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.
Algeria
Berber and Modern Standard Arabic are the official languages. Algerian Arabic (Darja) is the language used by the majority of the population. Colloquial Algerian Arabic is heavily infused with borrowings from French and Berber.
