Islam in Zanzibar

Islam is the most prominent religion on the semi-autonomous Zanzibar archipelago and could be considered the Islamic center in the United Republic of Tanzania. Around 99% of the population in the islands are Muslim, with two-thirds being Sunni Muslim and a minority Ibadi, Ismaili and Twelver Shia. Islam has a long presence on the islands, with archeological findings dating back to the 10th century, and has been an intrinsic part in shaping mercantile and maritime Swahili culture in Zanzibar as well as along the East African coast.
