Several bronze-era states flourished in the area of Greater Armenia, including the Hittite Empire (at the height of its power), Mitanni (South-Western historical Armenia), and Hayasa-Azzi (15001200 BC). The Nairi people (12th to 9th centuries BC) and the Kingdom of Urartu (1000600 BC) successively established their sovereignty over the Armenian Highland. Each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. A large cuneiform lapidary inscription found in Yerevan established that the modern capital of Armenia was founded in the summer of 782 BC by King Argishti I. Yerevan is the world's oldest city to have documented the exact date of its foundation.
