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.
Algerian nationalism
A new generation of Muslim leadership emerged in Algeria at the time of World War I and grew to maturity during the 1920s and 1930s. It consisted of a small but influential class of "évolués", other Algerians whose perception of themselves and their country had been shaped by wartime experiences, and a body of religious reformers and teachers. Some of these people were members of the few wealthy Muslim families that had managed to insinuate themselves into the colonial system in the 1890s and had with difficulty succeeded in obtaining for their sons the French education coveted by progressive Algerians. Others were among the about 173,000 Algerians who had served in the French army during World War I or the several hundred thousand more who had assisted the French war effort by working in factories. Many Algerians stayed on in France after 1918, and sent the money they earned there to their relatives in Algeria. In France they became aware of a standard of living higher than any they had known at home and of democratic political concepts, taken for granted by Frenchmen in France, which "colons", soldiers, and bureaucrats had refused to apply to the Muslim majority in Algeria. Some Algerians also became acquainted with the pan-Arab nationalism growing in the Middle East.
