅖𒉿𒅖 Šîšpîš,[3] Elamite: Zi-iš-pi-iš)[4] ruled Anshan in 675–640 BC. He was the son of Achaemenes of Persis and an ancestor of Cyrus the Great.[4] There is evidence that Cyrus I and Ariaramnes were both his sons.[4] Cyrus I is the grandfather of Cyrus the Great, whereas Ariaramnes is the great-grandfather of Darius the Great.
According to 7th-century BC documents, Teispes captured the Elamite city of Anshan, speculated to have occurred after the Persians were freed from Median supremacy, and expanded his small kingdom. His kingdom was, however, a vassal state of the Neo-Assyrian Empire (911–605 BC). He was succeeded by his second son, Cyrus I.[4]
