Islam is the predominant religion in Algeria, with the vast majority of adherents being
Sunni Muslims. The dominant
madhhab is
Maliki, there are a few followers of the
Hanafi rite among people of Turkish descent. According to the 2021
CIA World Factbook, Muslims make up approximately 99% of the population, while Pew Research estimated this figure at 97.9% in 2020. Additionally, there are around 290,000
Ibadis, primarily residing in the
M'zab Valley in the
Ghardaia region. Islam was introduced to Algeria by the
Umayyad dynasty during the Arab expansion, beginning with the invasion led by Uqba ibn Nafi.
Christianity was introduced to North Africa during the Roman era. Its influence waned during the Vandal invasions but was later reinforced under Byzantine rule. However, indigenous Christianity in North Africa persisted beyond the Muslim conquest until the early 15th century. Before Algeria’s independence, the country was home to more than 1.3 million Christians, most of whom were of
European descent, along with a small number of Algerians who had converted to Christianity. Following independence, the majority of these settlers emigrated to France. Since the 1960s, an increasing number of Algerians have converted to Christianity. The number of Algerian converts to Christianity, most of whom practice in secret, is estimated to range between 50,000 and 200,000. Today, most Christian Algerian citizens belong to
Protestant denominations, which have faced growing governmental pressure in recent years, including numerous forced church closures.
Algeria’s Jewish community, with roots dating back to antiquity, was largely composed of descendants of Spanish refugees. Before independence in 1962, about 140,000 Jews lived in Algeria, but most emigrated to France due to their French citizenship. By the 1990s, only around 1,000 remained, with the last synagogue in Algiers vandalized in 1977. == References ==
