Hajidur is a village in the Borchali uezd of the former Tiflis governorate, later in the former Allahverdi (Tumanyan) district, and currently in the Lori province. The provincial centre is located 60 km to the northeast of Boyuk Garakilsa (Vanadzor), at a height of 1500 m above sea level.

The village was initially inhabited by Azerbaijanis who gradually left it following the settlement of Armenians in the region.

The toponym was coined by combining the personal name “Haji” and the word “tur” meaning “a house, place of residence”. It is an anthropotoponym.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 3 January 1935, the village was renamed “Tsakhkashat”. 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 Lori province.
