Tomyris also called Thomyris, Tomris, Tomiride, or Queen Tomiri, reigned over the Massagetae, an Iranian people from Scythian pastoral-nomadic confederation of Central Asia east of the Caspian Sea, in parts of modern-day Turkmenistan, Afghanistan, western Uzbekistan, and southern Kazakhstan. Tomyris led her armies to defend against an attack by Cyrus the Great of the Achaemenid Empire, and, according to Herodotus, defeated and killed him in 530 BC.
