Although Kurds are predominantly Sunnis, there is stormy hostility between the Sunni Kurds and the Shi'ite Kurds. These differences have class overtones, and the lower class minorities are associated with the more unorthodox sects of Islam. These have proven to be the most fervently rebellious parts of Kurdish society. Even among the Sunni Kurds, there are traces of an earlier pagan and violent type faith which sets them apart from other Muslims. In the rural areas, a few still believe in jinnis, demons, and elements of animal worship.
Religious fraternities operate throughout Kurdistan.
However, as time went by, their authority began to crumble. Today, their spiritual and economic power is being challenged. The Kurds have walked in the darkness of Islam for many years. Although the New Testament is now available in their language, there are only 551 known Northern Kurd believers. Physically, the Kurds live in very poor conditions.
