Yukhari Aylanli is a village in the Echmiadzin uezd of the former Iravan governorate, later in the former Uchkilsa (Echmiadzin, Vagharshapat) district, and currently in the Armavir province. The provincial centre is located 21 km to the northeast of the town of Serdarabad (Armavir), to the southwest of Alagoz mountain and at a height of 875 m above sea level. Another name for the village was “Aylanli- Abdulrahman”. It was marked on the five-verst map of the Caucasus. Until 1828 the village had been solely inhabited by Azerbaijanis.

According to the Treaties of Turkmenchay (1828) and Adrianople (1829), the Armenians who removed from Iran and Türkiye were settled in the village. The village was inhabited by 50 Azerbaijanis along with the Armenians in 1831. They were ousted from the village by Armenians in the 1840s. At present, the village is inhabited only by Armenians.

The toponym was coined by combining the word “yukhari” denoting a distinctive feature and the Turkic tribal name “Aylanli”.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 4 April 1946, the village was renamed “Tsakhkunk”. 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 Armavir province.
