Evidence: They defeated the Oirads and returned with plundered goods. Oirats (Mongolian: Ойрад, Oirad, Mongolian pronunciation: [ɔiˈrɑt or Ойрд, Oird; Kalmyk: Өөрд; in the past, also Eleuths) are the westernmost group of the Mongols whose ancestral home is in the Altai region of Siberia, Xinjiang and Western Mongolia.
