Algeria–Holy See relations
Although Islam is the state religion of Algeria, the Holy See has maintained a comparatively good relationship with the Algerian authorities, with Léon-Étienne Duval being famously recognized as the "bishop of Muslims" after the departure of French colonists.
Ahmadiyya in Algeria
In 2013, the Algerian Ministry of Religious Affairs expressed concern over the rise of a number of radical religious movements, including Ahmadism which according to them "is becoming as deeply entrenched in North Africa as takfiri Salafism and Wahhabism", and decided to take action by strengthening the monitoring and control of the places targeted by the radical Islamists for recruits. In 2016, Ahmadi sect members had been detained and accused of various offences with detentions occurring in Larbaâ, Algiers, Skikda, Sidi Ameur, M'Sila. and Beni Saf.
