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 the Jews in Algeria
After Houari Boumediene came to power in 1965, Jews were persecuted in Algeria, facing social and political discrimination and heavy taxes. In 1967-68 the government seized all but one of the country's synagogues and converted them to mosques. By 1969, fewer than 1,000 Jews were still living in Algeria.
