Chatmadagh was a village in the territory of the Iravan uezd of the former Iravan governorate, in the former Gamarli (Artashat) disrtict, and currently in the Ararat province. Another name for the village was Chatmadash. The name of the village was marked as “Chatma” on the five-verst map of the Caucasus. The second component of the name of the village “dagh/dash” was omitted and officially documented as Chatma.

The village was solely inhabited by Azerbaijanis: 41 in 1873, 57 in 1886, 162 in 1897, 51 in 1904, 178 in 1914 and 190 Azerbaijanis in 1916. The Azerbaijanis were attacked, massacred or expelled from the village by Armenian armed units in 1918. After the establishment of Soviet power in present-day Armenia, the Azerbaijanis who survived could return to their lands. The village was inhabited by 29 Azerbaijanis in 1922, 18 in 1926 and 37 Azerbaijanis in 1931. In accordance with the decision of the USSR Council of Ministers “On the resettlement of collective farmers and other Azerbaijani population from the Armenian SSR to the Kur-Araz lowland of the Azerbaijan SSR” dated 23 December 1947, the Azerbaijanis were forcibly deported to Azerbaijan. Later,, the village was abolished. At present, it is ruined.

The toponym was coined by combining the word “chatma” meaning “side by side in one direction” and the word “dagh”. The toponym means “a village built in one direction at twin mountains.”
