Kasaman is a village in the Novo-Bayazid uezd of the former Iravan governorate, later in the former Basarkechar (Vardenis) district, and currently in the Gegharkunik province. The provincial centre lies 95 km to the southeast of the town of Kavar (Gavar), at the foot of the mountain, at a height of 2060 m above sea level. It was marked on the five-verst map of the Caucasus.

 The village was inhabited by Azerbaijanis: 166 in 1831, 379 in 1873, 492 in 1886, 671 in 1897, 713 in 1908, 966 in 1914 and 894 Azerbaijanis in 1916. On 13-20 February 1919 the Azerbaijanis were expelled from the village by Armenian armed forces. Following the establishment of Soviet power in the territory of the present-day Armenia, the surviving Azerbaijanis managed to return to the village. The village was inhabited by 249 Azerbaijanis in 1922, 414 in 1926, 569 in 1931 and 1,200 Azerbaijanis in 1987. In 1988 the Azerbaijanis were expelled from their historical and ethnic lands by the Armenian government. At present, the village is inhabited by Armenians.

The toponym was coined from the ethnonym “Kasaman”, one of the Kazakh Turkic tribes.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 27 January 1978, the village was renamed “Bahar”, and by decision of 3 April 1991, it was renamed “Arpunk”. 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 Gegharkunik province.
