Teispes
Teispes was a king of Anshan in ancient Persis during the mid-7th century BCE, recognized in Achaemenid royal inscriptions as the son of Achaemenes and the father of Cyrus I, thereby serving as the great-grandfather of Cyrus the Great and the progenitor of a collateral line leading to Darius I.[1].pdf) His rule over Anshan, an erstwhile Elamite center in southwestern Iran, marked an early phase of Persian consolidation in the region prior to the empire's expansion under his descendants.[1] The primary evidence for Teispes derives from later propagandistic texts such as the Cyrus Cylinder and Darius I's Behistun inscription, which trace divergent royal genealogies back to him to legitimize their rule, though no contemporary records of his reign survive.[1].pdf) These sources portray him as a "great king," but details of his achievements or the extent of his domain remain obscure, reflecting the limited archaeological and textual attestation for pre-imperial Persian rulers.[2]
