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.
Muslim Brotherhood
The Muslim Brotherhood reached Algeria during the later years of the French colonial presence in the country (1830–1962). Sheikh Ahmad Sahnoun led the organization in Algeria between 1953 and 1954 during the French colonialism. Brotherhood members and sympathizers took part in the uprising against France in 1954–1962, but the movement was marginalized during the largely secular FLN one-party rule which was installed at independence in 1962. It remained unofficially active, sometimes protesting the government and calling for increased Islamization and Arabization of the country's politics.
