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.
Medieval Muslim Algeria
Medieval Muslim Algeria was a period of Muslim dominance in Algeria during the Middle Ages, roughly spanning the millennium from the 7th century to the 17th century. Unlike the invasions of previous religions and cultures, the coming of Islam, which was spread by Arabs, was to have pervasive and long-lasting effects on North Africa. The new faith, in its various forms, would penetrate nearly all segments of society, bringing with it armies, learned men, and fervent mystics; in large part, it would replace tribal practices and loyalties with new social norms and political idioms.
