Bozyokhush is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Gizil Goch (Gukasyan) district, and currently in the Shirak province. The provincial centre lies 32 km to the east of the town of Gumru, and at a height of 2,045 m above sea level. It was marked on the five-verst map of the Caucasus.

The village was initially inhabited by Azerbaijanis who gradually left it after Armenians had been removed from Türkiye and settled in the territory of the Iravan Khanate in accordance with the Treaty of Adrianople (1829).

The toponym was formed by combining the word “boz” used in Azerbaijani in the meaning of “grassless, bare, woodless” and the word “yokhush” meaning “an uphill, upward slope”.

The village was renamed “Musaelyan” by the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 12 November 1946. 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 Shirak province.
