0Deioces or Dia—oku  was the founder and the first شاه as well as priest of the ماد ایمپراتورلوغو government. His name has been mentioned in different forms in various sources; including Herodotus, who has written his name as Dēiokēs. Deioces' name is derived from the Iranian word Dahyu-ka-, meaning "the lands" (above, on and beneath the earth).0|}}
