Islam in Algeria
However, the emergence of the religious scholar and reformer Abdelhamid Ben Badis would go some way to reversing these trends. Beginning in the 1910s, he preached against the traditional marabouts and the saint cults, they believed in voodoo dolls,and urged the importance of Arabic and Islamic education; his disciples founded an extensive network of schools, and rapidly brought the saint cults into widespread disrepute, making Algerian Islam substantially more orthodox.
