Garabulag is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Aghin (Ani) district, and currently in the Shirak province. The provincial centre lies 25 km to the southwest of the town of Gumru, adjacent to the Arpachay, at a height of 1470 m above sea level. It was marked in “The Iravan Province Review Book” and on the five-verst map of the Caucasus.

 According to the Treaty of Adrianople (1829), following the settlement of Armenians in the territory of the Iravan Khanate, the Azerbaijanis living in the village moved to Türkiye.

The name of the village was coined from the name of a spring in the village. It was coined from the words “gara” (black) and “bulag” (a spring), meaning “poor quality, non-drinkable”. It is a hydrotoponym.

By decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 30 June 1945, the village was renamed “Isahakyan” (the surname of the Armenian writer Avetik Isahakyan). According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative territory of the Shirak province.
