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.
History of Algeria
A new generation of Islamic leadership emerged in Algeria at the time of World War I and grew to maturity during the 1920s and 1930s. Various groups were formed in opposition to French rule, most notable the National Liberation Front (FLN) and the National Algerian Movement.
