Algeria
Islam is the predominant religion in Algeria, with its adherents, mostly Sunnis, accounting for 99% of the population according to a 2012 CIA World Factbook estimate, and 97.9% according to Pew Research in 2010. There are about 150,000 Ibadis in the M'zab Valley in the region of Ghardaia.
Religion in Algeria
After independence, the Algerian government asserted state control over religious activities for purposes of national consolidation and political control. Islam became the state religion in the new constitution and the religion of its leaders. No laws could be enacted that would be contrary to Islamic tenets or that would in any way undermine Islamic beliefs and principles. The state monopolized the building of mosques, and the Ministry of Religious Affairs controlled an estimated 5,000 public mosques by the mid-1980s. Imams were trained, appointed, and paid by the state, and the Friday khutba, or sermon, was issued to them by the Ministry of Religious Affairs. That ministry also administered religious property, the habus, provided for religious education and training in schools, and created special institutes for Islamic learning.
