The vast majority of Muslims in Sudan adhere to Sunni Islam of Maliki school of jurisprudence, deeply influenced with Sufism.[2] There are also some Shia communities in Khartoum, the capital.[3] The most significant divisions occur along the lines of the Sufi brotherhoods. Two popular brotherhoods, the Ansar and the Khatmia, are associated with the opposition Umma and Democratic Unionist Parties respectively. Only the Darfur region is traditionally lacking the presence of Sufi brotherhoods found in the rest of the country.[4]
