Archaeological evidence[5] indicates that the Urartian military fortress of Erebuni was founded in 782 BC by the orders of King Argishti I on the Arin-Berd hill within modern-day Erebuni district, to serve as a fort and citadel guarding against attacks from the North Caucasus.

After the Sovietization of Armenia, the administrative area of Erivan (Yerevan) was gradually expanded to include the ancient territories of Erebuni, commonly known as Arin-Berd.

Mushavan and Verin Jrashen, originally villages at the eastern outskirts of Yerevan, were eventually absorbed by the city in 1965.

On 8 August 1991, based on a decision passed by the National Assembly of Armenia, the territory of the Lenin raion was renamed Erebuni.

However, the vast majority of the members of the Azeri community fled to Azerbaijan as a result of the population exchange during the First Nagorno-Karabakh War.
