19th century.
Islam had arrived in Uganda from the north and through inland networks of the East African coastal trade by the mid-nineteenth century. Some Baganda Muslims trace their family's conversion to the period in which Kabaka Mutesa I converted to Islam in the nineteenth century. Islam entered Uganda through the Buganda route in the 1840s and the northern Uganda route through the Turko- Egyptian influences. Kasozi, (1986: 23) gives 1844 as the year when the first Muslim Arab trader; Ahmed bin Ibrahim reached the King's court in Buganda.
