Susuz is a village in the Echmiadzin uezd of the former Iravan governorate, later in the former Talin district, and currently in the Aragatsotn province. The provincial centre lies 63 km to the northwest of the town of Ashtarak, at a height of 1,610 m above sea level. The village was originally inhabited by Azerbaijanis, but following the settlement of Armenians there, its population gradually left the village. Armenians were moved from the Turkish provinces of Mush and Malazgirt in 1828–1830 and settled there.

The village was inhabited by 90 Azerbaijanis in early 1918. In February-March 1918 the Azerbaijani inhabitants were deported from the village having been exposed to Armenian aggression.

The toponym was coined by adding the suffix “-suz” to the word “su” used in the sense of “a river, small river, pond” in Turkic.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 12 November 1946, it was renamed “Tsamakasar”. 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 Aragatsotn province.
