Christianity came to North Africa in the Roman era. Its influence declined during the chaotic period of the Vandal invasions but was strengthened in the succeeding Byzantine period, only to disappear gradually after the Arab invasions of the seventh century.

The Roman Catholic Church was reintroduced after the French conquest, when the diocese of Algiers was established in 1838. Proselytization of the Muslim population was at first strictly prohibited; later the prohibition was less vigorously enforced, but few conversions took place. The several Roman Catholic missions established in Algeria were concerned with charitable and relief work; the establishment of schools, workshops, and infirmaries; and the training of staff for the new establishments. Some of the missionaries of these organizations remained in the country after independence, working among the poorer segments of the population. In the early 1980s, the Roman Catholic population numbered about 45,000, most of whom were foreigners or Algerians who had married French or Italians. In addition, there was a small Protestant community. Because the government adopted a policy of not inquiring about religious affiliation in censuses or surveys to avoid provoking religious tensions, the number of Christians in the early 1990s was not known.

The Jewish community is of considerable antiquity, some members claiming descent from immigrants from Palestine at the time of the Romans. The majority are descendants of refugees from Spanish persecution early in the fifteenth century. They numbered about 140,000 before the Algerian revolutionary period, but at independence in 1962 nearly all of them left the country. Because the 1870 Crémieux Decrees, which aimed at assimilating the colons of Algeria to France, gave Jews full citizenship, most member of the Jewish community emigrated to France.

The government of independent Algeria discouraged antiSemitism , and the small remaining Jewish population appeared to have stabilized at roughly 1,000. It was thought to be close to this number in the early 1990s. Although no untoward incidents occurred during the Arab-Israeli wars of 1967 and 1973, a group of youths sacked the only remaining synagogue in Algiers in early 1977.
