Armenians call themselves "" (, pronounced plural: հայեր, [haˈjɛɾ). The name has traditionally been derived from "Hayk" (), the legendary patriarch of the Armenians and a great-great-grandson of Noah, who, according to Movses Khorenatsi (Moses of Khorene), defeated the Babylonian king Bel in 2492 BC and established his nation in the Ararat region. It is also further postulated that the name "Hay" comes from, or is related to, one of the two confederated, Hittite vassal states—Hayasa-Azzi (1600–1200 BC). Ultimately, "Hay" may derive from the Proto Indo-European words "póti" (meaning "lord" or "master") or "*h₂éyos"/"*áyos" (meaning "metal").
