Church of Caucasian Albania

The Church of Albania or the Albanian Apostolic Church was an ancient, briefly autocephalous church established in the 5th century. In 705, It fell under the religious jurisdiction of the Armenian Apostolic Church as the Catholicosate of Aghvank centered in Caucasian Albania, a region spanning present-day northern Azerbaijan and southern Dagestan.

In medieval times, the Gandzasar monastery served as the See of the Catholicosate of Aghvank of the Armenian Apostolic Church, which continued to exist until 1828 (or 1836) when it was formally abolished by the Russian authorities, following the forced cession of the last territories in the Caucasus maintained under Iranian Qajar rule per the Treaty of Turkmenchay and the Russo-Persian War (1826–1828).
