Islam in Azerbaijan

Islam is the majority religion in Azerbaijan, but the country is considered to be the most secular in the Muslim world. Various reports have estimated 97.3% (CIA, 2020) or 99.2% (Pew Research Center, 2006) of the population identifying as Muslim; with the majority being adherents of the Shia branch (55-85%), while a significant minority (15-45%) are Sunnis. Traditionally, the differences between these two branches of Islam have not been sharply defined in Azerbaijan.

Most Shia Muslims in the country follow the Ja'fari school of Shia Islam, while Sunni Muslims typically adhere to either the Hanafi or Shafi'i school. Due to many decades of Soviet atheist policy, religious affiliation in Azerbaijan is often nominal and Muslim identity tends to be based more on culture and ethnicity than on religion. Shia Islam is prevalent in the western, central, and southern regions of the country. Traditionally, villages around Baku and the Lankaran region are considered Shia strongholds. In contrast, Sunni Islam is dominant in the northern regions.
