The remaining dioceses of the Church are in the areas of Buganda, of Northern Uganda, of Ankole and Kigezi, and of Rwenzori.
In 1954, four archdeaconries were created: West Nile; Lango and Acholi; Teso and Karamoja; and Mbale; there was an Archdeacon of Elgon until that point.
In preparation for the creation of the independent church province, the diocese was split in three parts in 1961: Teso and Karamoja became Soroti diocese; the Northern Province the Diocese of Northern Uganda; and Mbale, Bugisu and Bukedi remained and was renamed Mbale.
Erected from the Diocese of Namirembe in 1972, the mother church is Christ Cathedral, Bugembe (in Jinja District).
Founded in 2016 from the Busoga diocese; All Saints' Pro-Cathedral, Iganga.
