Azerbaijan Religions
Azerbaijan is an overwhelmingly Muslim country. Estimates include 91.6% (CIA), 93.4% (Berkley Center, 2012), 99.2% (Pew Research Center, 2009) of the population identifying as Muslim. Most are adherents of Shia branch (approximately 85% Shi'a according to Berkley Center, 2012); with a minority (15%) being Sunni Muslim, differences traditionally have not been defined sharply. Most Shi'a are adherents of orthodox Ithna Ashari school of Shi'a Islam. Following many decades of Soviet atheist policy, religious affiliation is nominal in Azerbaijan and Muslim identity tends to be based more on culture and ethnicity than religion. Traditionally villages around Baku and Lenkoran region are considered stronghold of Shi'ism. In some northern regions, populated by Dagestani (Lezghian) people, Sunni Islam is dominant. Folk Islam is widely practiced but there is little evidence of an organized Sufi movement.
The rest of the population adheres to other faiths or are non-religious, although they are not officially represented. Other traditional religions or beliefs that are followed by many in the country are the Armenian Apostolic Church (in Nagorno-Karabakh), the Russian Orthodox Church, and various other Christian denominations.
Like all other post-Soviet states formerly ruled by the Soviet Union, Azerbaijan is a secular state; article 48 of its Constitution ensures the liberty of worship, to choose any faith, or to not practice any religion, and to express one's view on the religion. The law of the Republic of Azerbaijan (1992) "On freedom of faith" ensures the right of any human being to determine and express his view on religion and to execute this right. However, a 1996 law states that foreigners have freedom of conscience, but are denied the right to "carry out religious propaganda", i.e., to preach, under the threat of fines or deportation. According to paragraphs 1-3 of Article 18 of the Constitution the religion acts separately from the government, each religion is equal before the law and the propaganda of religions, abating human personality and contradicting to the principles of humanism is prohibited. At the same time the state system of education is also secular.
