New World Encyclopedia writes about the fall of Akkadian Empire

“Naram-Sin recorded the Akkadian’s wars against the Armani or Armeni people in Ararat. The Armeni is a reference to Armen who was the ruler of the Armenian tribe (Armen’s followers, the Armenians, were refered to as Armeni or Armens at the time).

It is not known if Sargon, grandfather of Naram-Sin, and Manishtushu, father of Naram-Sin, also fought against the Armeni people of Ararat during their rule of the Akkadian Empire. It is highly probable however considering that Naram-Sin recorded multiple wars with the Armeni people of Ararat.

It is not known at this time if war with the Armeni people of Ararat contributed to the collapse of the Akkadian kingdom.

However, the Akkadian Empire was already starting to crumble during the reign of Shar-kali-sharri, the son of Naram-Sin, and by the end of his reign the empire collapsed outright from the invasion of barbarians of the Zagros Mountains known as “Gutians.” Some speculate that a bad harvest, climactic change or even a giant meteor contributed to the decline.”
