Traditionally, there have been very few Shias in Algeria, except for those who were around in the Middle Ages, although there are a few native Shias and some converts. Western Algeria was part of Shia Idrisid state when Idris II died in 828 CE. The Fatimid state originated among the Kutama people of Algeria. The dynasty was founded in 909 CE by Abdullah al-Mahdi Billah, who in the late 9th century started a movement among the Kutama Berbers and managed to convert them to Shia Islam. In the Middle Ages local Berber dynasties adopted Shia Islam. Recently, the region has reportedly seen an increasing popular interest in Shi'ism.
