Christianity in Algeria
Currently, North Africa is primarily Muslim: Islam is the state religion of Algeria, Libya, Morocco and Tunisia. While the practice and expression of other faiths is guaranteed by law, the same legal framework tends to restrict minority religions from actively seeking conversion to their religion, or even building or repairing churches. Converts to Christianity may be investigated and searched by the authorities as well as punished. There is some evidence that there has been an increase in conversions to Christianity among North African Muslims in recent years, even though in many cases the government will not change the religion from Islam on any citizens' identity cards. Despite this, the total number of Christians remains very low relative to the populations of these countries. In 2009, the percentage of Christians in Algeria was less than 2%. In this same survey, the UNO counted 100,000 Roman Catholics and 45,000 Protestants in the country. Although Christians are a religious minority in Algeria, churches built during French rule can still be found.
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.
