Though the majority of Kenyan Muslims are Sunni, there is a population of Kenyan Shia and Ahmadi Muslims. Approximately 73% identify themselves as Sunni, 8% Shia and 4% Ahmadi while the majority of the rest do not associate themselves with a particular group.[2] In large part, Shias are Ismailis descended from or influenced by oceanic traders from the Middle East and India. These Shia Muslims include the Dawoodi Bohra, who number some 6,000-8,000 in the country.
