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.
Apostasy in Islam
Freedom of religion in Algeria is regulated by the Algerian Constitution, which declares Sunni Islam to be the state religion (Article 2) but also declares that "freedom of creed and opinion is inviolable" (Article 36); it prohibits discrimination, Article 29 states "All citizens are equal before the law. No discrimination shall prevail because of birth, race, sex, opinion or any other personal or social condition or circumstance".
