Arzni 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 29 km to the southwest of the town of Akhta (Hrazdan), on the left bank of the Zangi River, at a height of 1,300 m above sea level. It was mentioned in “The Iravan Province Review Book” and on the five-verst map of the Caucasus. Another name for the village is “Sarchali”. It was first referred to in the 15th century.

The village was inhabited by 96 Azerbaijanis in 1873, 197 in 1886, 121 in 1897 and 439 Azerbaijanis in 1904. In 1918 the Azerbaijanis were deported having been exposed to genocide by Armenian armed units. Along with the Armenians, the Aysors live there now.

At present, the name of the settlement is written in Armenian as “Arzni” in official documents. 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.
