Greek historians wrote of the wars between the Saka and the Medes, as well as their wars against Cyrus the Great of the Persian Achaemenid Empire where Saka women were said to fight alongside their men. According to Herodotus, Cyrus the Great confronted the Massagetae, a people related to the Saka, while campaigning to the east of the Caspian Sea and was killed in the battle in 530 BC. Darius I also waged wars against the eastern Sakas, who fought him with three armies led by three kings according to Polyaenus. In 520–519 BC, Darius I defeated the "Sakā tigraxaudā" tribe and captured their king Skunkha (depicted as wearing a pointed hat in Behistun). The territories of Saka were absorbed into the Achaemenid Empire as part of Chorasmia that included much of the Amu Darya (Oxus) and the Syr Darya (Jaxartes), and the Saka then supplied the Achaemenid army with large number of mounted bowmen. They were also mentioned as among those who resisted Alexander the Great's incursions into Central Asia.
