Datis

Datis or Datus (Greek: Δάτης, Old Iranian: *Dātiya-, Achaemenid Elamite: Da-ti-ya) was a Median noble and admiral who served the Persian Empire during the reign of Darius the Great (522–486 BC). He is known for his role in leading the Persian amphibious expedition against Greece in 490 BC during the Greco-Persian Wars. Along with Darius's nephew Artaphernes, he was tasked with subduing Eretria and Athens, succeeding the previously defeated Mardonius. While some later sources claim Datis died during the Battle of Marathon (490), this is not corroborated by other evidence. His later career is largely unknown except that his sons served as cavalry leaders under Xerxes I (486–465 BC). Datis was familiar with Greek affairs, maintained connections with Greek officials, respected Greek deities, and even attempted to speak Greek.
