The word Urartu and all other words, names connected with the history of Urartian kingdom were decripted by one single scientist. His name is Piotrovski. He was an arceologist , and had great interest in Urartian history. But his research of the Urartian inscriptions in Erebuny, Rusakhinili and other Urartian sites was concluded under the control of Communist Party Central Committee of Moscow(Armenia was Armenian SSR at that time). During his research he factually decripted only the consonants of Urartian language. So the word “urartu” was initially decripted as “r-r-t”, the word “erebuny” as “r-b-n” and so on. If we put the right sonants (in opinion of many present day Armenian scientists) we’ll have “a-r-a-r-a-t” instead of “r-r-t” and “e-r-e-b-a-n” instead of “r-b-n”. This system applies to a big number of Urartian words decripted by Piotrovski. And there was a reason to wrongly decript those words. Because in case he had done it in the right way, one tiny part of the USSR would become some 600-700 years older and the single successor of a rich culture. The result was that in the section of Urartu in the “History of the USSR” textbook ended with this phrase-”The Georgian, Azerbajani and Armenian fraternal peoples descended from Urartians”. Georgian language belongs to the Caucasian family and has some relation to Svanetian, Lezgin languages but no relation to Armenian. Azeri or actually karakoyunlu existence happened to the region only in 13-th century in as a result of migration. The fall of Urartian kingdom dates 590 BC. The “Anabasis” of Ksenophon (Greek historian) gives a detailed describtion of the Yervandouny Armenian kingdom in 401 BC. And the most important, he writes that the people of that kingdom were speaking one language and had the same traditions of agriculture, music etc. If Urartians and Armenians were not the very same people, Yervandouny(Ortonid) kingdom could not develop to an integrated state like that.
“Yet the Hurrians did not disappear from history. Away to the North in their Armenian homeland, they entrenched themselves and build up the kingdom of Urartu.”

The kingdom’s native name was Biainili, also spelt Biaineli, (from which is derived the Armenian toponym Վան “Van”) I. M. Diakonoff, “Hurro-Urartian Borrowings in Old Armenian.” Journal of the American Oriental Society, Vol. 105, No. 4 (Oct. – Dec., 1985), pp. 597–603
but prior to the 8th century BC, they also called their now united kingdom “Nairi” Chahin, Mack The Kingdom of Armenia. London: RoutledgeCurzon, 2001, pp. 71ff. ISBN 0-7007-1452-9.

“by the order of Darius the Great of Persia, the country referred to as Urartu in Assyrian is called Arminiya in Old Persian and Harminuia in Elamite.” Skjaervo, Prods Oktor, “An Introduction to Old Persian”, Harvard 2002
“Urartu maintained its independence and power, going through a mere dynastic change, as a local Armenian dynasty (later to be called the Orontids) overthrew the ruling family with the help of the Median army. Ancient sources support the latter version: Xenophon, for example, states that Armenia, ruled by an Orontid king, was not conquered until the reign of Median king Astyages (585– 550 BC) – long after Median invasion of the late 7th century BC.” Xenophon.Cyropedia. 3.7.

“Igor Diakonoff accepts a Hurro-Urartian etymology as plausible for thirteen lexemes in Old Armenian” John A. C. Greppin; I. M.

And the most important part, there was never proven that there was some Prygo-Armenian migration from Balkans, and especially a conquest. Behistunian Inscription says very clearly RRT(Ur-ar-tu) in Assyrian is Arminiya in old Persian.
