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.
Protestant Church of Algeria
Protestantism has been present in Algeria since the early days of French rule in Algeria. The first synod of the Reformed churches was held in 1843 and the French Methodists began mission work in Béjaïa around 1883. By 1914, American Methodist missionaries were also well established in Algeria. After the traumatic independence of Algeria, many local Christians fled the country and by 1970, mission run schools and properties have been nationalised.
