- HISTORICAL NOTE:
On March 25th. 1937 one of the new Prefectures erected in Ethiopia was the Prefecture of Neghelli Borana, in the Province of Sidama, entrusted to the Pontifical Institute for Foreign Missions (P.I.M.E). With this new Prefecture, the Sidama Province became a missionary jurisdiction of its own. Following the expulsion of the P.I.M.E. Missionaries in 1941, the Prefecture of Neghelli was administered by the Apostolic Vicariate of Harar up to 1972, but already since December 1964 the Comboni Missionaries had accepted the Holy See invitation to work in the then Sidama Province. Fr. E. Ceccarini, Mccj, was the head of the Mission and was later appointed Vicar Delegate of the same. In 1972 the Prefecture was re-instated as an independent ecclesiastical Jurisdiction named Apostolic Prefecture of Hawassa; in 1973 Msgr. Armido Gasparini, Mccj, was appointed Apostolic Administrator of the same. The Prefecture was erected as an Apostolic Vicariate in 1979, with the consecration of its first Bishop, Msgr. A. Gasparini, Mccj, succeeded in 1994 by Msgr. Lorenzo Ceresoli, Mccj. On March 21, 2009, H.E. Msgr. Giovanni Migliorati, Mccj, became the third Vicar Apostolic of Hawassa.
The Vicariate of Hawassa comprises Sidama and Gedeo Zones; Amaaro and Burji special Weredas of Southern Nations and Nationalities Peoples Representatives State (SNNPRSRS); Guji and Borana Zones of Oromiya Region and Liben Zone of Somali Region.
