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.

This action, however, did not meet with the approval of Marshal MacMahon, governor-general of Algeria, who feared that the maghrebian would resent it as an infraction of the religious peace, and thought that the Muslim faith, being a state institution in Algeria, ought to be protected from proselytism; so it was intimated to the prelate that his sole duty was to minister to the colonists. Lavigerie made it clear that he had come to serve the whole population of Algeria.
