Masaka Diocese started as part of a huge Vicariate, then became a Pro – Vicariate, then Vicariate and finally a Diocese. The brief history below is meant to show the beginning, growth and development of this famous and historical Diocese that emerged as singular in its own right in African Church History of the second and third missionary movements. Singular because it was the only Diocese that emerged as such in the whole period from 1482 to 1939 when a Vicariate led by a black Bishop eventually became a Diocese under an indigenous Bishop on 25th March 1953.

On 16th March 2019 Bishop Serverus Jjumba was appointed Bishop of Masaka Diocese. He was ordained Bishop on 6th July, 2019 at Kitovu Sports Arena by Bishop John Baptist Kaggwa assisted by Bishop Joseph Antony Zziwa, Bishop of Kiyinda Mityana Diocese, Late Bishop Lambert Bainomugisha, Auxiliary Bishop of Mbarara Archdiocese, Archbishop Luigi Bianco, then Apostolic Nuncio to Uganda and Late Archbishop Cyprian Kizito Lwanga, Archbishop of Kampala Archdiocese.
