The Diocese of Amravati created by the Decree 'Cum Petierit' dated May 8, 1955 was formerly a part of the Archdiocese of Nagpur. It comprised four districts of Vidarbha viz. Amravati, Akola, Buldana and Yavatmal and the three districts of Marathwada, viz Aurangabad, Parbhani and Nanded.

By another decree 'Paescit Ubique' dated May 8, 1955, Pope Pius XII appointed Bp Joseph Albert Rosario, msfs, the First Bishop of Amravati.

Holy Father Pope Paul VI by the Decree 'Qui Arcano' of December 17, 1977 created the Diocese of Aurangabad for which the three civil districts, Aurangabad, Parbhani and Nanded of Marathwada region, got separated from the Diocese of Amravati.

Thus the present Diocese of Amravati consists of only four civil districts of Vidarbha region of Maharashtra state viz. Amravati, Akola, Buldana and Yavatmal.
