Arab and Safavid rule
Islam arrived in Nagorno-Karabakh with Arabs in the seventh century, gradually increasing as Islamic nations ruled the region.
In the sixteenth century, the first shah of the Safavid dynasty, Ismail I (r. 1486–1524) established Shia Islam as the state religion.[2] The Safavid dynasty would have a strict policy of enforcing Shia Islam, which would bring political conflict with the Sunnis of the neighbouring Ottoman Empire.[2]
Russian & Soviet rule
In 1806, Nagorno-Karabakh was annexed by the Russian Empire from the Persian Qajar dynasty, and Emperor Paul I of Russia issued a charter titled "About their admission to Russian suzerainty, land allocation, rights and privileges", it was noted that the Christian heritage of the Karabakh region and all their people were admitted to the Russian suzerainty.[3]
There are hundreds of churches scattered throughout Artsakh, because the vast majority of the population belongs to the Armenian Apostolic Church. Some notable ones include:
