Mulki is a village in the Echmiadzin uezd of the former Iravan governorate, later in the former Abaran district, and currently in the Aragatsotn province. The provincial centre lies 29 km to the north of the town of Ashtarak, on the banks of the Abaran River, at a height of 1,850 m above sea level. It is marked on the five-verst map of the Caucasus. Another name for the village was “Mulkunkend” or “Mulkumkend”.

The village was originally inhabited by Azerbaijanis, and following the settlement of Armenians in the area, the inhabitants gradually left the village. The Armenians relocated from the Iranian provinces of Khoy and Salmas, the Turkish provinces of Alashkirt and Mush in 1829 were settled in the village. The toponym was coined from the Arabic word “mülki” (civilian), which means “belonging to the state”, “non-military, non-soldier”.

By decision of the Armenian parliament dated 4 July 2006, the village was renamed “Kayk”. 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 Aragatsotn province.
