The Diocese of Arsharunik is one of the oldest dioceses in Armenia, formed by St. Gregory the Illuminator in the second diocesan department. In the middle of the 4th century, during the reign of Catholicos St. Nerses the Great, it was annexed to the bishopric of Bagrevand. It became the main episcopate of the country when Catholicos St. Sahak Partev returning from Persia in 432 AD, settled in the province of Bagrevand. The famous bishops of Bagrevand during this period were the 5th century philosopher Yeznik Koghbatsi and the patriarch of the Armenian historiography Movses Khorenatsi.
