The former Italian Catholic Diocese of Sant'Angelo dei Lombardi-Bisaccia, in the Province of Avellino, Southern Italy, existed until 1921, when it was united into the Archdiocese of Conza-Campagna to form the Archdiocese of Conza-Sant'Angelo dei Lombardi-Bisaccia.
[1][2] The Diocese of Sant' Angelo de' Lombardi was created under Pope Gregory VII, but its first known bishop is Thomas, in 1179, when the see was a suffragan of the archdiocese of Conza.
In 1540 under the episcopate of Rinaldo de' Cancellieri, it was united to the Diocese of Bisaccia (the ancient Romulea); it appears first as a bishopric in 1179.
In 1818 it was incorporated with the See of Monteverde, the earliest known bishop of which is Mario (1049), and which in 1531 was united to the Archdiocese of Canne and Nazareth, from which it was later separated.
