Polad Ayrum is a village in the Gazakh uezd of the Yelizavetpol governorate, later in the former Karvansara (Ijevan) district, and currently in the Tavush province. The provincial centre lies 30 km to the south-west of the town of Karvansara, at a height of 1,050 m above sea level. Until the end of 1930, it had been within the former Dilijan district.

The village was solely inhabited by Azerbaijanis: 290 in 1873, 390 in 1886, 220 in 1897, 263 in 1904, 347 in 1914, and 685 Azerbaijanis in 1916. In March 1919 the Azerbijani population of the village was exposed to the aggression of Armenian armed groups and deported or massacred. After the establishment of Soviet power in present-day Armenian territory, the surviving villagers were able to return to their homes. The village was inhabited by 302 Azerbaijanis in 1922, 319 in 1926, 452 in 1931, 565 in 1939, 543 in 1959, 755 in 1970 and 750 Azerbaijanis in 1979. In late November 1988 the Azerbaijanis were deported by the state of Armenia. At present, Armenians live there.

The toponym was coined on the basis of the word “polad” and the name of the Ayrum Turkic tribe. Later, the name of the village was abbreviated, the second component of the oeconym, the Turkic ethnonym “Ayrim” was dropped and it was formalised as “Polad”.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 3 April 1991, the village was renamed Khachardzap. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was included in the administrative territory of the Tavush province.
