Tajirabag is a village in the Iravan uezd of the former Iravan governorate, later in the former Ellar (Kotayk, Abovyan) district, and currently in the Kotayk province. The provincial centre lies 46 km to the southwest of the town of Akhta (Hrazdan), at a height of 1,550 m above sea level. It was noted as the village of “Tejirdink”, the timar of Haji Hussein with a revenue in the amount of 4500 akchas in “The Iravan Province Review Book” and was marked as “Tajirabag” on the five-verst map of the Caucasus. Other names for the village were “Tajirabad”, “Tajarabag”.

Following the settlement of Armenians there, the Azerbaijani population of the village gradually left the village.

The toponym was coined on the basis of the ethnonym “Tajirli” which belongs to the Dulgadirli tribe of the Oghuz.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 4 April 1946, it was renamed “Dzoraghbyur”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Kotayk province.
